Why Choose the Finder 66.82.8.024.4300 Power Relay?
The Finder 66.82.8.024.4300 is a heavy-duty 30 A industrial electromagnetic power relay designed for reliable switching of electrical loads in industrial machinery, automation equipment and electrical control systems. Part of the established Finder 66 Series, this relay features a 24 V AC operating coil and a double-pole normally open (DPST-NO) contact configuration, enabling simultaneous control of two independent electrical circuits.
Unlike PCB-mounted variants in the Finder 66 Series, the 66.82.8.024.4300 features top flange mounting with Faston 250 quick-connect terminals. This arrangement supports secure mechanical installation and convenient wiring in electrical control panels, industrial equipment and OEM assemblies. Its silver tin oxide (AgSnO2) contacts are designed for dependable switching performance under suitable electrical load conditions.
With a 24 V AC, 50/60 Hz coil, 30 A rated contact current and 250 V AC rated contact voltage, the Finder 66.82.8.024.4300 provides a practical switching solution for heating equipment, machinery controllers and industrial power circuits. Reinforced insulation between the coil and contacts further supports reliable electrical separation in demanding installations.

Reliable High-Current Switching with Flange Mounting
The Finder 66.82.8.024.4300 allows two electrical load circuits to be controlled using a separate low-voltage AC coil circuit. When the 24 V AC coil is energised, the relay's electromagnetic mechanism closes both normally open contacts, allowing current to flow through the connected circuits. When the coil is de-energised, the contacts return to their normally open positions.
The 66.82 mounting configuration is particularly useful where a relay must be fixed directly to a panel or equipment structure rather than soldered onto a printed circuit board. Its top flange allows mechanical fixing, while the Faston 250 terminals provide detachable electrical connections. This arrangement can simplify installation, replacement and maintenance in industrial electrical assemblies.
The combination of 30 A contact capability, AgSnO2 contact material and reinforced insulation makes this relay suitable for a range of industrial switching duties. However, the permissible load must always be assessed against the applicable resistive, inductive or motor switching ratings, particularly where frequent switching or substantial inrush currents are involved.
Typical Applications
- Industrial automation and electrical control panels.
- Power switching circuits in manufacturing machinery.
- Industrial heating equipment, ovens and furnaces.

- Air conditioning, ventilation and HVAC equipment.
- Commercial laundry and industrial washing equipment.
- Electrical generators and standby power equipment.
- Motor control and auxiliary switching circuits.
- Panel-mounted electrical power switching assemblies.
- OEM machinery and industrial electronic control systems.
