L&T’s Supernova series motor protection circuit breaker (MPCB) integrates functions of a 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 & overload. Also the compact size of the MPCB, including overload relay functions, enables a smaller installation area with less wiring space, for a reduction in panel size.
