As a China manufacturer, Dongfa Intelligent provides the Molded Case Circuit Breaker with Residual Current Protection for low-voltage distribution systems, including main incoming circuits and high-capacity branch circuits. The GNM1L Series is available in 125A, 250A, 400A, 600A, and 800A frame sizes, with AC400V rated operating voltage, residual operating current settings from 30mA to 1000mA, and time-delay or non-delay protection. With an Icu of up to 65kA at 400V, the series offers configurations for different rated current, leakage current, short-circuit current, and protection coordination requirements.

Dongfa Intelligent COAFLE-32 Residual Current Operated Circuit Breaker is designed for low-voltage terminal distribution systems requiring integrated residual current, overload, and short-circuit protection. The series covers rated currents from 6A to 63A, with 30mA/50mA residual operating current, 4500A/6000A rated short-circuit capacity, and 1P+N, 2P, 3P, 3P+N, and 4P configurations for different single-phase and three-phase distribution systems.

Dongfa Intelligent supplies DZ47LE Series Residual Current Protection RCBO for terminal distribution systems requiring combined circuit protection. The series covers 6A–63A rated current and supports multiple pole configurations, 30mA/50mA residual operating current, and C/D trip characteristics. It is suitable for lighting, socket circuits, commercial distribution, industrial control cabinets, and other terminal circuits requiring residual current, overload, and short-circuit protection.

The Electronic Molded Case Circuit Breaker MCCB from Dongfa Intelligent is designed for low-voltage distribution and motor protection applications. The GNM1E series covers frame currents from 125A to 800A and uses an electronic trip unit with an adjustable setting current range of 0.4–1.0In. Available in 3- or 4-pole configurations and L/M/H breaking capacity levels, the circuit breaker provides configurable long-time, short-time, and instantaneous overcurrent protection according to the selected application and technical requirements.

The Molded Case Circuit Breaker MCCB from Zhejiang Dongfa Intelligent Electric Technology Co., Ltd. is a low-voltage circuit protection device for power distribution, equipment, and motor circuits. It covers rated currents from 16A to 1250A, with 400V breaking capacities from 25kA to 100kA and 3P/4P configurations. The thermal-magnetic trip unit provides overload and short-circuit protection, while different frame sizes and breaking capacity levels allow selection according to load current and fault level. Standard orders can be supplied with a lead time of 7–15 working days, with custom configurations available upon request.

Dongfa Intelligent supplies the Universal Intelligent Air Circuit Breaker ACB with a 1600A frame rating for low-voltage distribution projects requiring configurable protection and operating functions. Its control system can be matched with different auxiliary power supplies, while the undervoltage release provides selectable delay settings of 1s, 3s, 5s, or instantaneous operation. Motor and manual operating options are also available for different installation and control requirements.
