Product details

Overview

The A9D55740 is a Schneider Acti 9 iDPN Vigi residual current circuit breaker with overcurrent protection (RCBO), rated 40 A at 415 V AC, 3-pole, with a 6 kA breaking capacity conforming to EN/IEC 61009-2-1. It integrates earth-leakage protection (Type AC) and thermal-magnetic overcurrent protection in a single 10-module (9 mm pitch) clip-on unit. This part is in active production.

Schneider lists the A9D55740 as an active, in-production part with no announced end-of-life. For a BOM fill or line-down replacement, an RFQ is the fastest path to confirm current lead time and available quantity. The part carries an 18-month warranty from Schneider.
