Power (P) and Harmonic (H) Trip Unit without 24 Vdc Power Supply at F1 and F2

The P and H trip units were designed to be used with the external 24 Vdc power supply. The large LCD display requires too much current to be powered by current flow through the circuit breaker. The P and H trip units do have a voltage power supply which will power the trip unit with 100 Vac or more between two phases or phase to neutral. The standard configuration for the voltage probes inside the circuit breaker is at the bottom connections. If the circuit breaker was open in a top fed application, there would be no voltage at the bottom of the circuit breaker and the trip unit would not be powered.

  • Provides fault protection for LSIG functions.

  • Provides LED trip indication (powered by an onboard battery).

NOTE: Ground-fault push-to-trip button works for testing ground fault if the trip unit is powered by the voltage power supply. The ground-fault push-to-trip is also functional if a service interface, a hand-held test kit, or a full-function test kit is powering the trip unit.
