Why Choose the Finder 65.31.8.230.4300 Power Relay?
The Finder 65.31.8.230.4300 is a robust electromechanical power relay designed for switching high-current loads in industrial machinery, automation equipment and electrical control systems. Part of the proven Finder 65 Series, it combines a 230 V AC coil with a single normally open contact rated at 30 A.
This relay uses cadmium-free silver tin oxide contacts to provide reliable switching performance under demanding operating conditions. Its normally open contact has a separation of at least 3 mm when de-energised, supporting effective circuit isolation in equipment designed around the requirements of EN 60335-1.
The 65.31.8.230.4300 features a rear mounting flange and Faston 250 quick-connect terminals measuring 6.3 × 0.8 mm. Its 7,500 VA AC1 load capacity makes it suitable for controlling motors, pumps, heaters, compressors and other substantial electrical loads within industrial control panels.

Reliable Power Switching for Industrial Equipment
Electromechanical power relays allow a control circuit to operate a separate, higher-current electrical load. Applying 230 V AC to the coil energises the Finder 65.31.8.230.4300 and closes its normally open contact, allowing connected machinery or equipment to operate.
The Finder 65 Series is designed for applications where high switching capacity, effective circuit isolation and secure panel installation are required. The relay’s 30 A contact, high instantaneous current capability and rear mounting flange make it particularly suitable for demanding industrial control duties.
Typical Applications
- Industrial machinery and automation systems.
- Pump, compressor and motor control panels.
- Heating, ventilation and refrigeration equipment.
- Power distribution and electrical control cabinets.
- Industrial washing and processing machinery.
- Generators and uninterruptible power supply equipment.
