Why Choose the Finder 66.82.8.024.4301 Power Relay?
The Finder 66.82.8.024.4301 is a heavy-duty 30 A industrial electromagnetic power relay designed for reliable electrical load switching in industrial machinery, heating equipment and automation systems. Part of the Finder 66 Series, this model combines a 24 V AC operating coil, two normally open contacts (DPST-NO) and a wash-tight RT III enclosure.
Unlike standard RT II variants, the 66.82.8.024.4301 features a wash-tight construction intended to provide additional protection during suitable equipment manufacturing and cleaning processes. The relay also incorporates top flange mounting and Faston 250 quick-connect terminals, allowing secure mechanical installation and convenient electrical connections without direct PCB soldering.
Its silver tin oxide (AgSnO2) contacts support durable electrical switching, while the 30 A rated contact current and 250 V AC rated contact voltage make it suitable for demanding power control duties. Reinforced insulation between the coil and contacts, together with an 8 mm creepage and clearance distance, supports reliable electrical separation in industrial applications.

Wash-Tight High-Current Switching for Industrial Equipment
The Finder 66.82.8.024.4301 uses an electromagnetic coil to control two normally open power contacts. When the 24 V AC coil is energised, both contacts close, allowing current to flow through the connected load circuits. When the coil is de-energised, the contacts return to their normally open positions.
The RT III wash-tight construction is an important distinction between this model and the standard 66.82.8.024.4300. The wash-tight version is intended to provide additional protection against the effects of suitable manufacturing wash processes. This classification does not mean the relay is designed for permanent immersion or unrestricted outdoor exposure; installation conditions must remain within the manufacturer's specifications.
The 66.82 flange-mounted design is particularly useful where direct mounting to an equipment frame or control panel is preferred over PCB installation. Its Faston terminals provide detachable electrical connections, while reinforced insulation and high-current contacts support integration into industrial power switching equipment.
Typical Applications
- Industrial automation and electrical control panels.
- Manufacturing machinery and equipment controllers.
- Industrial heating equipment, ovens and furnaces.
- Boiler and burner control systems.
- Air conditioning, ventilation and HVAC equipment.
- Industrial washing and commercial laundry machinery.
- Electrical generators and standby power systems.
- Motor control and auxiliary power switching circuits.
- OEM electrical assemblies requiring wash-tight relay construction.
- Flange-mounted power switching equipment using Faston connections.
