42-107430-03 – CIRCUIT BREAKER (60A, DIN RAIL, LUG/LUG)

This DIN rail-mounted circuit breaker goes inside the equipment cabinet (typically in a heat pump or air handler) to provide overcurrent protection. If the internal breaker trips repeatedly or won’t reset, it may need to be replaced. This is the Rheem OEM breaker for equipment that uses a DIN rail-style panel.
