66.82.9.024.1003 Finder Power relay 2pole 30A DC 24V

Why Choose the Finder 66.82.9.024.1003 Power Relay?

The Finder 66.82.9.024.1003 is a high-current electromechanical power relay from the Finder Series 66 range, designed for industrial electrical switching, automation equipment and machinery control applications. Combining a 24 V DC operating coil, double-pole changeover contacts and flange-mounted construction, it provides an effective means of controlling electrical loads through a separate DC control circuit.

This model features double-pole double-throw (DPDT / 2 CO) contacts, allowing two independent circuits to change state simultaneously. Its silver nickel (AgNi) contact material provides a cadmium-free contact option, while the electromagnetic operating mechanism offers reliable, non-latching switching. The relay's reinforced insulation between coil and contacts supports electrical separation between the control circuit and connected loads.

The Finder 66.82.9.024.1003 combines a 30 A normally open contact rating, 250 V AC rated contact voltage and Faston 250 quick-connect terminals for demanding electrical installations. Its Series 66 design is suitable for industrial heating, HVAC systems, machinery and power switching equipment where secure mounting and dependable contact operation are important.

Dependable 24 V DC Control of High-Current Electrical Loads

The Finder 66.82.9.024.1003 enables a 24 V DC control circuit to operate higher-current electrical loads through mechanically isolated switching contacts. When the relay coil is energised, its electromagnetic mechanism transfers both changeover contacts from their normally closed positions to their normally open positions. When the coil is de-energised, the contacts return to their normal states.

The Finder Series 66.82 combines high-current switching capability with reinforced insulation, flange mounting and Faston 250 electrical connections. Its silver nickel contacts provide a cadmium-free material option within the relay family. For reliable operation, the connected load must remain within the applicable contact ratings, and the coil driver should be appropriately rated and protected against switching transients.

Typical Applications

• Industrial automation systems using 24 V DC control circuits.
• PLC-controlled electrical switching assemblies.
• Industrial machinery and manufacturing equipment.
• Heating, ventilation and air conditioning (HVAC) controls.
• Industrial heating and temperature control equipment.
• High-current resistive load switching.
• Electrical control panels and power management systems.
• Commercial appliances and industrial processing machinery.
• Motor auxiliary circuits within applicable contact ratings.
• OEM equipment requiring double-pole changeover switching.
