Product Information
Full details
The Finder 22.32.0.024.4340 is a modular installation contactor designed for electrical control applications. It is ideal for professionals managing power circuits that require reliable switching up to 25A. While its compact 17.5mm width saves space, users should ensure their specific application voltage aligns with its 24V AC/DC coil rating. This device features two normally open contacts, an Auto-On-Off switch, and LED status indication, simplifying installation and monitoring.

FAQs
What is the maximum voltage the contacts can switch?
The rated operating voltage for the contacts is between 250V and 440V AC, depending on the specific application and load type.
Can this contactor be used with a 12V or 48V control system?
No, this contactor is specifically designed for a 24V AC/DC coil voltage. Using other voltages will likely result in malfunction or damage.
Does this contactor have Normally Closed (NC) contacts?
No, this model (22.32.0.024.4340) features two Normally Open (NO) contacts only.
How do I use the Auto-On-Off switch?
The slider allows you to manually switch the contactor to 'On' or 'Off' for testing or maintenance, overriding the electrical control signal. Set it to 'Auto' to return to normal electrical control.
What is the significance of the AgSnO2 contact material?
Silver tin oxide (AgSnO2) is used for its good conductivity and resistance to electrical erosion, providing a longer lifespan and more reliable switching performance compared to some other contact materials.
What type of DIN rail is required?
It requires a standard EN 60715 TH35 DIN rail for mounting.
What is the IP rating and what does it mean?
The IP rating is IP20. This means it is protected against solid objects larger than 12.5mm (like a finger) but offers no protection against water. It must be installed in an environment protected from moisture and dust.
Troubleshooting
Contactor does not energize when control voltage is applied.
Verify the control voltage supply is indeed 24V AC or DC and correctly connected to the coil terminals. Check for any breaks in the control wiring. Ensure the Auto-On-Off switch is in the 'Auto' position.
Contacts remain closed or open when they should not.
Check the coil voltage supply. If the coil is energized but contacts are not switching correctly, there may be an internal issue. Ensure the load connected does not exceed the 25A rating or voltage limits.
LED indicator is not lit.
Confirm that the coil is receiving the correct 24V AC/DC supply. If the supply is present and correct, the LED may be faulty, though the switching function might still be operational.
Overheating of the contactor.
Ensure the connected load current does not exceed the 25A rating. Verify that the ambient temperature is within the operating range (-20 to 50 °C). Check for loose connections which can cause increased resistance and heat.
Pros and Cons
Pros
- Compact 17.5mm width saves significant panel space.
- Versatile 24V AC/DC coil voltage.
- Integrated Auto-On-Off switch for manual control.
- Clear LED status indicator for easy monitoring.
- Durable AgSnO2 contact material for longevity.
- Simple DIN rail mounting.
Cons
- Only offers Normally Open (NO) contacts; no Normally Closed (NC) options available.
- Fixed 24V AC/DC coil voltage may not suit all control systems.
- Maximum operating voltage of 250-440V requires careful consideration for load matching.
- IP20 degree of protection requires installation in a protected environment.
- Limited load types specified (e.g., incandescent, fluorescent lamps); suitability for other loads must be verified.
Setup, Compatibility & Care
Setup:
- Ensure the power supply is disconnected before installation.
- Mount the contactor onto a standard EN 60715 TH35 DIN rail by snapping it into place.
- Connect the power and control wiring to the appropriate terminals, respecting polarity for the DC portion of the AC/DC coil if applicable.
- Verify wiring against the schematic diagram for your specific application.
Compatibility:
- The coil operates on 24V AC or DC. Ensure your control voltage matches this requirement.
- The contact rating is 25A at 250VAC (or 440V rated operating voltage). Ensure the connected load is within these specifications.
- Designed for use with standard control panels and wiring practices.
Care:
- The contactor has an IP20 rating, meaning it must be installed in an enclosure to protect against dust and accidental contact.
- Periodically inspect wiring connections for tightness.
- Avoid exposing the unit to excessive moisture, dust, or corrosive environments.
- Cleaning should be done with a dry or slightly damp cloth; do not use solvents.
