Finder 22.32.0.024.4440 Installation Contactor, 2 NC Contacts, 25A, 24V AC/DC

The Finder 22.32.0.024.4440 is a high-quality modular installation contactor engineered for reliable switching in electrical distribution boards. Designed for standard 35 mm DIN rail mounting, this device provides efficient control for various electrical loads. It features two normally closed (NC) contacts and is built to handle a rated current of 25A, making it a robust solution for managing power in both residential and commercial environments. The unit includes a manual Auto-Off-On switch, an integrated LED indicator, and a mechanical contact position display for easy status monitoring.

Advantages

This contactor offers exceptional operational flexibility through its manual override switch, allowing users to toggle between automatic and manual modes easily. The inclusion of a clear mechanical position indicator and an LED status light ensures that the operational state of the circuit is always visible at a glance. Built with high-grade AgSnO2 contact material, the device provides long-lasting durability and resistance to welding, ensuring consistent performance even under frequent switching cycles. Its modular design allows for seamless integration into standard electrical cabinets, saving space and simplifying installation.

Suitable for

• Switching lighting circuits in residential buildings
• Controlling heating and ventilation systems
• Managing power distribution in commercial electrical installations
• Automated load control in smart home systems

When it may not be suitable

This contactor is not intended for use in environments with high levels of dust, moisture, or corrosive gases, as it carries an IP20 protection rating. It is also not suitable for applications requiring high-frequency switching beyond its rated electrical endurance or for circuits exceeding the specified 400V AC voltage limit.

Key specifications

• Contact configuration: 2 NC (Normally Closed)
• Rated current: 25A
• Coil voltage: 24V AC/DC
• Maximum switching voltage: 400V AC
• Mounting type: 35 mm DIN rail
• Contact material: AgSnO2
• Protection rating: IP20
• Features: Auto-Off-On switch, LED indicator, mechanical position display

How to use

Installation should be performed by a qualified electrician in accordance with local safety regulations. The device is designed to be snapped onto a standard 35 mm DIN rail within an electrical distribution board. Ensure that the coil voltage matches your control circuit (24V AC/DC). Once mounted, connect the load cables to the appropriate terminals. The manual switch on the front allows you to override the automatic control signal if necessary, while the LED and mechanical indicator provide visual confirmation of the contact status during operation.

What to consider before purchase

• Verify that your control system provides a 24V AC/DC signal.
• Ensure the 25A current rating is sufficient for your specific load requirements.
• Confirm that the 2 NC contact configuration meets your circuit logic needs.
• Check that the installation environment is dry and protected from environmental hazards.

Usage recommendations

Regularly inspect the contactor for signs of wear or debris accumulation, especially in environments with high switching frequency. Ensure that all terminal connections are tightened to the manufacturer's specified torque to prevent overheating.
