MT-M1 3/4P AC Molded Case Circuit Breaker, 63A–1600A, Reliable Electrical Protection

Description:

The MT-M1 series molded case circuit breaker (MCCB) is engineered to deliver reliable protection and control in AC 50Hz power distribution systems, with rated operational voltages up to 400V and currents ranging from 63A to 1600A. Designed to safeguard circuits and connected equipment, the MT-M1 efficiently interrupts overloads, short circuits, and undervoltage conditions, while also managing occasional motor starting without compromising system integrity.

Compact yet robust, this MCCB features a superior breaking capacity and minimal arcing, ensuring long-term operational reliability. Its modular design allows both vertical and horizontal mounting, providing flexible installation in tight electrical panels or motor control centers. Fully certified to IEC 60947-2 and GB14048.2, the MT-M1 meets international quality and safety standards.

Applications:

The MT-M1 MCCB provides dependable protection in diverse electrical systems, including:

Main and secondary power distribution panels

Motor control centers and starter panels

Generator protection circuits

Industrial and manufacturing machinery

Commercial and residential electrical installations

Solar and wind energy integration systems

Description

Working Principle:The working principle of the MT-M1 series MCCB is to monitor circuit current and, in the event of overload, short circuit, or ground fault, automatically determine and trigger the mechanism to quickly interrupt the circuit. It also safely extinguishes the arc through an arc-extinguishing system, thereby reliably cutting off the fault and protecting the circuit and equipment.

MCCB

To ensure transportation safety, our electrical products are exported in reinforced wooden crates. The crates undergo heat treatment and bear the ISPM-15 mark, enabling swift customs clearance. The raised base design facilitates forklift operation, while internal shock-absorbing fastening ensures the products arrive intact. All exterior crates are clearly labeled and comply with international logistics standards.
