The undervoltage release is an optional electromagnetic release accessory that comes standard with MCCBs. Its core function is to monitor the supply voltage, and when the voltage drops, disappears, or recovers abnormally, it triggers the circuit breaker to open, protecting the circuit and electrical equipment.

The electric operating mechanism is an actuator that replaces manual operation by being driven by a motor. Its core is to convert electrical energy into mechanical action to achieve automated control of circuit breaker opening, closing, and re-closing. Combined with the secondary circuit, protection system, and monitoring system of the distribution cabinet, it can complete remote, automatic, and intelligent power distribution management and control.

The auxiliary contact is the core built-in accessory of MCCB, which is divided into two categories: auxiliary contact (AX) and alarm contact (AL). It does not participate in the high-power on-off of the main circuit, but only serves as a low-voltage signal switch for signal feedback, status monitoring, and linkage control. It is a key accessory for MCCB to upgrade from a "simple protective device" to a "smart distribution component that can be monitored and linked"

The manual operating mechanism is the core accessory of the molded case circuit breaker (MCCB), whose primary function is to achieve safe on-off switching, status visualization, and anti-misconnection interlocking outside the cabinet. Its advantages lie in safe isolation, convenient operation, controllable cost, and strong adaptability, making it particularly suitable for distribution cabinets/drawer cabinets.

ARM5HU series MCCB is our latest high-voltage, high-performance thermomagnetic product. The product is suitable for AC 50/ 60Hz, with a rated working voltage of 1140V. It is infrequently used in circuits with a rated operating current of 630A. The circuit breaker has overload, short circuit, and undervoltage protection, which can protect the line and power equipment from damage. Products are mainly used in new energy. power systems, factories, and other occasions.
