Core Advantages

AC/DC Universal 110V

The AC/DC 110V Latching Solenoid for Switchgear operates on both AC110V and DC110V control power. This AC/DC universal configuration allows the same voltage specification to be used for applicable AC and DC control circuit configurations.

PCB Terminal Board for Organized Wiring

The product is equipped with a PCB terminal board and 4-position green terminal block. The terminal structure provides an organized connection point for control wiring and facilitates installation, inspection, and replacement.

Spring Self-Reset Structure

A built-in reset spring returns the push rod to its initial position after the coil is de-energized. This spring self-reset structure supports automatic return of the interlocking mechanism without manual reset.

Hard Magnetic Coil and Chrome-Plated Push Rod

The hard magnetic coil provides the magnetic force required for solenoid action. The chrome-plated carbon steel push rod provides a durable contact surface for repeated mechanical movement, while the galvanized housing protects the internal components.

L-Shaped Mounting Bracket

The L-shaped metal mounting bracket has two long oval mounting holes. The adjustable hole structure allows the installation position to be fine-tuned according to the available mounting space and mechanical alignment.

Application and Interlocking Function

PT Handcart Interlocking

The AC/DC 110V Latching Solenoid for Switchgear can be installed in PT handcart interlocking mechanisms to control the locking and release action according to the applicable switchgear operating conditions.

Circuit Breaker Cabinet Anti-Misoperation Interlocking

In circuit breaker cabinets, the solenoid works with the control circuit and mechanical mechanism to support interlocking and help restrict operation when the required conditions are not satisfied.

Five-Prevention Interlocking Systems

The product can be integrated into five-prevention interlocking systems as an electrically controlled locking component. Its push rod provides the mechanical movement required by the applicable interlocking arrangement.

Power Distribution and Substation Switchgear

The solenoid is suitable for high voltage switchgear used in power distribution systems, substations, and related electrical installations.

Structure and Installation

PCB Terminal Board and Terminal Block

The AC/DC 110V Latching Solenoid for Switchgear uses a PCB terminal board with a 4-position green terminal block for control wire connection. The flame-retardant terminal structure provides an organized wiring point within the switchgear.

L-Shaped Metal Mounting Bracket

The solenoid is supplied with an L-shaped metal mounting bracket for fixed bolt mounting. Two long oval mounting holes allow position adjustment during installation.

Lead Wires and Insulating Terminals

Two blue multi-strand copper lead wires with red insulating terminals are included as part of the standard solenoid assembly.

Materials and Process

The product uses a hard magnetic coil, galvanized metal housing, chrome-plated carbon steel push rod, flame-retardant PCB, and flame-retardant plastic terminal block. The material configuration supports the electrical connection, mechanical movement, and mounting structure required for switchgear interlocking applications.

Technical Specifications

Replacement Compatibility

For replacement projects involving the AC/DC 110V Latching Solenoid for Switchgear, please provide the original solenoid model, operating voltage, mounting dimensions, push rod stroke, installation space, application, and required quantity. Product drawings or installation dimensions can also be provided for matching confirmation.

Product Use Guide

1. Install the solenoid in the designated switchgear interlocking position and align the push rod with the operating mechanism.
2. Connect the control wiring according to the terminal markings and apply the specified control power.
3. Check the locking action and confirm that the push rod returns automatically after the control power is removed.
4. Verify that the complete interlocking mechanism operates correctly before putting the switchgear into service.

FAQ

Q1: What does AC/DC universal 110V mean?

AC/DC universal 110V means the solenoid can operate on both AC110V and DC110V control power. It is not a 220V specification.

Q2: How is the PCB terminal board wired?

The AC/DC 110V Latching Solenoid for Switchgear uses a 4-position green terminal block. Control wires should be connected according to the applicable terminal markings and wiring requirements.

Q3: What is the difference between a latching solenoid and a closing or opening coil?

Closing and opening coils drive circuit breaker closing or opening operations, while a latching solenoid is used for interlocking and locking functions through its push rod.

Q4: How does the spring self-reset structure work?

The built-in spring returns the push rod to its initial position after the coil is de-energized, allowing automatic mechanical return.

Q5: What are the long oval mounting holes used for?

The long oval holes allow the mounting position to be adjusted within the available range, helping align the solenoid with the switchgear mechanism.

Q6: What information is needed for replacement matching?

Please provide the original model, operating voltage, mounting dimensions, push rod stroke, installation space, application, and quantity for compatibility confirmation.

Q7: What is the MOQ and lead time?

Standard products support an MOQ of 1 unit. The standard lead time is 7-15 working days, while customized products generally require 15-30 working days.
