ICT Contactor 25A 3 NO 230/240V AC

The Schneider Electric Acti9 iCT A9C21833 is a modular contactor with 3 poles and 25 A, equipped with 3 normally open contacts (3 NO) and a control voltage of 220-240 V AC at 50 Hz. Designed for manual and remote control of electrical loads, it allows you to manage lighting, heating, ventilation, and small motor circuits from residential, tertiary, and commercial electrical panels.

This contactor from the Acti9 iCT range is designed for mounting on a 35 mm DIN rail and features an integrated manual override, making it easy to automate loads while also allowing local operation when testing, maintenance, or direct control is required.

3-pole 25 A modular contactor

The A9C21833 features 3 poles with normally open contacts. Its rated operational current is 25 A in AC-7A category, suitable for slightly inductive loads and common applications in domestic and tertiary installations.

For motor loads classified as AC-7B, the rated operational current is 8.5 A. This distinction makes it possible to select the correct contactor according to the type of load to be controlled.

• AC-7A rated current: 25 A.
• AC-7B rated current: 8.5 A.
• Number of poles: 3P.
• Contact configuration: 3 NO.
• Rated operational voltage: 400 V AC at 50 Hz.
• Control circuit voltage: 220-240 V AC at 50 Hz.

Manual and remote control

One of the main features of this Acti9 iCT version is the combination of remote control and manual operation. The contactor can be electrically controlled via its control coil and also operated locally from the device itself.

This solution is especially useful in automated installations, allowing loads to be controlled by timers, management systems, control signals, or other compatible devices, while still retaining the option of manual intervention.

The unit also includes a mechanical contact position indicator, making it easy to visually check the status of the contactor.

Applications of Schneider Acti9 iCT

Schneider Electric designs Acti9 iCT modular contactors for controlling different AC loads. The A9C21833 reference can be used, among other applications, for:

• Lighting circuit control.
• Electrical heating systems.
• Ventilation equipment and circuits.
• Small motors, such as fans and mixers.
• Automation of electrical loads from distribution boards.
• Load control and management circuits.

The contactor is compatible with Acti9 control auxiliaries, allowing you to expand automation options and adapt the electrical panel to the needs of each installation.

Modular DIN rail mounting

The A9C21833 is designed to be clip-mounted on a 35 mm symmetrical DIN rail. Its modular format occupies 4 modules of 9 mm, equivalent to 36 mm in width, making it easy to integrate alongside other Schneider Electric Acti9 modular devices.

Its compact dimensions help make efficient use of the available space inside the electrical panel:

• Height: 81 mm.
• Width: 36 mm.
• Depth: 60 mm.
• Mounting: 35 mm DIN rail.
• Format: 4 modules of 9 mm.
• Color: white.

Control coil consumption

The control coil operates at a voltage of 220 to 240 V AC at 50 Hz. The holding consumption is 4.6 VA, while the inrush consumption reaches 34 VA. The maximum power indicated by the manufacturer is 1.6 W.

• Holding consumption: 4.6 VA.
• Inrush consumption: 34 VA.
• Maximum power: 1.6 W.
• Control signal type: maintained.

High electrical and mechanical durability

The Schneider Electric Acti9 iCT contactor is designed to withstand a high number of switching operations. Its mechanical durability reaches 1,000,000 cycles, providing a long service life in installations where loads are switched frequently.

Electrical durability depends on the utilization category and the connected load:

• AC-7A electrical durability at 25 A: up to 100,000 cycles.
• AC-7B electrical durability at 8.5 A: up to 30,000 cycles.
• Specified switching frequency: up to 100 operations per day.

Electrical protection and insulation

The device has a rated insulation voltage of 500 V AC and an impulse withstand voltage of 4 kV. Its degree of protection is IP20 when installed according to Schneider Electric’s specified conditions, and it can reach IP40 in an enclosure.

These features make it suitable for use inside properly designed and protected distribution boards.

Compliant with IEC/EN 61095

The Schneider Electric A9C21833 modular contactor complies with IEC/EN 61095, applicable to electromechanical contactors for household and similar uses. This makes it a suitable solution for automation and switching of loads in residential and tertiary installations.
