Why Choose the Finder 66.82.9.024.4301 Power Relay?
The Finder 66.82.9.024.4301 is a high-current 30 A electromechanical power relay from the Finder 66 Series, featuring a 24 V DC coil, two normally open contacts and a wash-tight construction for industrial electrical switching applications. Designed for integration into control panels, machinery and OEM equipment, this relay combines robust electromagnetic operation with practical flange mounting and Faston quick-connect terminals.
The relay features a two-pole normally open (2 NO / DPST-NO) contact configuration, allowing two independent electrical circuits to be switched simultaneously through a single control signal. Its silver tin oxide (AgSnO₂) contacts provide high-current switching capability, while the non-latching electromagnetic mechanism returns the contacts to their open positions when the coil is de-energised.
A distinguishing feature of the 66.82.9.024.4301 is its RT III wash-tight protection category, providing a sealed relay construction suited to appropriate equipment manufacturing and assembly processes. Combined with reinforced coil-to-contact insulation, a 250 V AC rated contact voltage and 7500 VA AC1 resistive switching capacity, it offers a versatile solution for demanding industrial control applications.

Reliable Power Switching for Industrial Automation
Electromechanical power relays enable low-voltage control circuits to operate higher-current electrical loads through mechanically actuated contacts. When the 24 V DC coil of the Finder 66.82.9.024.4301 is energised, its electromagnetic mechanism closes both normally open contacts, allowing current to flow through the connected load circuits. When the coil is de-energised, the contacts return to their normally open positions.
The Finder 66.82.9.024.4301 is particularly suitable for applications where a 24 V DC control signal must operate two electrical circuits simultaneously. Its RT III wash-tight construction distinguishes it from standard RT II versions and can be advantageous in suitable equipment assembly processes. The flange-mounted design and Faston terminals facilitate integration into industrial machinery, heating systems and OEM electrical assemblies.
For dependable operation, electrical engineers should assess the load category, operating voltage, starting current and switching frequency against the relay's published ratings. The RT III classification describes the relay's wash-tight construction and should not be interpreted as an unrestricted waterproof or outdoor enclosure rating.
