Scope of Application

TXCM1LE Molded Case Circuit Breaker is one of the new breakers which have been designed and developed by the company using international advanced technology. Suitable for the circuits of AC 50Hz, rated voltage of 400V, rated current of 16A to 800A.

Its main function is to provide indirect contact protection for personal electric shock of fatal danger. Rated residual operating current does not exceed residual current operated circuit breaker of 0.03A when other protection measures are invalid, also can provide supplementary protection for direct contact, but not as the only direct contact protection. At the same time, CM1LE MCCB can also prevent electrical fire caused by the contact fault current. And CM1LE MCCB can protect overload and short circuit of the circuits, can also be used for infrequent conversion of the circuits.

TXCM1LE MCCB can be mounted vertically (upright) or horizontally (transverse).

Meet the standards: GB 14048.2, IEC 60947-20
