Dongfa Intelligent supplies the AC/DC 110V Position Latching Solenoid for Switchgear for position-based interlocking in high voltage switchgear. The unit is designed to work with PT handcart position detection and circuit breaker cabinet interlocking circuits, using a hard magnetic coil to drive the chrome-plated push rod according to the configured control logic. Its PCB terminal board includes an arc suppression element, while the built-in spring provides automatic push rod reset after the applicable control action.
The AC/DC 110V Position Latching Solenoid for Switchgear is designed for PT handcart position interlocking and circuit breaker cabinet anti-misoperation interlocking. It works with the switchgear position detection circuit and operating mechanism according to the configured control logic.
An arc suppression element is installed on the PCB terminal board across the coil circuit. When the coil is switched off, the element helps suppress the voltage spike generated by the coil and reduce electrical interference on connected control components.
The solenoid supports both AC110V and DC110V control power. This AC/DC universal configuration allows the same voltage specification to be used with either AC or DC 110V control circuits. It is not suitable for 220V control power unless a corresponding 220V specification is selected.
A built-in spring provides automatic push rod return after the applicable control action is completed. The self-reset structure eliminates the need for manual reset and supports repeated interlocking operations in switchgear mechanisms.
The L-shaped metal mounting bracket uses long oval mounting holes, allowing the installation position to be adjusted within the available mounting range. This design helps match the solenoid with existing switchgear cabinet structures.
During PT handcart operation, the AC/DC 110V Position Latching Solenoid for Switchgear works with the position detection circuit to control the operating mechanism according to the detected handcart position.
When the handcart has not reached the specified position, the interlocking mechanism can keep the operating mechanism restricted. After the position signal meets the control requirements, the solenoid releases or locks according to the actual circuit design, allowing the next operating step to proceed.
The specific control arrangement can be configured as energize-to-lock or de-energize-to-lock depending on the switchgear circuit. The required logic should therefore be confirmed before replacement or new installation.
The product is supplied with a PCB terminal board and 4-position green terminal block. The integrated arc suppression element is installed on the PCB and works with the coil circuit to reduce voltage spikes generated during coil switching.
This configuration incorporates the suppression component into the solenoid assembly rather than requiring a separate external component, provided that the integrated circuit is compatible with the control system.

The main configuration of the AC/DC 110V Position Latching Solenoid for Switchgear includes the solenoid body, PCB terminal board with arc suppression element, 4-position green terminal block, L-shaped metal mounting bracket, blue lead wires, and chrome-plated metal push rod. The hard magnetic coil provides the electromagnetic action, while the push rod performs the mechanical interlocking action. The built-in spring provides automatic return after the applicable control action, and the PCB-mounted suppression element helps reduce voltage spikes during coil switching.
For replacement projects, please provide the original solenoid model, operating voltage, mounting dimensions, push rod stroke, position detection logic, and required quantity. Photos, drawings, or installation details can also be provided to help check mechanical and electrical compatibility before production.
The AC/DC 110V Position Latching Solenoid for Switchgear is installed in high-voltage switchgear PT handcart mechanisms for position-related interlocking and locking functions.
The solenoid can be installed inside circuit breaker cabinets where position interlocking is required to restrict or release the operating mechanism according to the cabinet control circuit.
This solenoid is suitable for switchgear used in substations and power distribution systems, particularly where PT handcart position detection and electrical interlocking are part of the equipment configuration.
The product can be used in high-voltage switchgear installed in power plant electrical systems for position-related interlocking applications.
The factory assembles switchgear accessory products on dedicated production lines. Position latching solenoids undergo action characteristic testing and dielectric withstand testing before shipment. Key operating characteristics, including push rod action and reset behavior, are checked according to applicable production and inspection requirements.
Dongfa Intelligent supplies high-voltage electrical equipment and related low-voltage electrical components, allowing switchgear builders to coordinate multiple product categories through one manufacturing supplier. Its product range covers high-voltage switchgear components as well as low-voltage protection and control products.
The company holds ISO 9001, ISO 14001, and ISO 45001 management system certifications and supports factory audits according to customer requirements.
Standard products typically have a lead time of 7-15 working days, while customized products generally require 15-30 working days. Standard products support trial orders from 1 unit. OEM/ODM requirements can be reviewed according to the required electrical configuration, mounting structure, and control application.
Yes, the AC/DC 110V Position Latching Solenoid for Switchgear can be considered for replacement projects when the electrical and mechanical requirements match. Please provide the original solenoid model, control voltage, mounting dimensions, push rod stroke, control logic, and quantity for compatibility checking.
Yes. The specified version is designed for both AC110V and DC110V control power. If the switchgear uses 220V control power, a corresponding 220V solenoid specification should be selected instead.
The connection depends on the switchgear's interlocking design. The solenoid can be coordinated with the PT handcart position detection circuit and operating mechanism, while the actual wiring and energizing sequence should follow the control circuit design.
The applicable control logic depends on the switchgear design. Energize-to-lock and de-energize-to-lock arrangements may be used. The required logic should be confirmed before production to ensure that the solenoid action matches the existing interlocking circuit.
Yes. The supplied configuration includes a PCB terminal board with an integrated arc suppression element and a 4-position green terminal block. This allows the suppression component to be incorporated into the solenoid assembly rather than added separately during installation.
Please provide the existing solenoid's mounting-hole spacing, available installation space, push rod stroke, push rod position, and overall mounting arrangement. Photos, drawings, or the original solenoid model can also be provided to help confirm mechanical compatibility.
Yes. Standard products support a trial order from 1 unit. This can be used to verify mechanical fit, electrical operation, and compatibility with the switchgear control circuit before a larger production order.
Standard products generally require 7-15 working days. Customized configurations generally require 15-30 working days. The final schedule depends on the required configuration and order quantity.
