SS1 series molded case circuit breakerDetailed product description：

The SS1 series molded case circuit breaker is a new type of circuit breaker developed by Beijing People's Electric Appliance Factory using international advanced design and manufacturing technology. Its rated insulation voltage is AC690V, suitable for infrequent switching and motor starting in circuits with AC 50Hz, rated working voltage AC690V and below, and rated working current up to 800A. Circuit breakers have short-circuit, overload, and undervoltage protection functions, which can protect the circuit and power equipment from damage.
[SS1 series circuit breakers comply with standards]

[Model meaning]
SS1-225 M/3 3 2 8 2 P 125A AC230V
That is, the SS1 series shell frame has a rated current of 225A and a maximum short-circuit breaking capacity of M standard type three pole plastic case circuit breaker. It uses a compound release (overload long delay+short circuit short delay), with a rated working current of 125A, and accessories with auxiliary contacts and alarm contacts for motor protection. It adopts an AC230V electric operating mechanism and is wired in front of the board.
[Operating Environment]
