Reliable Power Switching for Industrial Automation and Electrical Equipment
Electromechanical power relays such as the Finder 66.82.8.110.4301 allow an AC control circuit to operate separate electrical loads through an electromagnetic switching mechanism. When the 110 V AC coil is energised, the relay closes its two normally open contacts, allowing current to flow through the connected load circuits. When the coil is de-energised, the contacts return to their normally open positions, disconnecting the controlled circuits.
The Finder Series 66 is developed for electrical switching applications requiring robust contacts, dependable operation and practical installation. The 66.82.8.110.4301 combines flange mounting with Faston terminals and wash-tight construction, making it suitable for integration into industrial equipment and commercial electrical assemblies. Correct conductor sizing, compatible connectors, protective devices and load assessment are essential when switching higher-current circuits.
Typical Applications
- Industrial automation and electrical control systems.
- Industrial machinery and equipment switching circuits.
- Heating, ventilation and air conditioning (HVAC) equipment.
- Commercial and industrial washing machines.
- Electrical heating and temperature control equipment.
- Industrial ovens and appliance control systems.
- Auxiliary motor and electrical load switching circuits.
- Power management and electrical distribution control equipment.
- OEM machinery requiring flange-mounted power relays.

Frequently Asked Questions
What is the Finder 66.82.8.110.4301 used for?
The Finder 66.82.8.110.4301 is an electromechanical power relay used for switching electrical loads in industrial automation, machinery control, HVAC equipment and commercial electrical systems.
What coil voltage does the Finder 66.82.8.110.4301 require?
The relay requires a 110 V AC nominal coil supply. It is designed for use with a suitable AC control circuit rather than a DC coil supply.
What contact configuration does this Finder relay have?
The Finder 66.82.8.110.4301 features two normally open contacts (2 NO / DPST-NO), allowing two electrical circuits to be switched simultaneously when the relay coil is energised.
What is the switching current rating of the Finder 66.82.8.110.4301?
The relay has a 30 A contact rating. The permissible switching load depends on the operating voltage, load characteristics and applicable manufacturer specifications.
How is the Finder 66.82.8.110.4301 installed?
The relay uses a flange mounting arrangement for secure mechanical installation and Faston 250 quick-connect terminals for electrical connections.
What does wash-tight construction mean for this relay?
The wash-tight construction provides additional protection against ingress during appropriate equipment manufacturing and cleaning processes. It does not mean the relay is suitable for unrestricted water exposure or outdoor installation without a suitable enclosure.
What contact material is used in the Finder 66.82.8.110.4301?
The relay uses silver tin oxide (AgSnO2) contacts, which offer good resistance to electrical wear and contact welding in demanding switching applications.
Can the Finder 66.82.8.110.4301 replace a DPDT changeover relay?
Not as a direct functional replacement. The 66.82.8.110.4301 has two normally open contacts, whereas a DPDT changeover relay provides normally open and normally closed switching paths. The contact arrangement and wiring requirements must be checked before selecting a replacement.
