STM1 series moulded case circuit breaker ( named as MCCB in the following) is a new type breaker which is applied with rated insulating voltage 800V (500V for STM1-63), rated working voltage 400V/415V and used for infrequent exchange and startup in AC (60)Hz condition. The MCCB is of protecting function in overloading, short-circuit, and under voltage situation to protect circuit system and power device from damage.
The MCCB can be devided into L; M; H types according to their rated limit short-circuit breaking capacity.
The MCCB is advantageous for its compact body, high breaking capacity ( some even on flying arc), short arc-casting and superior aseismatic function.
The MCCB has function of insulation.
