Why Choose the Finder 66.82.9.024.4000 Power Relay?
The Finder 66.82.9.024.4000 is a high-current 30 A electromechanical power relay designed for dependable electrical switching in industrial automation, machinery and commercial control equipment. Part of the established Finder Series 66, this relay combines a low-voltage DC operating coil, robust changeover contacts and convenient flange-mounted installation.
Featuring a 24 V DC coil and two changeover contacts (2 CO / DPDT), the Finder 66.82.9.024.4000 enables two independent electrical circuits to be controlled simultaneously. Its top flange mounting arrangement and Faston 250 quick-connect terminals make it suitable for integration into industrial electrical panels, machinery and OEM equipment.
With a 30 A normally open contact rating, 10 A normally closed contact rating and silver tin oxide (AgSnO2) contact material, this relay supports demanding power switching applications. Reinforced insulation between the coil and contacts helps maintain electrical separation between the low-voltage control circuit and connected loads.

Reliable High-Current Switching with 24 V DC Control
The Finder 66.82.9.024.4000 operates through a DC electromagnetic coil that controls two changeover contact sets. When the rated 24 V DC control voltage is applied, the relay transfers its contacts from their normally closed positions to their normally open positions. This enables two independent electrical circuits to be switched while maintaining electrical separation between the control supply and connected loads.
The Finder Series 66 is engineered for demanding industrial and commercial switching applications. The 66.82.9.024.4000 combines high-current silver tin oxide contacts, reinforced insulation and durable electromagnetic construction to support reliable operation in machinery, heating equipment and power management systems. Its flange-mounted design and Faston terminals provide practical advantages during installation, maintenance and replacement.
The relay's 24 V DC coil makes it particularly suitable for control panels using low-voltage DC supplies, including PLC-controlled equipment. Actual load compatibility should always be assessed against the manufacturer's ratings for the applicable AC or DC utilisation category.
Typical Applications
- Industrial automation and electrical control systems.
- 24 V DC control panels and PLC interfaces.
- Heating, ventilation and air conditioning equipment.
- Industrial washing machines and commercial appliances.
- Boiler, burner and industrial oven control circuits.
- Power generators and standby power equipment.
- Motor control and auxiliary switching circuits.
- Industrial machinery and production equipment.
- Electrical control panels and power switching assemblies.
- OEM equipment requiring flange-mounted high-current power relays.
