The Finder 66.82.8.230.4000 is a heavy-duty 30 A electromagnetic power relay designed for reliable high-current switching in industrial automation, electrical control and power management applications. Featuring a 230 V AC operating coil and two changeover contacts (2 CO / DPDT), this relay provides versatile control of two independent electrical circuits.
As part of the established Finder Series 66 power relay range, the 66.82.8.230.4000 combines substantial switching capacity with durable silver tin oxide (AgSnO₂) contacts and a practical flange-mounted design with Faston 250 connections. Its double-pole changeover configuration provides both normally open and normally closed switching paths, making it suitable for industrial machinery, power equipment and automated control systems.
With a 30 A nominal normally open contact rating, 10 A normally closed contact rating and 250 V AC nominal switching voltage, the Finder 66.82.8.230.4000 offers dependable power switching performance. Its reinforced coil-to-contact insulation, wide operating temperature range and accessible quick-connect terminals make it a practical choice for industrial equipment manufacturers and electrical control engineers.
Electromagnetic power relays such as the Finder 66.82.8.230.4000 provide electrical load control through a separate coil-operated switching mechanism. When the 230 V AC coil is energised, the relay transfers its two changeover contacts from their normally closed positions to their normally open positions. When the coil is de-energised, the contacts return to their original state.
The Finder Series 66 is designed for applications requiring high contact current capacity, dependable switching and electrical insulation between control and load circuits. The 66.82.8.230.4000 uses AgSnO₂ contacts to help resist electrical wear, while its two-pole changeover configuration supports load switching, circuit selection and control interlocking applications.
Unlike PCB-mounted versions within the Series 66 range, the 66.82.8.230.4000 features flange mounting and Faston 250 terminals, allowing direct installation onto suitable equipment panels and connection using compatible quick-connect terminals. Its 30 A normally open contact rating and wide operating temperature range make it suitable for demanding electrical switching duties, provided that conductor sizing, terminal protection, load-specific derating and thermal management are correctly considered.

The Finder 66.82.8.230.4000 is a high-current electromagnetic power relay used for switching electrical loads in industrial machinery, heating equipment, HVAC systems, power generators and automation applications. Its two changeover contacts provide flexible control of two independent circuits.
The relay features a 230 V AC nominal operating coil designed for 50/60 Hz supplies. Its specified operating voltage range is 184–253 V AC.
The Finder 66.82.8.230.4000 has a 30 A nominal normally open contact rating and a 10 A nominal normally closed contact rating. The maximum permissible switching current depends on the electrical load, operating voltage and utilisation category.
DPDT (Double Pole Double Throw) means the relay contains two independent changeover contact sets. Each set can transfer a circuit between normally closed and normally open connections when the relay coil is energised.
The relay features a flange-mounted design for installation onto suitable panels or equipment mounting surfaces. Electrical connections are made using Faston 250 quick-connect terminals measuring 6.3 × 0.8 mm.
The Finder 66.82 relay type uses flange mounting with Faston 250 connections, while the Finder 66.22 relay type is designed for PCB mounting. Both belong to the Series 66 power relay family, but their mounting and electrical connection arrangements differ.
Yes. The relay can switch appropriately rated DC loads. For normally open contacts, the DC-1 resistive breaking capacities include 25 A at 24 V DC, 0.7 A at 110 V DC and 0.3 A at 220 V DC. DC switching capacity depends on voltage and load characteristics.
