Product Information

Full details

The Schneider Electric Acti9 iCT modular contactor (A9C20137) is designed for professionals managing remote control applications in electrical systems, HVAC, and small motor switching. Its key benefit is reliable remote operation with 4 normally closed (NC) contacts, enabling robust control circuit management. A potential consideration is its specific 24V AC control voltage, requiring a compatible power source. This contactor offers 25A AC-7a/8.5A AC-7b ratings at 400V AC, a long electrical lifespan, and easy DIN rail installation.

Extended Product Information

FAQs

What is the specific control voltage for this contactor?

The Schneider Electric Acti9 iCT modular contactor (A9C20137) requires a 24V AC control voltage.

How many normally closed contacts does this model have?

This model features 4 normally closed (NC) contacts.

What is the maximum AC load current rating?

It has a rating of 25A for AC-7a (resistive loads) and 8.5A for AC-7b (small motor loads) at 400V AC.

How is this contactor mounted?

It is designed for standard 35mm DIN rail mounting and occupies 4 modules (9mm each).

What is the electrical lifespan of this contactor?

The contactor has an electrical lifespan of 100,000 cycles for AC-7A/AC-1 applications.

Is this product environmentally certified?

Yes, it is recognized as a Better World Product with Green Premium verification.

Can this contactor be used for DC control circuits?

No, this contactor is specifically designed for AC control voltage (24V AC) and AC load applications.

Troubleshooting

Contactor does not energize (no click sound)

Verify the 24V AC control voltage is present and correctly applied to the coil terminals. Check for loose wiring connections.

Contactor remains energized when control signal is removed

Ensure there is no residual voltage on the control circuit. Check for short circuits in the control wiring.

Contacts are not switching (load always on or off)

Confirm the control voltage is applied correctly. Check for internal contact failure; if suspected, the unit may need replacement. Verify the load is within the specified AC-7a/AC-7b ratings.

Overheating during operation

Ensure the load current does not exceed the AC-7a (25A) or AC-7b (8.5A) ratings. Verify proper ventilation in the enclosure.

Pros and Cons

Pros

  • Reliable remote switching capabilities with 4 NC contacts.
  • Durable with a long electrical lifespan for AC-7A/AC-1 applications.
  • Space-saving modular design for easy DIN rail installation.
  • Suitable for a range of AC loads including small motors.
  • Environmentally verified as a Better World Product.

Cons

  • Requires a specific 24V AC control power source.
  • AC-7b rating limits its suitability for larger motor loads.
  • Primarily designed for control circuits, not direct high-power distribution.

Setup, Compatibility & Care

Setup:

  1. Mounting: Secure the contactor onto a standard 35mm DIN rail within your control panel.
  2. Wiring: Connect the control circuit to the designated 24V AC control terminals. Ensure correct polarity if applicable (refer to wiring diagrams).
  3. Load Wiring: Connect the power circuit to the main output terminals according to the required configuration (4 NC).
  4. Verification: Double-check all connections before applying power. Ensure the control voltage matches the 24V AC requirement.

Compatibility:

  • Control Voltage: Strictly requires a 24V AC power source for the coil.
  • Enclosure: Suitable for standard electrical enclosures with DIN rail mounting.
  • Load Types: Best suited for AC-7a (resistive loads) and AC-7b (small motor loads) up to its rated current.

Care:

  • Environment: Operate within specified temperature and humidity ranges to ensure longevity. Keep the unit clean and free from dust accumulation.
  • Inspection: Periodically inspect wiring for signs of wear or damage. Ensure mechanical operation is smooth.
