JXB-ST JXB-S EKF PROxima spring terminal blocks are installed on 35 mm DIN rails and are designed for use in distribution boards – for connecting and branching phase, neutral, and grounding conductors of various cross-sections. A special advantage of these terminals is the screwless conductor fastening: spring-loaded self-tightening contacts are used. The conductor is fed from the top of the terminal. To disconnect the conductor, it is necessary to press the spring with a screwdriver through the hole located at the top of the terminal. Designed for use in AC circuits with a voltage up to 800 V and a frequency of 50 Hz. Terminals are made of fire-resistant polyamide in the following colors: gray, yellow-green (earth). Additionally, side covers for closing the contacts of the end terminal, jumpers for branching conductors, markers, etc., are produced for the terminals.
