Overview
The A9C24740 is a Schneider Acti 9 iCT remote control switch, 3-pole, rated for 40 A switching current and a 240 V AC coil supply. It is designed for lighting control in residential and small commercial distribution boards, complying with IEC/EN 61095. The module clips onto a DIN-rail, measures 54 mm wide by 85 mm high by 60 mm deep, and carries an IP20 rating for in-cabinet installation.
This remote control switch uses a maintained-coil control signal — the coil holds the contacts closed as long as the 240 V AC control voltage is present, and drops out when the signal is removed. The 40 A switching current covers resistive and inductive lighting loads, and the 3-pole configuration allows simultaneous switching of three phases or three independent circuits. Rated for 50 Hz AC networks, the switch includes a desynchronized neutral pole technology that ensures the neutral opens after the phases and closes before them, improving safety during maintenance. The action indicator on the front provides local visual confirmation of the contact state.
Applications
The A9C24740 is intended for lighting control in residential and small commercial buildings, typically installed in Acti 9 distribution boards. It is suited for group control of LED lighting — Schneider notes that LED lighting should be controlled as a group to avoid flicker from individual switching. The maintained-coil design makes it appropriate for time-clock or building-management-system driven on/off schedules.
The A9C24740 is an active Schneider product with no announced end-of-life. It carries IEC/EN 61095 certification, tropicalisation treatment conforming to EN 60947-4-1 and EN 61095, and pollution degree 2 rating for normal industrial environments. Standard warranty is 18 months from date of manufacture.
