Finder 022.35 – 22 Series Modular contactors – Accessory

Why Choose the Finder 022.35 Auxiliary Contact Module?

The Finder 022.35 is a compact and reliable 1 normally open (NO) + 1 normally closed (NC) auxiliary contact module designed to extend the switching, signalling and control capabilities of compatible Finder Series 22 modular contactors. Featuring a 6 A conventional thermal current rating, this auxiliary contact block provides additional control circuits for commercial electrical installations, building automation and industrial control systems.

As part of the Finder Series 22 modular contactor accessory range, the 022.35 is designed for side mounting onto compatible Finder 22.32 and 22.34 modular contactors. Its mechanically linked auxiliary contacts operate together with the main contactor, allowing electrical engineers to implement contactor status indication, interlocking, feedback signalling and automatic control functions without installing a separate auxiliary relay.

With a 1 NO + 1 NC contact configuration, a 6 A thermal current rating and an AC-15 switching rating of 700 VA at 230 V AC, the Finder 022.35 provides flexible auxiliary switching for low-voltage control circuits. Its slim side-mounted construction, silver-nickel contact material and secure screw terminals make it an effective solution for electrical distribution boards, DIN rail control assemblies and automation panels.

Reliable Auxiliary Switching for Electrical Control and Automation

Auxiliary contact modules such as the Finder 022.35 provide additional electrical switching contacts that operate mechanically with a compatible modular contactor. When the associated contactor is energised and changes state, the normally open auxiliary contact closes while the normally closed auxiliary contact opens. This complementary switching arrangement enables control circuits to respond automatically to the operating condition of the contactor.

The 1 NO + 1 NC configuration is particularly useful for contactor status monitoring, electrical interlocking and control circuit feedback. For example, the normally open contact can provide a signal indicating that the contactor has operated, while the normally closed contact can be used for an alternative control or indication function. Both contacts operate in conjunction with the contactor mechanism, helping simplify wiring and reduce the need for additional switching components.

The Finder 022.35 uses silver-nickel contact material and a compact side-mounted construction to provide reliable auxiliary switching in commercial and industrial electrical installations. Its compatibility with the Finder Series 22 modular contactor platform supports efficient panel assembly and straightforward integration into existing control systems. The accessory must be fitted to a compatible contactor and is not suitable for the Finder 22.32.0.xxx.x4x0 two normally closed contactor versions.
