A family of high-density spring cage terminal blocks utilizes a new "mini spring" design that reduces overall size without giving up any features. The ST terminal blocks have a flexible, dual-channel, push-in jumper system that can handle chain and skip bridging using 2-, 3-, 4-, 5-, 10- or 20-position jumpers.
A generous wire entrance eliminates the need to switch to a larger terminal block when ferrules are used. A large center marking makes for easy access and readability, according to the company, while end marking aids in labeling each termination point.
