Exotronic - 50A - 2-Pole DC Circuit Breaker (MCB) (Pack of 6)

Exotronic 50A 2-Pole DC Circuit Breaker (MCB) - Pack of 6

600V-Rated DC Protection for Solar, Battery and Off-Grid Systems

This pack contains six identical Exotronic 50A 2-Pole DC Circuit Breakers (MCB), giving you enough breakers on hand to protect multiple circuits or keep spares for future expansion. Each breaker is a double-pole, non-polarised DC breaker rated to 600V DC, designed for caravan, marine, industrial and off-grid photovoltaic (PV) systems. Every breaker in the pack shares the same 50A rating, sized to protect a DC load or array of that rating while maintaining stable power flow.

Using thermo-magnetic trip technology, each breaker disconnects the circuit during an overload or short circuit to help protect cabling and equipment. The non-polarised design allows safe bidirectional current flow, removing the risk of directional wiring errors and suiting 12V, 24V and 48V battery systems as well as higher-voltage solar arrays.

Each breaker mounts to a standard DIN rail and includes a clear visual indicator to show isolation status at a glance. The flame-retardant thermoplastic body is built to IEC/EN 60947-2 standards for use in demanding Australian conditions, including off-grid sheds, camper trailers and marine engine bays.
