Why Choose the Finder 65.31.8.230.4009 Power Relay?

The Finder 65.31.8.230.4009 is a heavy-duty 20 A industrial power relay with a 230 V AC coil, designed for dependable electrical switching in machinery, industrial automation and electrical control panels. Part of the established Finder 65 Series, this electromechanical relay combines high-current switching capability with a versatile normally open and normally closed contact arrangement.

Featuring one normally open (NO) and one normally closed (NC) contact, the relay enables two complementary switching functions from a single control signal. When its 230 V AC coil is energised, the normally open contact closes while the normally closed contact opens. This arrangement is particularly useful for equipment control, electrical interlocking, auxiliary switching and industrial machinery applications.

The Finder 65.31.8.230.4009 offers a 20 A resistive contact rating at 250 V AC, durable silver tin oxide (AgSnO2) contacts and a panel-mounting arrangement with 6.3 × 0.8 mm quick-connect terminals. Its robust construction makes it a practical choice for machine builders, automation engineers and maintenance professionals requiring reliable switching in demanding electrical environments.

Reliable Electrical Switching for Industrial Automation

The Finder 65.31.8.230.4009 provides dependable electrical switching using a separate 230 V AC control signal. When the relay coil is energised, its electromagnetic mechanism closes the normally open contact and opens the normally closed contact. When the coil is de-energised, both contacts return to their normal positions, allowing complementary control functions to be performed from a single relay.

Its 20 A rated resistive contacts make this relay suitable for higher-current industrial applications where conventional lower-rated control relays may not be appropriate. The silver tin oxide contact material supports durable electromechanical switching, while the normally open and normally closed contact arrangement enables equipment status changes, control interlocking and alternative circuit operation.

The relay's panel-mounting construction and 6.3 × 0.8 mm quick-connect terminals support practical integration into machinery and electrical control cabinets. For reliable service, the connected load must remain within the applicable contact ratings. Inductive loads, motors, capacitive loads and DC circuits may require additional derating or contact protection. The normally open and normally closed contacts are separate switching paths rather than a single changeover contact.

Typical Applications

  • Industrial automation and machinery control panels.
  • 230 V AC control and signalling systems.
  • Higher-current electrical load switching.
  • Industrial machinery and automated production equipment.
  • Auxiliary contactor and motor control circuits.
  • Electrical interlocking and complementary switching functions.
  • Heating, ventilation and air conditioning equipment.
  • Industrial process control and monitoring systems.
  • Electrical distribution and control cabinet assemblies.
  • Building management and facility automation systems.
  • OEM machinery and industrial electrical equipment manufacturing.
