AF, ampere frame: The peak fault-current withstand capability of the circuit
breaker without mechanical or thermal damage.
LVR, low voltage release: It automatically reconnects the circuit when power
is restored after a temporary loss. This is provided to auxiliary equipment
critical to ship propulsion equipment, where automatic restarting would not
pose hazard.
LVP, low voltage protection: It will permanently shut down the circuit if power
is lost, and will not start again by itself when the power is restored. All large
motors drawing very high starting current for long time use LVP.
Red-V, reduced-volt
