3HM1 (CM1) series plastic casing type breaker (hereinafter referred to as the breaker), the company is comprehensive adopt international advanced technology, design and development of new type breaker one. Its rated voltage insulation 800V, suitable for AC 50Hz, rated voltage to 690V, rated current to  CM1-100A, 225A, 400A, 630A, 800A, 1000A, 1250A, 1600A
630A power distribution networks circuit to distribution electricity and protecting circuits and circuit and power equipment from overload, short-circuit, owe voltage failure of damage. Also can be used as a motor starting and overload less frequent, short-circuit, owe voltage protection.
According to its rated limit short circuit breaker's height, broken ability points into s-type (standard), H (higher type), R type (limited flow type) three categories. This circuit breaker with small size, high, fly arc break points short, and other features, is the ideal product user. Circuit breaker perpendicular installation (namely vertical loading) circuit breakers product standards: Conform to IEC60947-2, GB14048.2
