Terminal block
JXB series Screw Clamp terminal blocks are known and accepted worldwide. The screw clamp technology is preferred because it offers top reliability with the best clamping force. Screw clamp terminal blocks have a larger electrical contact area, the lowest contact resistance, the highest pull out force, and the ability to handle multiple wires and larger wire ranges. Factory studies have indicated that nuisance electrical downtime is traced back to nothing more than loose or intermittent connections caused by insufficient clamping forces and metal bodies not protected from corrosion. In order to eliminate the possibility of these types of problems, look to manufacturers who offer wire-clamping mechanisms that are designed to prevent screw back-out. In addition, a nickel-plated copper alloy is the preferred choice over steel because it is a better conductor, has better thermal expansion properties and offers better corrosion resistance.
