WPM1 series moulded case circuit breaker(herein after called circuit breaker)is one of our new type circuit breakers, which adopts international advanced design and manufactural technology, it can be divided into L-type (standard type), M-type (higher breaking type), H-type (current limiting type) according to the rated ultimate short circuit breaking capacity (Icu). With the features of small and compact, high breaking capacity, short arcing-over distance, anti-vibration, the circuit breaker is used popularly on land and marine products, they are applied for the power distribution network of AC 50Hz,rated insulation voltage 800V (WPM1-63 to 500V), rated working voltage 690V(WPM1-63 to 400V) and below, rated current up to 1600A, it can be used to distribute electric power and protect power equipment against overload, short circuit, undervoltage etc, It also takes protective effect when motors infrequently start and protecting against overload, short circuit and lacking voltage. In the series, frame ranging from 63-630A three-pole product also comes with a transparent cover, it is convenient for customer to observe the product operation.
The circuit breaker can be installed vertically, or horizontally. This product complies with standard of IEC60947-2, GB14048.2.

WPM9 Series circuit breakers is new generation breaker.It isapplied for the distribution network of AC 50 Hz, rated insulation voltage 690V, rated working voltage up to 690V, rated cuurent up to 800A. It can distribute power, protect the circuit and power supply devices from the damage of overload, short circuit and under voltage, etc.
This series circuit breaker feature small volume, high breaking capacity and short arcing. It can be installed vertically (namely vertical installation) and also installed horizontally (namely horizontal installation).
It complies with standards of IEC60947-2.

WPM9RE Series circuit breakers is new generation electronic adjustable breaker.It isapplied for the distribution network of AC 50 Hz, rated insulation voltage 690V, rated working voltage up to 690V, rated cuurent up to 800A. It can distribute power, protect the circuit and power supply devices from the damage of overload, short circuit and under voltage, etc.

WPM9T/A, WPM9RT Series circuit breakers is new generation thermal magnetic adjustable breaker.It isapplied for the distribution network of AC 50 Hz, rated insulation voltage 690V, rated working voltage up to 690V, rated cuurent up to 800A. It can distribute power, protect the circuit and power supply devices from the damage of overload, short circuit and under voltage, etc.
