Why Choose the Finder 65.31.9.012.0300 Power Relay?
The Finder 65.31.9.012.0300 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 12 V DC coil with a single normally open contact rated at 30 A.
This relay uses silver cadmium oxide contacts to provide reliable switching 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 65.31.9.012.0300 features a rear mounting flange and Faston 250 quick-connect terminals measuring 6.3 × 0.8 mm. Its low-voltage DC coil and 7,500 VA AC1 load capacity make it suitable for controllers and automation systems that must switch motors, pumps, heaters and other substantial electrical loads.

Reliable Power Switching for Industrial Equipment
Electromechanical power relays allow a low-voltage control circuit to operate a separate, higher-current electrical load. Applying 12 V DC to the coil energises the Finder 65.31.9.012.0300 and closes its normally open contact, allowing connected machinery or equipment to operate.
The Finder 65 Series is designed for industrial applications where high switching capacity, effective circuit isolation and secure panel installation are required. The low-voltage coil, 30 A contact and rear mounting flange make this relay suitable for integration with electronic controllers and automation equipment.
Typical Applications
- Industrial machinery and automation systems.
- PLC and electronic control circuits.
- Pump, compressor and motor control panels.
- Heating, ventilation and refrigeration equipment.
- Power distribution and electrical control cabinets.
