Finder 22.72.0.024.1410 – 22 Series Modular contactors

Why Choose the Finder 22.72.0.024.1410 Modular Contactor?

The Finder 22.72.0.024.1410 is a compact 32 A, two-pole modular contactor designed for dependable electrical load switching in residential, commercial and industrial installations. Part of the Finder Series 22, this contactor combines a space-saving DIN rail design with reliable electromechanical operation for distribution boards, lighting control and building automation systems.

Featuring a 24 V AC/DC silent operating coil and 2 normally closed (2 NC) contacts, the Finder 22.72.0.024.1410 provides a practical switching solution for applications where the contacts must remain closed when the coil is de-energised. Applying the appropriate control voltage opens both contacts, enabling controlled disconnection of compatible electrical circuits.

Its 32 A rated contact current, silver nickel (AgNi) contacts and compact 17.5 mm-wide housing make it suitable for space-conscious electrical installations. The contactor also incorporates a silent AC/DC coil with varistor protection, reinforced insulation between coil and contacts, and a mechanical operating indicator for convenient inspection.

Key Advantages

• 32 A rated switching current for compatible electrical loads.
• 2 normally closed contacts provide a closed circuit in the de-energised state.
• 24 V AC/DC operating coil supports compatible AC and DC control systems.

Reliable Normally Closed Switching for Electrical Automation

The Finder 22.72.0.024.1410 operates differently from a normally open modular contactor. Its two normally closed contacts remain closed while the operating coil is de-energised. When the 24 V AC/DC coil receives its control supply, both contacts open, allowing a control system to interrupt the connected circuits.

This arrangement is useful where electrical equipment must operate in the normal, unenergised state and be disconnected when a control signal is applied. The contactor's monostable construction ensures that its contacts return to their normally closed positions when the coil supply is removed.

The silent AC/DC coil makes the contactor particularly suitable for building services installations where operating noise should be kept low. Its integrated varistor helps manage coil switching transients, while the mechanical indicator allows installers to inspect the operating condition without relying solely on external control signals.

With its compact 17.5 mm width and standard DIN rail mounting arrangement, the Finder 22.72.0.024.1410 can be integrated into electrical distribution boards and automation cabinets alongside circuit breakers, timers and control relays. Connected loads must be selected according to the applicable utilisation category, switching current and manufacturer specifications.
