65.61.9.024.4300 Finder Power relay PCB 1NO1 NC 20A DC 24V

Why Choose the Finder 65.61.9.024.4300 Power Relay?

The Finder 65.61.9.024.4300 is a high-performance 30 A electromagnetic power relay designed for reliable switching of electrical loads in industrial automation, machinery control and commercial equipment. Featuring a 24 V DC operating coil and a single normally open (SPST-NO) contact, this relay allows a low-voltage industrial control circuit to operate higher-power electrical equipment.

Part of the established Finder 65 Series power relay range, the 65.61.9.024.4300 combines a high-current contact system with silver tin oxide (AgSnO₂) contact material and direct printed circuit board (PCB) mounting. Its minimum 3 mm contact gap provides enhanced physical separation between the open contacts, making it particularly useful in electrical equipment requiring increased contact isolation.

With a 30 A rated contact current at 250 V AC, 7500 VA resistive switching capacity (AC1) and a 24 V DC coil, the Finder 65.61.9.024.4300 is well suited to industrial heating systems, automated machinery, electrical control assemblies and OEM equipment. Its PCB-mounted design provides a practical solution for integrating high-current electromagnetic switching into industrial electronic control boards.

Reliable High-Current Switching with 24 V DC Control

The Finder 65.61.9.024.4300 enables a 24 V DC control circuit to switch a separate higher-power electrical load. When the coil is energised, its normally open contact closes and completes the load circuit. Removing the coil voltage causes the relay to return to its normal state, opening the contact and interrupting current flow to the connected equipment.

The relay's 30 A contact rating and silver tin oxide contact material make it suitable for demanding electrical switching applications. Its minimum 3 mm contact gap provides increased physical separation between the contacts when open, supporting equipment designs that require enhanced contact isolation. Any safety-related disconnection function must be assessed against the applicable equipment standards and overall circuit design.

The 24 V DC coil is particularly useful in industrial automation systems using standard DC control supplies. Combined with direct PCB mounting, this makes the Finder 65.61.9.024.4300 a practical choice for electronic control boards, heating equipment and machinery. Suitable coil suppression, protective devices, PCB copper dimensions and electrical clearances should be incorporated into the final installation.
