Supernova series motor protection circuit breaker (MPCB) from Land T Electrical and Automation (E and A) integrates functions of MCCB and thermal overload relay into a highly compact single unit. Equipped with a wide range current adjustment dial (with maximum/minimum ratio of 1.4 to 1.6), the MPCB easily adjusts to match the rated current of the motor for optimum protection. MPCB provides protection against short circuit and overload. The compact size of the MPCB, including overload relay functions, also enables a smaller installation area with less wiring space for a reduction in panel size.
