The RubberBox RUB185H3 is a 63A 415V three-phase (3PH+N+E) power distribution box designed to split a single supply into two 32A three-phase outputs. It provides a straightforward way to take a higher-rated feed and distribute it across smaller circuits while keeping the setup contained and easy to handle.

The unit is fitted with a 63A 415V 3PH+N+E appliance inlet and delivers power via 2 × 32A 415V 3PH+N+E sockets. A 63A 30mA 4P RCD provides overall earth leakage protection, with 2 × 32A TP MCBs in place to protect each outgoing circuit.
