Overview

The Degson D10B-SEH-4g-M25 is a DIN rail terminal block engineered for secure 4mm² wire connections with a 25A current rating. Its housing is constructed from PA66 material, achieving UL94V-0 flame resistance for safety in high-temperature environments. Internal components include a stainless steel spring and a tin-plated copper alloy clamp, ensuring corrosion resistance and reliable conductivity. The terminal block meets UL standards with a 150V/4A rating and accommodates both rigid and flexible wires ranging from 20-6 AWG (0.5-10mm²). With a compact 10.16mm pitch, it supports multi-pole configurations in dense industrial panels. Ideal for automation systems, power distribution, and control panels where stable, high-current connections are critical. The stainless steel spring provides consistent clamping force, reducing the risk of loose connections or arcing. The tin-plated copper clamp enhances durability and prevents oxidation, extending service life in harsh conditions. Designed for quick installation on standard DIN rails, it simplifies wiring in space-constrained enclosures. Compliance with UL standards ensures compatibility with North American electrical systems.
