GTM2L series earth leakage circuit breaker is one of the new circuit breakers designed and developed by our company. The rated insulation voltage is 800V, which is suitable for ac 50Hz/60Hz, rated operating voltage of 400V and below, and it is used for non-frequent conversion and motor infrequent starting in the circuit with rated working current of 16A to 630A. The circuit breaker has overload, short circuit, leakage protection, undervoltage protection, leakage alarm, alarm, and fire alarm. Circuit breaker belongs to the three phase four wire power supply mode, the action time of the products function has the leakage current, the leakage of action can selective protection, the leakage current value the four digital display, the power of arbitrary two all can work. It can protect the circuit and power equipment from damage, and it can also provide protection for the fire danger if the long-existing ground fault cannot be detected by overcurrent protection.
The circuit breaker has the characteristics of small size, high breaking height, short flying arc (partial specification of flying arc) and vibration resistance.
