Product Description
SM1L Series moulded case circuit breaker with earth leakage protection
Keyword:Vertical or Horizontal installation, with leakage current, alarm function;Leakage current tripping fast,
complete accessory and can adjust leakage operating current and time
Application
SM1L series moulded case circuit break with residual current pro-duction. Rated insulation Voltage is 800V. It applies to circuit of AC 50Hz, rated working voltage 400V and rated working Current up to 630A, for infrequent switch over and infrequent start of motor.
With overload,Short Circuit and under-voltage production,it can protect circuits and power-supply equipment from damage, can also be used for production from damage and any potential fire-hazard caused by long Existing earth fault which can not be detected by
over-current production. The value of residual current is selectable.
NB3LE MCB combines the following functions:
b Protection of circuits against short-circuit currents
b Protection of circuits against overload currents
b Control
b isolation
