77 Series SSRs: Efficient performance and advanced thermal management for Industry 4.0.

Finder expands the 77 Series Solid State Relay range with new dedicated accessories for maximum efficiency.

Designed for intensive industrial use, Finder 77 Series SSRs (commonly known as "hockey puck" style) eliminate the typical issues associated with electromechanical contacts, ensuring a virtually unlimited electrical life and the total absence of electric arcs or contact bounce. This makes them the ideal choice for the precise and reliable management of a wide range of loads:

- Resistive loads: Perfect for heaters and industrial ovens.
- Motor and solenoid loads: Optimized control for starting and stopping.
- Lighting systems: Effective management of high inrush currents.

Finder 77 Series: dedicated accessories for maximum efficiency The key to maintaining the high performance of Solid State Relays, especially under harsh environmental conditions, lies in effective thermal management. Finder addresses this need by introducing a complete line of specific thermal accessories—a dedicated dissipation ecosystem designed to prevent overheating and ensure consistent performance according to specifications.

1. Heat sinks: allies for long-term durability The use of an adequate heat sink is vital for the longevity of every SSR. These new heat sinks can be installed on 35 mm rail (EN 60715) or directly onto the panel backplate. For more demanding applications, versions with integrated fans are available to drastically increase heat dissipation capacity:

- Type 077.03.9.024: 24 V DC supply.
- Type 077.03.8.230: 230 V AC supply.

2. Thermal Pads: the indispensable thermal bridge To maximize heat transfer from the relay to the heat sink or the metallic wall of the cabinet, the new thermal pads are a crucial component:

- 077.T1 / 077.T2: Specific for single-phase and two-phase models (the T2 version is adhesive-backed for easier positioning).
- 077.T3: Sized specifically for the larger surface area of three-phase SSRs.

Strategic advantages for panel builders Choosing the 77 Series and integrating it with original Finder thermal components provides tangible benefits for industrial installations:

- High reliability: Advanced thermal management protects the investment and ensures intensive duty cycles without failure.
- Energy efficiency: The low-consumption input circuit reduces auxiliary power requirements.
- Compactness and space optimization: The integrated system allows for the best use of space within the electrical enclosure, keeping it ready for the challenges of Industry 4.0.
