VM3 series plastic case type circuit breakers (hereinafter referred to as circuit breakers) have a rated insulation voltage of 800V, suitable for AC 50H, rated working voltage of 690V and below, and rated working current to 800A for infrequent conversion and infrequent motor starting (CBRM3-800 has no motor protection type) for use. The circuit breaker has overload, short-circuit and under-voltage protection functions, which can protect the circuit and power supply equipment from damage. The product has three adjustable delay functions of 0.8×In, 09×In, and 1.0×In, respectively.

The circuit breaker can be installed vertically (ie vertical installation) or horizontally (ie horizontal installation).
