Why Choose the Finder 65.31.9.110.4000 Power Relay?
The Finder 65.31.9.110.4000 is a heavy-duty 20 A industrial electromechanical power relay designed for dependable electrical switching in machinery, industrial automation and electrical control panels. Part of the established Finder 65 Series, this model combines a 110 V DC operating coil with one normally open and one normally closed contact (1 NO + 1 NC).
Featuring silver tin oxide (AgSnO₂) contacts, the Finder 65.31.9.110.4000 is designed for repeated switching of compatible industrial electrical loads. Its 20 A rated contact current, 250 V AC rated contact voltage and 5,000 VA AC1 resistive switching capacity make it suitable for industrial heating, machinery control, electrical load switching and automation equipment.
The relay provides two independently wired switching contacts, allowing one circuit to close while another opens when the coil is energised. Its Faston 250 quick-connect terminals and rear flange mounting arrangement support convenient installation in compatible industrial panels and equipment.

Reliable 20 A Switching for 110 V DC Industrial Control Systems
The Finder 65.31.9.110.4000 operates as an electrically controlled switching device. When its 110 V DC coil is energised, the normally open contact closes and the normally closed contact opens. When the coil supply is removed, both contacts return to their original positions.
This 1 NO + 1 NC contact arrangement is particularly useful where one circuit must be activated while another is disconnected. Applications include auxiliary equipment control, electrical signalling, industrial machinery and complementary switching functions. Unlike a conventional changeover contact, the relay's normally open and normally closed contacts are independently wired and do not share a common terminal.
The silver tin oxide contact material supports repeated switching within the manufacturer's specified electrical limits. Its 20 A rated contact current and 5,000 VA AC1 resistive switching capacity make it suitable for appropriately rated industrial power circuits. Actual permissible switching current depends on load type, voltage, switching frequency and environmental conditions.
With Faston 250 quick-connect terminals and a rear flange mounting arrangement, the Finder 65.31.9.110.4000 offers a practical installation solution for compatible electrical panels and equipment. Its 110 V DC coil makes it particularly relevant to industrial control systems and equipment designed around this nominal DC supply voltage.
