ST2.5 QUATTRO Spring Din Rail Terminal Block

If you need to connect and route four 2.5mm² wires in a tight panel space, the CHTAR ST2.5 QUATTRO Spring DIN Rail Terminal Block is designed to solve that. It features a true two-in, two-out (2-in/2-out) configuration, allowing all four conductors to be active simultaneously. This makes it ideal for splitting or combining circuits where space is at a premium. The connection is secured by its reliable cage-clamp spring mechanism, which ensures a firm, vibration-resistant grip on every wire, providing a compact and dependable branching solution.

Product Description

Evaluating a terminal block often means looking beyond unit cost. The ST2.5 QUATTRO Spring Din Rail Terminal Block is engineered for total cost of ownership. Its electrical specs—800V, 28A, 6kV surge—mean it can be applied in harsh Category III/PD3 environments without being the weak link, preventing costly field failures. The high 130°C RTI similarly guards against thermal aging.

This intrinsic robustness is externally validated. The ST2.5 QUATTRO Spring Din Rail Terminal Block has passed rail industry qualification (5g shock, vibration), some of the toughest tests out there. It meets strict fire safety codes, and its design prevents unsafe overloads. This certification portfolio reduces your project’s approval risk and liability.

The value is locked in through manufacturing. Each ST2.5 QUATTRO Spring Din Rail Terminal Block uses premium PA and high-conductivity brass, formed and assembled with precision automation to eliminate unit-to-unit variation. Final batch testing is the gatekeeper. Therefore, specifying the ST2.5 QUATTRO Spring Din Rail Terminal Block is an investment in mitigating downtime, safety risks, and maintenance costs over your system's lifetime.
