55.33.9.024.2010 Finder Miniature plugin relay 3 pole 10A DC 24V

Why Choose the Finder 55.33.9.024.2010 General Purpose Relay?

The Finder 55.33.9.024.2010 is a 24 V DC general purpose electromechanical relay from the Finder 55 Series, designed for electrical switching, industrial automation and equipment control applications. Its three changeover contacts (3 CO / 3PDT) allow multiple switching functions to be controlled from a single relay coil.

The 24 V DC coil makes this relay relevant to industrial control systems using low-voltage DC supplies. The Finder 55.33 family is associated with a 10 A rated contact current, offering useful switching capability for appropriately specified loads. Its changeover contact arrangement provides normally open and normally closed switching options for signalling, auxiliary control and interlocking applications.

The Finder 55.33.9.024.2010 is part of a versatile relay range used in industrial electrical assemblies and OEM equipment. The complete ordering code is important when selecting a replacement because contact material, coil characteristics, terminal layout and optional construction features can vary between Finder 55 Series models.

Three-Pole Changeover Switching for 24 V DC Control Systems

The Finder 55.33.9.024.2010 provides a practical way to control multiple electrical circuits using a single 24 V DC control signal. Its three changeover contacts can be assigned to separate switching, signalling or auxiliary functions, allowing several operations to take place simultaneously when the relay coil is energised.

Each changeover contact provides a common connection, a normally closed connection and a normally open connection. When the coil is energised, the contacts transfer to their operated positions. When the coil supply is removed, the relay returns to its normal state. This behaviour is useful in conventional control logic, equipment status circuits and electrical interlocking arrangements.

The 10 A rated contact current offers useful switching capacity, but it must not be interpreted as a universal limit for every load. Resistive, inductive, motor and high-inrush loads can have different permissible switching currents. Engineers should check the relevant manufacturer load ratings before selecting the relay for a particular circuit.

When integrating the relay into a 24 V DC control system, the control output must be capable of supplying the required coil current. The complete relay variant should also be checked for any polarity-sensitive components or suppression arrangements before the coil is connected. Suitable protection may be required when driving the relay from an electronic controller.

The Finder 55.33 family is relevant to industrial control equipment where compact electromechanical switching and multiple contact functions are required. It can be used in appropriately designed automation systems, electrical assemblies and machinery control circuits, provided the electrical ratings and installation conditions are observed.

For maintenance or replacement, the complete 55.33.9.024.2010 part number should be matched rather than relying solely on the 24 V DC coil voltage and three-pole contact arrangement. Similar relays may differ in contact material, mounting method, terminal layout and other construction details.

• Multi-circuit auxiliary switching.
• Equipment status and alarm signalling.
• Electrical interlocking functions.
• Industrial process control equipment.
• Building services control systems.
• Electronic and electromechanical control assemblies.
• Replacement of compatible Finder 55.33 relays.
