FD62T125 - 125Amp Trip Unit Description
FD62T125 - 125Amp Trip Unit
The Siemens FD62T125 is a 125 Amp thermal-magnetic trip unit for compatible FD-frame molded case circuit breakers. When you're servicing a breaker, the trip unit is one of the most important components to match correctly because it determines the breaker’s overload and short-circuit protection settings.
The FD62T125 is built for FD-frame applications and supports breaker setups using line- and load-side lug connections. It accommodates larger conductors, including 6 AWG to 350 kcmil copper wire and 4 AWG to 350 kcmil aluminum wire. Built to last, this Siemens trip unit is a practical choice for maintenance and repair applications where keeping the original breaker setup and ratings consistent is important.
