Why Choose the Finder 22.74.0.024.1410 Modular Contactor?
The Finder 22.74.0.024.1410 is a professional 32 A four-pole modular installation contactor designed for reliable electrical switching in distribution boards, building automation systems and industrial control panels. Part of the Finder 22 Series, this contactor features four normally closed contacts (4NC) and a 24 V AC/DC operating coil.
Its 4NC contact configuration is particularly useful for applications requiring circuits to remain connected while the control coil is de-energised. When the 24 V AC/DC coil is energised, all four normally closed contacts open simultaneously, allowing a single control signal to interrupt multiple appropriately rated circuits.
The Finder 22.74.0.024.1410 combines silver-nickel (AgNi) contacts, a silent AC/DC coil, integrated varistor protection and mechanical contact-position indication. With a compact 35 mm DIN rail housing, it provides a practical solution for electrical contractors, panel builders and automation engineers requiring dependable four-pole normally closed switching.

How the Finder 22.74 Four-Pole Normally Closed Contactor Works
The Finder 22.74.0.024.1410 differs from conventional normally open installation contactors because all four of its main contacts are normally closed. In the unenergised condition, these contacts provide electrical continuity between their respective terminals, subject to the connected circuits and installation design.
When the contactor receives a suitable 24 V AC/DC control signal, its electromagnetic coil operates and opens all four contacts. This interrupts the connected circuits simultaneously. Removing the control voltage allows the contacts to return to their normally closed positions.
This operating principle makes the contactor suitable for applications where a control signal must disconnect several circuits together. It may be incorporated into suitably designed electrical control, load-management and automation arrangements. However, a normally closed contactor is not inherently a safety-rated isolation device, and the required behaviour during loss of control power must be considered carefully.
The contactor has a 32 A AC-1 operating current rating, making it suitable for appropriately rated non-inductive or slightly inductive loads. For motor applications, the specified AC-3 operating current is 8.5 A at 400 V AC, with a corresponding three-phase motor power rating of 4 kW. Motor starting conditions, overload protection and the complete circuit design must be checked before installation.
Its AgNi contacts are intended for the manufacturer's specified electrical switching duties. Where the contactor is being considered for LED lighting or other electronic loads, installers should verify the applicable load ratings and inrush-current characteristics rather than relying solely on the general 32 A rating.
The silent AC/DC coil allows operation from compatible alternating-current and direct-current control supplies. Integrated varistor protection helps suppress switching transients, while the mechanical indicator provides visual confirmation of the contactor's operating position.
With a 35 mm housing width, the Finder 22.74.0.024.1410 fits into standard modular distribution equipment while occupying approximately two DIN rail modules. Its screw terminals and 35 mm DIN rail mounting support convenient installation in professional control panels.

Frequently Asked Questions
What is the Finder 22.74.0.024.1410 used for?
The Finder 22.74.0.024.1410 is a 32 A four-pole modular contactor used to control compatible electrical loads through a 24 V AC/DC coil. Its four normally closed contacts make it suitable for applications requiring multiple circuits to open when a control signal is applied.
What contact configuration does the Finder 22.74.0.024.1410 have?
The contactor has four normally closed contacts (4NC) and no normally open main contacts. All four contacts open when the coil is energised and close again when the coil is de-energised.
What coil voltage does the Finder 22.74.0.024.1410 require?
The contactor has a 24 V AC/DC nominal coil. It can be controlled using a compatible 24 V AC supply at 50/60 Hz or a suitable 24 V DC supply, within the manufacturer's specified operating limits.
What is the rated current of the Finder 22.74.0.024.1410?
The contactor has a 32 A rated operating current under AC-1 conditions. The allowable current for other loads depends on the relevant utilisation category and the electrical characteristics of the connected equipment.
What happens when the Finder 22.74.0.024.1410 coil is energised?
When the 24 V AC/DC coil is energised, all four normally closed contacts open, interrupting their connected circuits. When the control supply is removed, the contacts return to their normally closed positions.
Is the Finder 22.74.0.024.1410 a latching contactor?
No. It is a non-latching electromagnetic contactor. Its four normally closed contacts remain open while the coil is energised and return to their closed state when the control voltage is removed.
Can the Finder 22.74.0.024.1410 be used for motor control?
Yes, for appropriately rated motor circuits. The contactor has an AC-3 operating current rating of 8.5 A at 400 V AC and a corresponding 4 kW three-phase motor rating. Suitable overload protection and motor starting requirements must be considered.
Can this contactor switch LED lighting?
It may be used with compatible LED lighting loads, but the 32 A AC-1 rating is not an LED-specific switching rating. The connected LED drivers' inrush currents and the manufacturer's applicable load limits must be checked before installation.
Does the Finder 22.74.0.024.1410 have a silent coil?
Yes. The contactor uses a silent AC/DC coil designed to minimise audible operating noise. It also includes integrated varistor protection to help suppress coil switching transients.
What contact material is used?
The Finder 22.74.0.024.1410 uses silver-nickel (AgNi) contacts, suitable for the manufacturer's specified resistive and inductive switching applications.
Does the contactor have an operating-status indicator?
Yes. The contactor includes a mechanical contact-position indicator, allowing installers to check its operating state visually during commissioning and maintenance.
Where is the Finder 22.74.0.024.1410 installed?
The contactor is designed for 35 mm DIN rail mounting inside a suitable electrical distribution board or control enclosure. Its 35 mm housing width occupies approximately two standard DIN rail modules.
What happens if the control power supply fails?
Because this is a normally closed, non-latching contactor, loss of coil power causes the contacts to return to their closed positions. This behaviour must be considered carefully when designing electrical control or safety-related systems.
What is the difference between Finder 22.74.0.024.1410 and 22.74.0.024.1310?
The 22.74.0.024.1410 has four normally closed contacts (4NC), while the 22.74.0.024.1310 has four normally open contacts (4NO). Both are 32 A four-pole contactors with 24 V AC/DC coils, but their opposite contact arrangements mean they are not direct substitutes.
