Introducción:
- The molded case circuit breakers manufactured by CNTN Eléctrico have a rated insulation voltage of 800V and are suitable for AC 50Hz circuits with a rated operating voltage of 690V and below (400V for the ZMM1-63 model) and a rated operating current from 63A to 800A. They are used for infrequent switching and starting of electric motors.
- Our MCCB 100A 4-pole circuit breaker features overload, short circuit, and undervoltage protection functions, capable of protecting circuits and power equipment from damage.
- Our circuit breaker features high short-circuit breaking capacity and short arc extinguishing time, making it an ideal choice for users.
- The CNTN electric MCCB 100A 4-pole circuit breaker uses a highly flame-retardant material, effectively isolating electrical arcs, and providing protection against dust, moisture, and electric shock. It can be directly installed in distribution cabinets or outdoor distribution boxes, preventing accidental contact with live parts.
- This MCCB offer flexible and versatile installation options, supporting fixed, plug-in, and withdraw-able mounting, and can be installed vertically or horizontally.
- CNTN Electric can not only produce MCCB 100A 4-pole circuit breakers but also 100A 2-pole and 100A 3-pole versions according to customer requirements.
- Our MCCB is suitable for three-phase four-wire circuits, and can also be used for three-phase three-wire and three-phase two-wire circuits.
- CNTN Electric not only manufactures MCCB 100A 4-pole circuit breakers in AC types, but also produces DC molded case circuit breakers.
- CNTN Electric not only produces MCCBs with white covers made of bakelite, but also produces MCCBs with gray and black covers made of plastic.
