Finder 22.22.8.240.4000 – 22 Series Modular monostable relays

Why Choose the Finder 22.22.8.240.4000 Modular Power Relay?

The Finder 22.22.8.240.4000 is a dependable modular power relay with two normally open contacts, designed for electrical switching, building automation and industrial control applications. As part of the established Finder Series 22 modular relay range, it provides a practical solution for controlling electrical loads through an independent AC control circuit.

Featuring a 240 V AC operating coil and two normally open (2 NO) contacts, this relay enables two switching paths to be operated simultaneously from a single control signal. Its modular design makes it suitable for electrical distribution assemblies, automation panels and building services installations where dependable switching and straightforward wiring are important.

The Finder 22.22.8.240.4000 combines 20 A rated contacts with a compact 35 mm DIN rail mounting format. It is particularly suitable for lighting control, electrical load switching and automation applications requiring a two-pole normally open relay with a mains-voltage AC operating coil.

Reliable Two-Pole Switching for Electrical Control Systems

The Finder 22.22.8.240.4000 operates by energising an electromagnetic coil with a 240 V AC control supply. When the coil is energised, both normally open contacts close, allowing their connected electrical circuits to conduct. When the coil supply is removed, the contacts return to their normally open state. This arrangement allows two electrical switching paths to be controlled together using a single relay.

Finder Series 22 modular relays are designed for electrical installations where dependable operation, compact mounting and convenient integration are essential. The two-contact arrangement makes this model useful for building automation, lighting circuits and industrial control systems, while its DIN rail format supports straightforward installation alongside other modular electrical equipment.

Typical Applications

• Commercial and industrial lighting control systems.
• Building automation and electrical management installations.
• Electrical distribution boards and modular control assemblies.
• Industrial machinery and equipment switching circuits.
• Remote electrical load switching.
• Two-pole switching of appropriately rated electrical circuits.
• Control panels for building services equipment.
• Automation systems requiring a 240 V AC relay coil.
