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 breaker is a new generation of breaker.
This breaker is applied for the distribution network of AC 50/60Hz, rated insulation voltage 800V, rated working voltage
up to 690V, rated working current up to 1250A, which is for electric energy distribution, circuit protection, protection power supply facility from destroying by the fault of overloading, short circuit and undervoltage, meanwhile it is also used for protection from unfrequent starting, over loading, short circuit and undervoltage of the motor.
This breaker has such characteristics as high short circuit interrupting capacity, short arcing and etc., which is a ideal product for users. This breaker can be installed vertically (upright), and also horizontally
This breaker comply with standard IEC/EN 60947-2.

WPM9DA,WPM9SA,WPM9EA series circuit breaker is a new generation of breaker.
This breaker is applied for the distribution network of AC 50/60Hz, rated insulation voltage 800V, rated working voltage
up to 690V, rated working current up to 1250A, which is for electric energy distribution, circuit protection, protection power supply facility from destroying by the fault of overloading, short circuit and undervoltage, meanwhile it is also used for protection from unfrequent starting, over loading, short circuit and undervoltage of the motor.
This breaker has such characteristics as high short circuit interrupting capacity, short arcing and etc., which is a ideal product for users. This breaker can be installed vertically (upright), and also horizontally
