Single-phase 230V 32A reversing box - without socket
This single-phase inverter box (230 V / 32 A) combines two 32 A circuit breakers, a 63 A / 300 mA residual current device (Type A) and a 63 A four-pole modular inverter (4 poles). The unit is delivered assembled in a robust, ready-to-use enclosure.
It allows you to easily switch between two power sources (mains and backup/inverter) while ensuring complete protection for your installation. Ideal for domestic or commercial use, it combines safety, compactness and ease of use.
The "Pre-wiring" option: The addition of 2 × 2 m of XVB 3G6 cable, pre-wired by us, radically simplifies the connection between the box and your UPS.
