Motor Protection Circuit Breakers

Supernova series motor protection circuit breaker (MPCB) from L&T Electrical & Automation (E&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 & 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.
