Spring Cage Terminal

FST2.5-QUATTRO

This 4P (4-pole) DIN Rail Cable Terminal Block with innovative spring cage technology provides a compact yet powerful connection solution for industrial control systems and power distribution applications. Featuring a 5.2mm pitch, it enables high-density wiring while maintaining excellent electrical isolation between poles.

Engineered to meet IEC/EN 61984-7-1 standards, this terminal block guarantees reliable performance in demanding environments. The PA66 housing material offers superior flame resistance (UL94 rated) and mechanical durability, while the tin-plated copper alloy terminals ensure optimal conductivity and corrosion resistance.

Designed for efficient installations, it accommodates 24-12AWG wires (up to 2.5mm²) with its maintenance-free spring cage connection system, eliminating the need for screw tightening while providing vibration-resistant contacts. Rated for 24A current and 800V voltage per IEC standards, it delivers robust power handling capacity in compact control panels and switchgear.
