The E.NEXT miniature circuit breaker (MCB) is rated for single-pole (1P) installation on a standard DIN 35mm rail. It provides overload and short-circuit protection for low-voltage networks at a rated current of 20A, with a short-circuit breaking capacity of 4.5kA. The Type C tripping curve is suited to circuits supplying loads with moderate inrush currents, such as motors or transformers.

Rated at 230/400V for indoor use, this MCB carries an IP20 protection rating. Contact terminals accept a tightening torque of 3Nm. It is manufactured in the EU.
