Finder 022.74 – 22 Series Modular contactors – Accessory

Why Choose the Finder 022.74 Series 32A 4-Pole Modular Contactor?

The Finder 022.74, commonly identified as the Finder Type 22.74, belongs to Finder's Series 22 range of modular installation contactors. Designed for reliable electrical load switching, this 32 A, 4-pole modular contactor family provides electrically controlled switching for lighting, building services, industrial control panels and electrical distribution applications.

The Finder 22.74 range combines a compact DIN rail-mounted design with a quiet AC/DC operating coil, integrated varistor protection and mechanically operated contact indication. Available contact arrangements include 4 normally open (4 NO), 3 normally open plus 1 normally closed (3 NO + 1 NC), 2 NO + 2 NC and 4 NC, depending on the complete manufacturer part number.

Designed for installation on a standard 35 mm DIN rail, the Finder 22.74 modular contactor family offers dependable switching performance for appropriately rated electrical loads. Its silver-nickel (AgNi) contacts, double-break contact construction and continuous-duty design make it suitable for professional electrical installations requiring reliable remotely controlled switching.

Reliable Four-Pole Electrical Load Switching

The Finder Type 22.74 operates through an electromagnetic coil that changes the state of its switching contacts when the appropriate control voltage is applied. This allows electrical loads to be switched remotely by timers, control relays, building automation equipment or other suitable control devices. The four-pole design supports different circuit arrangements, while the availability of normally open and normally closed contact configurations allows installers to select the appropriate variant for the intended switching function.

Selected Finder 22.74 mirror-contact variants provide a normally closed contact designed to indicate the state of associated normally open contacts in accordance with the relevant mirror-contact requirements. These variants can support suitable control and monitoring applications when incorporated into a properly designed system. The contactor itself is not an overload or short-circuit protective device; appropriate circuit protection must be provided separately. The exact coil voltage, contact arrangement and accessory compatibility must be confirmed using the complete Finder ordering code.

Typical Applications

• Commercial and industrial lighting control systems.
• Building automation and electrical load management.
• DIN rail-mounted electrical distribution boards.
• Heating, ventilation and building services switching.
• Industrial automation and control panels.
• Remote switching of appropriately rated electrical loads.
• Electrical equipment control using timers and relays.
• Electric vehicle charging control assemblies using suitable variants.
• Contactor monitoring and safety-related control circuits using specified mirror-contact versions.
