66.82.9.024.4601 Finder Power relay 2pole 30A DC 24V

Why Choose the Finder 66.82.9.024.4601 Power Relay?

The Finder 66.82.9.024.4601 is a heavy-duty 30 A industrial electromagnetic power relay designed for reliable high-current switching in industrial machinery, automation systems and electrical control equipment. Part of the Finder 66 Series, this model combines a 24 V DC operating coil, two normally open contacts (DPST-NO) and an increased contact gap of at least 1.5 mm.

The 66.82.9.024.4601 features RT III wash-tight construction, offering additional environmental protection during suitable manufacturing washing processes. It also incorporates top flange mounting and Faston 250 quick-connect terminals, making it practical for installation in electrical enclosures and machinery without direct PCB soldering.

Its combination of a 24 V DC control coil, high-current contacts, increased open-contact separation and reinforced coil-to-contact insulation makes this relay particularly useful in demanding electrical switching applications. The 1.5 mm minimum contact gap is especially relevant to equipment designs requiring enhanced separation between open contacts, including suitable photovoltaic inverter applications.

Key Advantages

• 30 A rated contact current for demanding industrial electrical loads.
• 24 V DC operating coil for compatible low-voltage DC control systems.

Wash-Tight Power Switching with Increased Contact Separation

The Finder 66.82.9.024.4601 uses a 24 V DC electromagnetic coil to control two normally open power contacts. When the coil is energised, both contacts close, allowing current to flow through the connected circuits. When the coil supply is removed, the contacts return to their normally open positions.

The 4601 configuration combines two important characteristics: a minimum 1.5 mm open-contact gap and RT III wash-tight construction. The increased contact gap provides greater physical separation between open contacts, while the wash-tight enclosure offers additional protection during suitable manufacturing washing processes. RT III classification does not mean that the relay is intended for permanent immersion, pressure washing or unrestricted outdoor exposure.

The increased-gap design is relevant to applications such as photovoltaic inverter switching, where specific contact separation requirements may apply. However, the relay must be assessed as part of the complete equipment design; its contact gap alone does not establish compliance with every isolation, disconnection or photovoltaic safety requirement.

The 66.82 flange-mounted housing and Faston 250 connections make this relay suitable for machinery and electrical assemblies requiring secure mechanical installation and detachable wiring. As with any power relay, the connected load type, inrush current, switching frequency and operating temperature must be considered when confirming suitability.
