66.82.8.230.4301 Finder Power relay 2pole 30A 230V

Why Choose the Finder 66.82.8.230.4301 Power Relay?

The Finder 66.82.8.230.4301 is a heavy-duty 30 A industrial electromagnetic power relay designed for reliable switching of electrical loads in industrial machinery, heating equipment and automation systems. Part of the established Finder 66 Series, this relay combines a 230 V AC operating coil, two normally open contacts (DPST-NO) and a wash-tight RT III enclosure.

The 66.82.8.230.4301 features top flange mounting and Faston 250 quick-connect terminals, allowing secure mechanical installation and convenient electrical connections in control panels and industrial equipment. Its silver tin oxide (AgSnO2) contacts are designed for dependable high-current switching under suitable electrical load conditions.

With a 230 V AC, 50/60 Hz coil, 30 A rated contact current and 250 V AC rated contact voltage, the Finder 66.82.8.230.4301 is suitable for demanding industrial power control applications. Reinforced insulation between the coil and contacts provides additional electrical separation, while the RT III construction distinguishes this wash-tight variant from the standard RT II version.

Wash-Tight High-Current Switching for Industrial Equipment

The Finder 66.82.8.230.4301 uses an electromagnetic coil to control two normally open power contacts. When the 230 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 66.82.8.230.4300. The wash-tight version is designed to provide additional protection against suitable manufacturing washing processes. However, RT III classification does not mean the relay is intended for permanent immersion, pressure washing or unrestricted outdoor exposure.

The 66.82 flange-mounted configuration is particularly useful where a relay must be attached directly to an equipment frame or control panel rather than soldered onto a printed circuit board. Its Faston 250 terminals provide detachable electrical connections, while the reinforced insulation and high-current contacts support reliable industrial power switching.

The relay's 30 A contact rating applies to specified switching conditions. Resistive, inductive and motor loads can place different demands on the contacts, so the appropriate electrical rating, inrush current and switching frequency should be considered when selecting the relay.

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 equipment.
• Motor control and auxiliary power switching circuits.
• OEM electrical assemblies requiring wash-tight relay construction.
• Flange-mounted electrical switching equipment using Faston connections.
