B75TU2 — Single-phase 230 V → 230 V
Designed especially for residential installations where equipment such as air-source heat pumps, air-conditioning systems and other loads require a neutral conductor that is not available from the existing supply. The B75 family creates this neutral point so the equipment can receive the required supply.
Its design is particularly suited to residential environments: quiet operation and low energisation inrush current, reducing the risk of nuisance tripping of the circuit breaker. The IP23 version is intended for indoor installation in a protected environment.
