THE PRODUCT APPLICATION
CLBM3 series plastic case circuit breaker(hereinafter referred to as circuit breaker) is one of the new circuit breakers developed by our company with internationaladvanced design and manufacturing technology.Its rated insulation voltage is 1000V, which is suitable for the circuitwith ac 50Hz, rated working voltage of 1000V and below, rated working current of 630A, for infrequent conversion andinfrequent starting of the motor.Circuit breaker with overload, short circuit, protection function, can protect the line,power equipment from damage.
The circuit breaker has the characteristicsof small volume, high breaking, short arc (some specifications zero arc), anti- vibration and so on.
The circuit breaker can be installedvertically (i.e. vertically) or horizontally (i.e. horizontally).
This circuit breaker can not be reversedinto the line, that is, only 1, 3, 5 can be connected to the power line, 2, 4,6 to the load line.
This circuit breaker is suitable forisolation (but different from isolation switch).
