Finder 22.23.8.048.4000 – 22 Series Modular monostable relays

Why Choose the Finder 22.23.8.048.4000 Modular Installation Relay?

The Finder 22.23.8.048.4000 is a reliable and compact 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 installation relay range, it provides dependable electromechanical switching with a versatile combination of normally open and normally closed contacts.

Featuring a 48 V AC operating coil and a 1 normally open (NO) + 1 normally closed (NC) contact configuration, the relay enables control circuits to operate electrical loads while providing complementary switching functions. Its monostable mechanism ensures that the contacts automatically return to their normal positions when the coil is de-energised, making it suitable for lighting control, electrical distribution and building automation applications.

With a 20 A rated switching current, a 250 V AC rated contact voltage and a maximum switching voltage of 400 V AC, the Finder 22.23.8.048.4000 provides flexible switching performance in a compact modular housing. Its approximately 17.4 mm width and standard 35 mm DIN rail mounting make it particularly suitable for electrical distribution boards and control panels where installation space is limited.

Reliable Electrical Switching for Building and Industrial Automation

Modular installation relays such as the Finder 22.23.8.048.4000 provide a practical method of controlling electrical loads through a separate operating circuit. When the 48 V AC coil is energised, the normally open contact closes while the normally closed contact opens. When the coil supply is removed, the monostable mechanism automatically restores both contacts to their original positions.

This complementary contact arrangement allows the relay to perform two switching functions from a single control signal. It is particularly useful for electrical installations requiring simultaneous switching of separate circuits, status-dependent load control or coordinated operation of connected electrical equipment.

The Finder Series 22 combines compact DIN rail construction with reliable electromechanical switching technology. Its 20 A contact rating and silver tin oxide contact material make it suitable for a variety of lighting and general electrical load-control applications, provided the connected equipment remains within the manufacturer's specified electrical ratings.

Designed for installation in electrical distribution boards and control cabinets, the relay offers straightforward integration alongside circuit breakers, timers and other modular automation components. Its compact housing helps installers build organised, space-efficient electrical control systems.

Typical Applications

• Residential electrical distribution boards and control panels.
• Commercial building lighting control systems.
• Industrial electrical switching and automation cabinets.
