55.33.9.024.2000 Finder Miniature plugin relay 3 pole 10A DC 24V

Q: What is the Finder 55.33.9.024.2000 used for?

The Finder 55.33.9.024.2000 is a plug-in industrial relay used for switching electrical circuits in automation equipment, industrial machinery and control panels. Its three changeover contacts allow three independent circuits to be controlled using one relay coil.

Q: What coil voltage does the Finder 55.33.9.024.2000 require?

The relay operates from a nominal 24 V DC supply. It has a nominal coil resistance of 600 Ω, a nominal coil current of 40 mA and a specified coil operating voltage range of 19.2–26.4 V DC.

Q: What is the switching capacity of the Finder 55.33.9.024.2000?

The relay has a 10 A rated contact current at 250 V AC, a maximum switching voltage of 400 V AC and a rated resistive AC1 switching load of 2,500 VA. The permissible switching load depends on the connected equipment and operating conditions.

Q: What does the 3PDT contact configuration mean?

3PDT means three-pole double-throw, also described as 3 CO or three changeover contacts. Each pole provides a common, normally open and normally closed connection, enabling three separate circuits to change state together when the relay coil is energised.

Q: How is the Finder 55.33.9.024.2000 installed?

The relay uses plug-in socket mounting and is designed for compatible Finder Series 94 three-pole relay sockets. Suitable sockets allow installation in electrical control panels, including DIN rail-mounted assemblies. The socket is selected separately to suit the installation.

Why Choose the Finder 55.33.9.024.2000 Industrial Relay?

The Finder 55.33.9.024.2000 is a compact 10 A plug-in electromechanical relay designed for industrial automation, electrical control panels and general-purpose switching applications. Part of the Finder Series 55 miniature relay range, it combines three changeover contacts with a convenient socket-mounted design for flexible electrical control.

Featuring a three-pole double-throw (3PDT, 3 CO) contact arrangement, the relay enables three independent electrical circuits to be switched simultaneously using one electromagnetic coil. Its 24 V DC nominal coil voltage is suitable for compatible low-voltage control systems, while its 10 A rated contacts support industrial switching applications within the specified load limits.

The Finder 55.33.9.024.2000 uses a plug-in connection system compatible with suitable Finder Series 94 relay sockets. This allows convenient installation, removal and replacement during maintenance. Its compact construction and versatile contact arrangement make it suitable for industrial machinery, PLC interface circuits, control cabinets and OEM electrical equipment.

Flexible Three-Pole Switching for Industrial Control Systems

Electromechanical relays such as the Finder Series 55 use an electromagnetic coil to operate mechanically linked switching contacts. When the coil is energised, all three changeover contacts transfer from their normally closed positions to their normally open positions. When the coil supply is removed, the contacts return to their original positions. This allows one control signal to operate three separate circuits while maintaining galvanic isolation between the coil and contact systems.

The Finder 55.33.9.024.2000 is particularly useful in control systems requiring multiple switching functions from a single relay. Its 3PDT configuration can be used for auxiliary control, signalling, electrical interlocking and equipment switching, while the 24 V DC coil supports operation from an appropriately rated industrial DC power supply.

The plug-in construction allows the relay to be installed into a compatible socket, simplifying servicing and replacement. Finder Series 94 sockets offer installation options for control panels, including 35 mm DIN rail mounting. Engineers should select the appropriate socket and consider the electrical characteristics of the connected loads, switching frequency, coil suppression requirements and contact protection when designing an installation.

Typical Applications

Industrial automation and process control systems.
Electrical control panels and relay interface assemblies.
PLC-controlled auxiliary switching circuits.
Industrial machinery and OEM electrical equipment.
Building automation and building management systems.
Electrical interlocking and multi-circuit control.
Control circuit switching and status signalling.
Maintenance-friendly plug-in relay installations.
