FD62T070 - 70Amp Trip Unit Description
FD62T070 - 70Amp Trip Unit
The Siemens FD62T070 is a 70 Amp thermal-magnetic trip unit designed for use with compatible FD-frame molded case circuit breakers. For breaker maintenance and service work, choosing the correct trip unit is critical because the amp rating, frame compatibility, trip characteristics, and electrical ratings all need to match your breaker assembly.
This Siemens trip unit provides thermal-magnetic protection, helping the breaker respond to both overload conditions and short-circuit events. It is rated for 600 VAC with interrupting ratings of 22 kAIC at 600V and 35 kAIC at 480V when installed in the proper FD-frame breaker configuration.
The FD62T070 is designed for FD-frame applications and supports breaker configurations using larger conductor ranges, including 6 AWG to 350 kcmil copper wire and 4 AWG to 350 kcmil aluminum wire.
