FD63T150 - 150Amp Trip Unit Description
FD63T150 - 150Amp Trip Unit
Choosing the right circuit breaker for a commercial or industrial electrical system is about more than matching the amperage. You need a breaker that provides dependable protection, fits the application, and performs when the electrical system is under stress. The FD63T150 Siemens circuit breaker is a 150 Amp, 3-pole molded case circuit breaker designed to provide reliable overcurrent protection for three-phase electrical distribution systems where safety and performance are essential.
As part of the Siemens SENTRON FD frame family, the Siemens FD63T150 150 amp circuit breaker is built for applications requiring a 600V molded case circuit breaker with dependable fault protection. This breaker uses a thermal magnetic trip unit that combines two important protection functions into one device. The thermal trip helps protect against long-lasting overload conditions, while the magnetic trip responds quickly to short-circuit events.
