55.33.9.220.5000 Finder Miniature plugin relay 3 pole 10A DC 220V
Finder 55.33.9.220.5000 is a Series 55 miniature industrial electromechanical relay featuring a 220 V DC coil and three changeover contacts in a 3PDT configuration for multi-circuit electrical control applications.
Why Choose the Finder 55.33.9.220.5000 Miniature Industrial Relay?
The Finder 55.33.9.220.5000 is a miniature electromechanical relay from the Finder Series 55 range, designed for industrial automation, electrical control panels and auxiliary switching applications. Its three-pole changeover configuration allows multiple electrical circuits to be operated using a single control signal.
Featuring a 220 V DC nominal coil and three changeover contacts (3 CO / 3PDT), this relay provides flexible normally open and normally closed switching options for compatible industrial control systems. Its electromagnetic operating mechanism enables the control circuit to actuate electrically separate contact circuits.
The Finder 55.33 relay family is suitable for installations requiring compact, replaceable industrial switching components. The complete 55.33.9.220.5000 designation identifies the specific coil voltage and manufacturer variant, making accurate part-number matching important when selecting replacements.
Key Advantages
- 220 V DC nominal coil for compatible direct-current control circuits.
- Three changeover contacts enable simultaneous switching of multiple circuits.
- 3PDT contact configuration provides normally open and normally closed switching paths.
- Compact industrial relay construction supports organised control panel layouts.
- Electromagnetic switching provides separation between coil and contact circuits.
- Monostable operation returns the contacts to their normal positions when the coil is de-energised.
- Suitable for relay-based control logic, signalling and auxiliary switching.
- Part of the established Finder Series 55 miniature industrial relay family.
- Complete 5000 variant designation supports accurate component identification.
Key Features
- Finder Series 55 miniature industrial relay.
- Type 55.33 three-pole construction.
- 220 V DC nominal coil voltage.
- Three changeover contacts (3 CO / 3PDT).
- Three independent contact circuits operated by a common coil.
- Electromagnetic, monostable switching mechanism.
- Plug-in relay construction.
- Suitable for compatible industrial relay sockets.
- Designed for industrial control and auxiliary switching applications.
- 5000 manufacturer configuration.
Three-Pole Changeover Switching for DC Control Systems
The Finder 55.33.9.220.5000 uses an electromagnetic coil to operate three changeover contacts simultaneously. When the appropriate 220 V DC coil supply is applied, each common contact transfers from its normally closed connection to its normally open connection. Removing the coil supply allows the contacts to return to their normal positions.
This switching arrangement allows a single control signal to operate three electrically separate circuits, making the relay useful for industrial control logic, auxiliary equipment switching and signalling applications. Its plug-in construction also supports servicing and replacement when installed with a compatible relay socket.
The connected loads, control supply and terminal connections must be checked against the complete manufacturer specification before installation. In particular, the 220 V DC coil must not be confused with a 220 V AC coil or with the voltage rating of the switching contacts.
Typical Applications
- Industrial automation and electrical control panels.
- 220 V DC auxiliary control circuits.
- Machinery control and auxiliary switching.
- Multi-circuit relay logic applications.
- Electrical signalling and monitoring circuits.
- Industrial equipment interfacing.
- OEM machinery and electrical control assemblies.
- Maintenance and replacement of compatible Finder Series 55 relays.

Frequently Asked Questions
What is the Finder 55.33.9.220.5000 used for?
It is a miniature industrial electromagnetic relay used to switch multiple electrical circuits in automation equipment, control panels and auxiliary switching systems.
What coil voltage does the Finder 55.33.9.220.5000 require?
The relay has a 220 V DC nominal coil and requires a compatible direct-current control supply.
How many changeover contacts does this relay have?
The Finder 55.33.9.220.5000 provides three changeover contacts (3 CO / 3PDT), each with common, normally open and normally closed connections.
What does 3PDT mean?
3PDT means three-pole double-throw. The relay can switch three separate common contacts between normally closed and normally open circuit paths.
Is the Finder 55.33.9.220.5000 an AC coil relay?
No. The 9.220 designation identifies a 220 V DC coil. It should not be connected to an AC control supply unless specifically permitted by the manufacturer's instructions.
Is the Finder 55.33.9.220.5000 a latching relay?
No. It is a monostable electromagnetic relay, meaning its contacts return to their normal positions when the coil supply is removed.
Can this relay be used with a plug-in socket?
Yes. Finder Type 55.33 relays use a plug-in construction intended for compatible relay sockets. The socket configuration and terminal connections must be checked before installation.
Can a different Finder Series 55 relay replace this model?
Replacement suitability depends on the coil voltage, contact arrangement, switching ratings, socket compatibility and manufacturer variant. The complete 55.33.9.220.5000 part number should be matched before substitution.
What does the 5000 suffix identify?
The 5000 suffix forms part of the manufacturer's relay configuration. It should be retained when identifying or ordering this specific model because variants within the same relay family may differ.
