SJKM1L-400/4300 plastic shell circuit breaker with residual current protection

Scope of application
SJKM1LE plastic shell circuit breaker with residual current protection (hereinafter referred to as the circuit breaker) is one of the new circuit breakers developed and researched by our company using advanced design software and manufacturing technology. Its rated insulation voltage is 800V, suitable for infrequent switching and motor starting in circuits with AC 50Hz, rated working voltage of 400V, and rated working current value of 800A. Circuit breakers have
The overload, short circuit, and undervoltage protection functions can protect the circuit and power equipment from damage, and also provide protection against potential fire hazards caused by long-term grounding faults that can be detected by the overcurrent protection unit
Circuit breakers are classified into two types based on their rated short-circuit breaking capacity (LCU): M-type (higher breaking type) and H-type (high breaking type). This circuit breaker has the characteristics of small size, high breaking height, short arcing, and anti vibration
This circuit breaker can be installed vertically or horizontally
This circuit breaker cannot be reversed, that is, only 1, 3, and 5 are allowed to be connected to the power line, and 2, 4, and 6 are allowed to be connected to the load line
Circuit breakers are suitable for isolation, represented by the symbol: one/x
This circuit breaker product complies with the following standards
IEC60947-1 and GB14048.1-2006 General Principles
IEC60947-2 and GB14048.2-2008 Low Voltage Circuit Breakers and Appendix B Circuit Breakers with Residual Current Protection
IEC60947-4-1 and GB14048.4-2003 Low voltage electromechanical contactors and motor starters
