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.
