Reliable High-Current Switching with Enhanced Contact Separation
The Finder 65.61.9.012.0300S allows a 12 V DC control circuit to operate a separate, higher-power electrical load. When the relay coil is energised, its normally open contact closes and completes the load circuit. Removing the coil supply causes the contact to open, interrupting power to the connected equipment.
A key feature of the 65.61-0300 configuration is its minimum 3 mm contact gap. This provides increased physical separation between the open contacts, making the relay suitable for equipment designs where enhanced contact separation is required. Any use for safety-related disconnection must still be assessed against the relevant equipment standards and circuit design.
The combination of a 30 A switching rating, AgCdO contact material and PCB mounting makes this relay a practical choice for industrial electronic assemblies. Its 12 V DC coil can be operated by a suitably rated control circuit, allowing electronic controllers to switch heating elements, machinery functions and other compatible electrical loads. Appropriate coil suppression, load protection and PCB conductor sizing should be considered during installation.

Frequently Asked Questions
What is the Finder 65.61.9.012.0300S used for?
The Finder 65.61.9.012.0300S is a 30 A electromagnetic power relay used to switch suitable electrical loads in industrial automation, heating systems, machinery and electronic control assemblies. It operates using a 12 V DC coil and a single normally open contact.
What coil voltage does the Finder 65.61.9.012.0300S require?
The relay requires a 12 V DC nominal coil supply. Its DC coil is non-polarised and monostable, meaning the contact returns to its normal open position when the coil is de-energised.
What is the contact rating of the Finder 65.61.9.012.0300S?
The relay has a 30 A rated contact current for suitable resistive loads at 250 V AC, with a rated resistive switching capacity of 7500 VA (AC1). Its maximum AC switching voltage is 400 V AC. The permissible switching current must be checked against the actual load type and voltage.
What is the benefit of the 3 mm contact gap?
The minimum 3 mm contact gap provides enhanced physical separation between the relay contacts when open. This can be beneficial in equipment requiring increased contact separation, although compliance with any specific disconnection or safety standard depends on the complete equipment design.
