Scope of application

3TM1L series leakage circuit breaker (hereinafter referred to as circuit breaker), is to adopt the international advanced design and manufacturing technology development, the development of new type of circuit breaker. Its rated insulation voltage is 690 v, suitable for ac 50 hz, rated voltage 400 v, rated current 630 a circuit for infrequent conversion. Circuit breaker with overload, short circuit and low voltage protection device, protect circuit and power equipment from being damaged. Can provide indirect contact protection for personal circuit breaker at the same time, also over current protection can not be detected long-standing ground-fault protection. Circuit breaker tm1 appearance size, installation size and 3 series circuit breaker with shell frame completely same grade products.

Circuit breaker according to the rated short circuit breaking capacity limit (Icu) of high and low are divided into: M type (standard), H (high marks broken) category. The circuit breaker has small volume, high breaking, short arcing and vibration resistance, etc.

• The circuit breaker can be installed vertically (that is, vertical pack), can be installed horizontally (that is, the horizontal loading).

• The circuit breaker with isolation function

• The circuit breaker products perform the following standards:

> And GB/T14048.1 IEC60947-1 general rules

> IEC60947-2 and GB/T14048.2 low-voltage circuit breaker and appendix B circuit breaker with residual current protection
