Product Information
Full details
This Schneider Electric Acti9 iCT 20A contactor is ideal for electricians and system integrators needing reliable remote switching for lighting, small motors, and HVAC. Its key benefit is the zero-crossing technology, which protects loads and extends the contactor's life, especially for LED applications. A caveat is its maximum operating speed of 6 operations per minute, making it unsuitable for high-frequency switching tasks.

FAQs
What is the maximum load this contactor can handle?
The Schneider Electric Acti9 iCT contactor is rated for a maximum of 20A for AC-7a/AC-7b applications.
What is the advantage of zero-crossing technology?
Zero-crossing technology switches the load on or off precisely at the zero voltage point of the AC waveform. This significantly reduces electrical stress and noise on the load, making it ideal for sensitive electronics like LED lighting and extending their lifespan.
Can this contactor be used for DC loads?
No, this contactor is designed specifically for AC loads and AC control voltages (250 VAC operating, 230 VAC control). It is not suitable for DC applications.
How is this contactor mounted?
The Acti9 iCT contactor is designed for easy mounting on a standard 35mm DIN-rail.
What is the lifespan of this contactor?
The electrical lifespan of this contactor is rated for 5 million cycles under normal operating conditions.
Can I manually operate this contactor without power?
This specific model (A9C15030) does not feature a manual override switch for hand operation. It requires the control voltage to activate.
What protection rating does this contactor have?
The contactor has an IP20 protection rating in its open state and IP40 when installed in a suitable enclosure.
Troubleshooting
Contactor does not switch on when control voltage is applied.
Verify that the control voltage supplied to the coil terminals is within the rated 230 VAC range. Check wiring connections for proper contact and ensure the control circuit is active.
Contactor hums loudly or vibrates excessively.
Ensure the control voltage is stable and within the specified 230 VAC tolerance. Check for any foreign objects or obstructions around the contactor mechanism. Ensure it is securely mounted on the DIN rail.
Overheating of the contactor or connected wires.
Confirm that the load current does not exceed the 20A rating. Ensure all connections are tight. Verify that the connected load is compatible with the contactor's specifications (AC-7a/AC-7b).
Intermittent operation or failure to make/break contact.
Inspect the power and load terminals for loose connections or signs of arcing. Check for excessive switching frequency, which might be beyond the operational limits (6 operations/min).
Pros and Cons
Pros
- Reliable switching for LED lighting due to zero-crossing technology.
- Durable design with a long electrical lifespan of 5 million cycles.
- Compact, modular design for easy integration into electrical panels via DIN-rail mounting.
- Low control voltage requirement (230 VAC) simplifies wiring.
- Suitable for a range of applications including lighting, small motors, and HVAC.
Cons
- Limited to a maximum of 6 operations per minute, not suitable for high-frequency switching.
- Single Normally Open contact limits complex switching arrangements.
- Requires specific AC control voltage (230 VAC), not universally compatible with DC control.
- IP20 rating in open state requires installation within an enclosure for better protection.
Setup, Compatibility & Care
Setup: The Acti9 iCT contactor is designed for easy DIN-rail mounting. Ensure the power and control circuits are de-energized before installation. Connect the load wires to the power terminals and the control wires to the coil terminals, adhering to the specified voltage ratings (250 VAC operating, 230 VAC control).
Compatibility: This contactor is compatible with standard AC power systems (250 VAC) and AC control circuits (230 VAC). It is suitable for loads like LED lighting (up to 3700 VA), fluorescent lamps (up to 3700 VA), and small motors within its 20A rating.
Care: Keep the contactor clean and free from dust and moisture, especially if installed in environments with less than IP40 protection. Ensure adequate ventilation around the unit. Periodic visual inspection for any signs of damage or wear is recommended, although extensive maintenance is typically not required due to its high electrical lifespan.
