Motor Protection Circuit Breaker for Safety

The Supernova series motor protection circuit breaker (MPCB) from  Lauritz Knudsen Electrical and Automation seamlessly combines the functions of a moulded case circuit breaker (MCCB) and a thermal overload relay into a singular, highly compact unit. Featuring an adjustable current range dial with a precise maximum/minimum ratio of 1.4 to 1.6, the MPCB can be finely tuned to the rated current of the motor, ensuring optimal protection. This unit is specifically designed to safeguard against short circuits and overload conditions, enhancing the reliability and efficiency of motor operations.

The design of the Supernova series MPCB incorporates overload relay functions within its compact framework, significantly reducing the required installation space and wiring complexity. This integration facilitates a more streamlined panel design, allowing for a reduction in overall panel size. Such design efficiency not only optimises space but also simplifies installation and maintenance processes, making it an ideal solution for diverse industrial applications.
