Finder 22.23.8.230.4000 – 22 Series Modular monostable relays

Why Choose the Finder 22.23.8.230.4000 Modular Installation Relay?

The Finder 22.23.8.230.4000 is a compact and reliable 20 A modular installation relay designed for electrical load switching in residential, commercial and industrial control systems. As part of the Finder Series 22 modular monostable relay range, this electromechanical relay features a 230 V AC operating coil and two contacts arranged as 1 normally open (NO) and 1 normally closed (NC), providing flexible switching and change-of-state control for electrical installations.

Designed for mounting onto standard DIN rails, the Finder 22.23.8.230.4000 combines dependable switching performance with a space-saving modular housing. Its slim 17.5 mm width occupies approximately one modular space in an electrical distribution board. The relay incorporates a manual test button, mechanical indication and screw terminal connections, simplifying installation, commissioning and maintenance in building automation and electrical control applications.

With a 20 A rated contact current, a 230 V AC coil supply and a maximum switching voltage of 400 V AC, the Finder 22.23.8.230.4000 is suitable for switching compatible lighting circuits, heating equipment, ventilation systems and general electrical loads. Its silver tin oxide (AgSnO₂) contacts, IP20 protection rating and 35 mm DIN rail mounting make it a practical solution for electrical distribution boards, industrial control panels and building management systems.

Reliable Two-Pole Switching for Electrical Control Systems

Modular installation relays such as the Finder 22.23.8.230.4000 enable electrical loads to be controlled through a separate operating circuit. When the 230 V AC coil is energised, the relay's internal electromechanical mechanism closes the normally open contact and opens the normally closed contact. When the coil supply is removed, both contacts automatically return to their original positions. This arrangement allows complementary switching functions to be performed using a single control signal.

The Finder Series 22 is designed for electrical installers, panel builders and automation engineers requiring reliable switching within compact electrical enclosures. Its 20 A contact rating, durable silver tin oxide contacts and 1 NO + 1 NC configuration make it suitable for building automation, lighting control and electrical distribution applications. The integrated test button and mechanical indication simplify commissioning and troubleshooting, while the DIN rail mounting system allows convenient integration alongside other modular electrical components.

Typical Applications

• Residential and commercial electrical distribution boards.
• Remote switching of lighting circuits and electrical loads.
• Building automation and facility management systems.
• Complementary switching using normally open and normally closed contacts.
• Electrical heating control within specified load ratings.
• Ventilation and building services equipment.
• Industrial electrical control panels and automation systems.
• Control circuits requiring two simultaneous contact-state changes.
• Electrical installation and panel-building projects.
• General-purpose electrical switching with 230 V AC control circuits.
