FD62T150 - 150Amp Trip Unit

FD62T150 - 150Amp Trip Unit

The Siemens FD62T150 is a 150 Amp thermal-magnetic trip unit for compatible FD-frame molded case circuit breakers. The trip unit is a key part of the breaker assembly because it determines the breaker’s overload and short-circuit protection settings. Matching the correct trip unit to the FD frame and amp rating helps keep your breaker operating with the specifications it was built for.

This Siemens trip unit provides thermal protection for overload conditions and magnetic protection for short-circuit events. The FD62T150 is rated for 600 VAC and is used with breaker configurations rated for 22 kAIC at 600V and 35 kAIC at 480V.

Built for FD-frame breaker applications, the FD62T150 supports configurations using line- and load-side lug connections and accommodates larger conductors, including 6 AWG to 350 kcmil copper wire and 4 AWG to 350 kcmil aluminum wire.
