The yellow/red colour signals the trip status: red indicates a tripped condition, yellow indicates the mechanism is reset and ready. It snaps onto the front of the breaker or contactor without additional wiring, so the fit decision is purely mechanical — confirm the breaker or contactor is from the SIRIUS S00 frame size, which is the standard for this operator.
