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.

STTB2.5 Spring Din Rail Terminal Block

The CHTAR STTB2.5 Spring DIN Rail Terminal Block addresses this challenge through its space-saving, dual-level construction and outstanding compatibility with various wiring configurations. Its spring-clamp connection points accommodate a broad range: solid conductors from 0.08 mm² all the way to 4.0 mm² (AWG 28-12), and stranded wires up to 2.5 mm²—with or without ferrules. This means you can handle everything from sensitive sensor signals to more substantial control power in one unified component, simplifying your panel layout dramatically. For projects demanding both density and flexibility, it's an efficient solution. Reach out to us to discuss how it can meet your specific wiring needs.

ST 2.5 Spring Din Rail Terminal Block

As engineers, we balance the need for absolute reliability with the pressure to deploy systems faster. That balance drove the design of our ST 2.5 Spring DIN Rail Terminal Block. Think of it as merging the proven reliability of a DIN rail platform with the rapid installation of a spring-clamp. We focused on making the clamp mechanism itself exceptionally durable—because a spring connection is only as good as its material and design. The result is a terminal block that’s perfect for control panels in infrastructure or automation, where you need to make hundreds of connections quickly without second-guessing their long-term stability. It’s about working smarter.Reach out, and we’ll walk you through the specs and test data.
