Why Choose the Finder 65.31.8.230.4000 Power Relay?
The Finder 65.31.8.230.4000 is a heavy-duty electromechanical power relay designed for dependable switching in industrial machinery, automation equipment and electrical control systems. Part of the proven Finder 65 Series, it combines a 230 V AC coil with one normally open and one normally closed contact rated at 20 A.
This relay uses cadmium-free silver tin oxide contacts, providing reliable switching performance for demanding electrical loads. Its changeover-style contact arrangement allows one circuit to close while the other opens when the coil is energised, supporting flexible control, interlocking and change-of-state applications.
The 65.31.8.230.4000 features a rear mounting flange and Faston 250 quick-connect terminals measuring 6.3 × 0.8 mm. This construction enables straightforward installation and secure wiring in control panels, distribution assemblies, heating equipment, pumps, motors and industrial machinery.
Key Advantages
- Heavy-duty electromechanical relay for industrial power switching.
- One normally open and one normally closed contact for flexible control.
- 20 A nominal contact rating for demanding electrical loads.
- 230 V AC coil suitable for mains-powered control circuits.
- Cadmium-free silver tin oxide contacts provide dependable switching performance.
- Rear mounting flange and Faston terminals simplify panel installation.
Key Features
- Finder 65 Series power relay.
- 1 NO + 1 NC contact configuration.
- 20 A nominal contact current.
- 230 V AC rated coil voltage.
- 5,000 VA maximum AC1 switching capacity.
- Silver tin oxide (AgSnO2) contact material.
- Faston 250 terminals measuring 6.3 × 0.8 mm.
- Monostable, non-polarised operating mechanism.
Reliable Power Switching for Industrial Equipment
Electromechanical power relays allow a control circuit to operate a separate, higher-current electrical load. When 230 V AC is applied to the coil, the normally open contact closes and the normally closed contact opens, providing two complementary switching states from a single control signal.
The Finder 65 Series is designed for robust industrial applications where dependable switching, electrical isolation and convenient installation are essential. The high-current contacts and mechanical mounting flange make this relay suitable for incorporation into machinery and electrical control assemblies.
Typical Applications
- Industrial machinery and automation systems.
- Pump and motor control panels.
- Heating, ventilation and refrigeration equipment.
- Power distribution and control cabinets.
- Industrial washing and processing machinery.
- Generators and uninterruptible power supply equipment.
