ICT Contactor 25A 2 NO+2 NC 230/240V AC

The Schneider Electric Acti9 iCT A9C20838 is a modular contactor rated at 25 A and 4 poles, equipped with 2 normally open contacts (2 NO) and 2 normally closed contacts (2 NC). It is designed for remote control and switching of electrical circuits for lighting, heating, ventilation, and small motors, offering a compact solution for residential, commercial, and tertiary electrical panels.

Reference A9C20838 includes a 220-240 V AC control coil and offers a rated operational current of 25 A in AC-7A category and 8.5 A in AC-7B category. Its 36 mm modular width makes it easy to install on DIN rail alongside Acti9 protection and auxiliary devices.

4-pole contactor with 2 NO + 2 NC

The Acti9 iCT A9C20838 features a 4-pole configuration made up of two normally open contacts and two normally closed contacts. This arrangement allows simultaneous control of circuits that require different switching behaviors from the same control signal.

When the coil changes state, the NO and NC contacts switch simultaneously, so the contactor can be integrated into automation systems, signaling systems, lighting circuits, or installations where opening and closing different loads must be combined.

25 A for electrical load control

Schneider Electric specifies this contactor with a rated operational current of 25 A in AC-7A category, corresponding to domestic and similar slightly inductive loads, and 8.5 A in AC-7B category, intended for certain motor loads.

Its rated operational voltage is 400 V AC, while the rated insulation voltage reaches 500 V AC. It also has an impulse withstand voltage of 4 kV.

220-240 V AC control coil

The A9C20838 contactor is operated by a 220 to 240 V AC control coil. This control voltage makes it easy to integrate with thermostats, time switches, relays, building management systems, and other compatible automation devices.

The control signal is maintained, so the contactor remains energized while the coil is powered.

Applications in lighting, heating, and ventilation

The Schneider Electric Acti9 iCT is specifically designed for remote switching of loads commonly used in homes, shops, offices, and tertiary buildings. Schneider Electric indicates compatibility with lighting, heating, and ventilation applications, as well as small motors.

• Lighting circuit control.
• Electrical heating systems.
• Ventilation and air conditioning.
• Fans.
• Mixers and small motors.
• Automation and remote control circuits.

Compatible with Acti9 auxiliaries

The contactor is compatible with Acti9 range control auxiliaries, allowing the functions of the electrical panel to be expanded with elements for timing, control, signaling, or automation, depending on the installation requirements.

The iCT contactors up to 25 A also feature a clip-on system for electrical and mechanical connection with compatible auxiliaries, simplifying assembly of the unit.

Mechanical position indicator

The front of the device includes a mechanical contact position indicator. This indication makes it possible to visually check the contactor status during installation, commissioning, troubleshooting, or maintenance tasks.

Modular DIN rail mounting

The A9C20838 is designed for clip-on installation on a 35 mm symmetrical DIN rail. Its design occupies four 9 mm modules, equivalent to a total width of 36 mm, making it easy to integrate into modular panels.

• Width: 36 mm.
• Height: 81 mm.
• Depth: 60 mm.
