TXM1 molded case circuit breaker (CM1)

1、 The TXM1 series plastic shell circuit breaker (CM1 plastic shell circuit breaker) is a new type of circuit breaker developed and researched using international advanced design and manufacturing technology. Its rated insulation voltage is 690V, suitable for circuits with AC 50Hz, rated working voltage of 400V and below, and rated working current of 800A and below for infrequent switching and motor starting. The circuit breaker has overload, short circuit, and undervoltage protection devices to protect the circuit and power equipment from damage. CM1 molded case circuit breakers are classified into four types based on their rated ultimate short-circuit breaking capacity (LCU): C-type (economy type), L-type (standard type), M-type (higher breaking type), and H-type (high breaking type). CM1 molded case circuit breaker has the characteristics of small size, high breaking height, short flying fox, and anti vibration, making it an ideal product for land and ship use. This molded case circuit breaker can be installed vertically (i.e. vertically) or horizontally (i.e. horizontally). This product complies with the requirements of IEC60947-2 and GB14048.2 standards. 2、 Model and specifications
