66.82.9.024.0003 Finder Power relay 2pole 30A DC 24V

Why Choose the Finder 66.82.9.024.0003 ATEX Industrial Power Relay?

The Finder 66.82.9.024.0003 is a heavy-duty 30 A industrial power relay from the Finder 66 Series, featuring a 24 V DC operating coil, two changeover contacts and a flange-mounted housing with Faston 250 quick-connect terminals. Designed for demanding electrical switching applications, this model offers reliable electromechanical operation for industrial automation, machinery control and power management equipment.

Unlike two-pole normally open relays, the Finder 66.82.9.024.0003 incorporates two changeover contacts (2 CO / DPDT), allowing each pole to switch between normally closed and normally open circuits. The contact system is rated at 30 A for normally open contacts and 10 A for normally closed contacts under the applicable standard ratings. This arrangement provides flexibility for electrical control, switching and interlocking applications.

The .0003 variant is identified as a Class I Division 2 / ATEX power relay, intended for applications requiring appropriately certified electrical components. It features silver cadmium oxide (AgCdO) contacts, top flange mounting and 6.3 mm Faston 250 connections. Its reinforced insulation between the coil and contacts further supports integration into professional industrial electrical equipment.

Key Advantages

• 30 A normally open contact rating supports demanding electrical switching applications.
• 10 A normally closed contact rating provides additional control and switching flexibility.
• Two changeover contacts (DPDT) enable simultaneous switching between normally open and normally closed circuits.
• 24 V DC coil integrates with commonly used industrial DC control supplies.
• ATEX / Class I Division 2 variant supports appropriately designed installations requiring hazardous-location-rated components.
• Top flange mounting provides secure mechanical installation in suitable equipment assemblies.
• Faston 250 quick-connect terminals simplify electrical connections and servicing.
• AgCdO contact material supports robust electromechanical switching.
• Reinforced coil-to-contact insulation helps maintain separation between control and load circuits.
• Monostable operation automatically returns contacts to their normal positions when coil power is removed.

Reliable High-Current Switching for Industrial and Hazardous-Location Applications

The Finder 66.82.9.024.0003 operates through an electromagnetic mechanism controlled by a 24 V DC coil. When the coil is energised, both changeover contacts transfer from their normally closed positions to their normally open positions. Removing the coil supply releases the mechanism and returns the contacts to their normal states. This makes the relay suitable for applications requiring coordinated switching, auxiliary control or electrical interlocking.

The Finder 66.82 Series combines high-current contacts, flange mounting and Faston connections for installation in industrial electrical assemblies. The .0003 hazardous-location variant offers additional application possibilities where the relevant equipment certification is required. Its use in potentially explosive atmospheres must comply with the precise ATEX or hazardous-location marking, temperature classification, electrical limits and installation requirements applicable to the equipment. Contact ratings must also be assessed against the actual load, especially for motors, inductive circuits and high-inrush equipment.

Typical Applications

• Industrial automation and machinery control equipment.
• Electrical switching in appropriately designed hazardous-location assemblies.
• Industrial heating and temperature control systems.
• Motor control and auxiliary switching circuits.
• Power distribution and electrical control panels.
• Industrial process control and monitoring equipment.
• Electrical interlocking and changeover switching applications.
• OEM machinery and specialised industrial electrical equipment.
