1sna295428r2500 – circuit separator

Why Choose the TE Connectivity 1SNA295428R2500 SCHD1 Circuit Separator?

The TE Connectivity 1SNA295428R2500, also identified as SCHD1, is a beige 1.2 mm circuit separator designed for compatible Entrelec screw-clamp terminal block assemblies. It provides physical and insulating separation between adjacent terminal circuits, helping panel builders organise terminal strips and maintain clear separation between functional groups.

Designed for the Entrelec HD terminal system, the SCHD1 is particularly suited to compatible HD4/9.F4 stud terminal blocks. Its slim 1.2 mm width adds circuit separation with minimal impact on DIN-rail space, while the polyamide construction provides durable insulation for industrial electrical installations.

The separator measures 22.5 mm high and 54 mm deep, weighs approximately 2 g and is specified for operation from -55 to +110 °C. Compatibility with TH35 and Type 2 mounting-rail arrangements makes it a practical accessory for industrial control, machinery and transportation terminal assemblies.

Reliable Circuit Separation for Industrial Terminal Assemblies

Circuit separators are used within modular terminal strips to create additional physical and visual separation between neighbouring circuits or functional groups. The SCHD1 provides this separation in a slim 1.2 mm profile, allowing panel builders to improve circuit organisation without unnecessarily increasing the overall width of the terminal assembly.

Its polyamide construction, broad operating temperature range and matched compatibility with HD-series terminal blocks make the SCHD1 suitable for demanding industrial applications. When incorporated into the intended terminal assembly, it supports an organised installation while providing an insulating barrier between adjacent terminal positions.

Typical Applications

• Separation of circuits within HD4/9.F4 terminal assemblies.
• Industrial electrical control panels.
• Stud and screw-clamp terminal strips.
• Machine-building electrical systems.
• Transportation and railway electrical equipment.
• DIN-rail power and control distribution assemblies.
