Finder 077.03.8.230 – 77 Series Modular solid state relays- Accessory

Why Choose the Finder 077.03.8.230 Heat Sink with Cooling Fan?

The Finder 077.03.8.230 is a fan-cooled heat sink for Finder Series 77 solid state relays (SSRs), designed to provide effective thermal management in industrial electrical control and automation applications. Featuring an integrated 230 V AC cooling fan rated at 14.5 W, this accessory helps dissipate heat generated during solid state relay operation.

Designed for compatible single-phase, two-phase and three-phase Finder SSRs, the 077.03.8.230 combines a heat-dissipating structure with forced-air cooling. This makes it a practical solution for installations where solid state relays generate significant heat during continuous or frequent electrical load switching.

As part of Finder's Series 77 thermal management accessory range, the 077.03.8.230 supports compatible hockey puck-style solid state relays and Finder thermal interface pads. Its manufacturer-specified compatibility helps electrical panel builders, automation engineers and maintenance professionals select an appropriate cooling arrangement for industrial control systems.

Effective Forced-Air Cooling for Solid State Relays

Solid state relays use semiconductor switching devices that generate heat while conducting electrical current. Effective heat dissipation is therefore essential to maintaining suitable operating temperatures and avoiding excessive thermal stress. The Finder 077.03.8.230 provides a dedicated heat sink combined with a 230 V AC, 14.5 W cooling fan, helping transfer heat away from the installed relay and into the surrounding air.

Finder specifies the 077.03.8.230 for selected Series 77 single-, two- and three-phase SSRs, with compatible 077.T1, 077.T2 and 077.T3 thermal pads used to support heat transfer at the mounting interface. The required thermal arrangement must be assessed using the relay's load current, power dissipation, ambient temperature, enclosure ventilation and relevant Finder thermal guidance. The cooling accessory does not increase the relay's published electrical ratings or replace the need for suitable circuit protection.

Typical Applications

• Finder Series 77 solid state relay installations.
• Industrial electric heating control systems.
• Temperature-controlled machinery and process equipment.
• Single-phase SSR thermal management.
• Two-phase and three-phase SSR switching assemblies.
• Industrial automation and electrical control cabinets.
• Power switching systems requiring forced-air cooling.
• Control panels with continuous or frequently operated SSR loads.
• Maintenance and replacement of Finder SSR cooling accessories.
