Why Choose the Finder 66.82.9.012.4600 Power Relay?
The Finder 66.82.9.012.4600 is a heavy-duty 30 A industrial electromagnetic power relay designed for dependable high-current switching in industrial machinery, electrical control panels and automation equipment. Part of the established Finder 66 Series, this model features a 12 V DC operating coil, two normally open contacts (DPST-NO) and an increased contact gap for applications requiring enhanced separation between open contacts.
The 66.82.9.012.4600 uses top flange mounting and Faston 250 quick-connect terminals, providing a practical alternative to PCB-mounted relays. Its flange-mounted construction allows secure mechanical fixing, while the detachable terminal connections simplify wiring, equipment assembly and maintenance.
A distinguishing feature of the 4600 configuration is its normally open contact arrangement with a contact gap of at least 1.5 mm. Combined with a 12 V DC coil, reinforced coil-to-contact insulation and high-current switching capability, this relay is well suited to industrial equipment requiring reliable power control and increased open-contact separation.

High-Current Switching with Increased Contact Separation
The Finder 66.82.9.012.4600 uses a 12 V DC electromagnetic coil to control two normally open contact circuits. When the coil is energised, the relay mechanism closes both contacts, allowing current to flow through the connected electrical loads. When the coil supply is removed, the contacts return to their normally open positions.
The 4600 contact configuration is particularly important when comparing this model with standard Finder 66 Series normally open relays. Its minimum 1.5 mm open-contact gap provides increased physical separation between the contacts when the relay is de-energised. This feature can be useful in equipment designs requiring enhanced contact separation, although the complete installation must still satisfy any applicable isolation and safety requirements.
The 66.82 flange-mounted construction makes the relay suitable for electrical equipment where direct mechanical fixing is preferred over PCB mounting. Its Faston 250 terminals provide detachable connections, helping simplify installation and maintenance in machinery, industrial control panels and OEM assemblies.
When selecting this relay, the 30 A rated contact current should be assessed alongside the electrical characteristics of the connected load. Resistive loads, motors and inductive circuits can have different switching requirements, and the applicable manufacturer ratings must be observed.
Typical Applications
- Industrial automation and electrical control systems.
- Manufacturing machinery and equipment controllers.
- Industrial heating equipment and temperature control systems.
- Boiler and burner control equipment.
- Air conditioning, ventilation and HVAC systems.
- Industrial washing and commercial laundry equipment.
- Electrical generators and auxiliary power control systems.
- Motor control and electrical switching assemblies.
- OEM equipment requiring increased open-contact separation.
- Flange-mounted power switching circuits using Faston terminals.
