SJKM1E-250/3300 Electronic Plastic Shell Circuit Breaker

Scope of application
SJKM1E electronic plastic shell circuit breaker (hereinafter referred to as the circuit breaker) is suitable for AC 50Hz (or 60Hz), with a rated insulation voltage of 800V, a rated working voltage of 400V and below, and a rated working current up to 800A. It is used for infrequent switching and motor starting in circuits. The circuit breaker has overload long delay inverse time limit, short circuit short delay inverse time limit, short circuit short delay fixed time limit short circuit instantaneous and undervoltage protection functions, as well as residual current protection (optional), phase loss protection function (optional), which can protect the line and power equipment from damage. The protection characteristics of the circuit breaker are complete and accurate, which can improve power supply reliability and avoid unnecessary power outages. The "Z, B" type control has a communication interface and can perform "four remote" to meet the requirements of the control center and automation system
Circuit breakers are divided into two types based on their rated ultimate short-circuit breaking capacity: M-type (higher breaking type) and H-type (high breaking type). This circuit breaker has the characteristics of small size, high breaking capacity, short arcing and anti vibration
Circuit breakers can be installed vertically or horizontally
The circuit breaker has an isolation function, and its corresponding symbol is: x
The 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
