55.33.9.220.2000 Finder Miniature plugin relay 3 pole 10A DC 220V

Why Choose the Finder 55.33.9.220.2000 Miniature Industrial Relay?

The Finder 55.33.9.220.2000 is a compact miniature industrial electromagnetic relay from the established Finder 55 Series, designed for reliable electrical switching in automation, machinery control and electronic equipment. Featuring a 220 V DC nominal coil and three changeover contacts (3 CO / 3PDT), this relay provides a practical solution for controlling multiple electrical circuits through a single control signal.

The Finder 55.33 relay configuration combines three independently wired changeover contact sets with a compact construction suitable for printed circuit board integration. Each contact provides common, normally open and normally closed connections, allowing engineers to perform multiple switching functions using one electromagnetic relay.

With a 10 A nominal contact current rating associated with the Finder 55.33 configuration, the 55.33.9.220.2000 is suitable for appropriately rated electrical switching applications. Its 220 V DC coil makes it relevant to control systems employing higher-voltage DC supplies, while the relay's monostable operation ensures that its contacts return to their normal positions when the coil is de-energised.

Key Advantages

• 220 V DC nominal coil: Suitable for compatible high-voltage DC control circuits.
• Three changeover contacts: Enables coordinated switching of three separate electrical circuits.

Reliable Three-Pole Switching for Industrial Control Systems

The Finder 55.33.9.220.2000 uses an electromagnetic coil to operate three mechanically linked changeover contact sets. When the appropriate 220 V DC control voltage is applied, the relay changes the position of its contacts. When the coil supply is removed, the contacts return to their normal positions, providing conventional monostable switching behaviour.

The 3PDT contact arrangement allows a single control signal to operate three separate switching circuits. Each pole provides a common connection that switches between normally closed and normally open terminals, supporting applications involving electrical control logic, signal routing, equipment status indication and coordinated switching.

The relay's 10 A nominal contact rating supports a range of industrial switching requirements. However, the permissible switching load depends on the operating voltage, load characteristics, power factor, inrush current and switching frequency. Engineers should ensure that the selected relay, PCB layout and protective components are suitable for the intended electrical application.

Because this model uses a 220 V DC coil, particular attention should be given to the control supply and coil-switching arrangement. Suitable suppression may be required when switching the inductive coil, and any suppression component should be selected with consideration for the coil voltage, operating characteristics and required relay release time.

Typical Applications

• Industrial automation and machine control systems.
• Printed circuit board control assemblies.
• Electrical control panels and electronic equipment.
• Industrial machinery and OEM control systems.
• Higher-voltage DC control circuits.
• Control signal switching and electrical interfacing.
• Electrical signalling and equipment status indication.
• Three-pole switching applications requiring a 220 V DC-operated relay.
