The 3213768 is a ground modular terminal block featuring a tool-free push-in connection system. It is a three-level block with six connection points, accommodating a conductor cross-section from 0.14 mm² to 1.5 mm² (AWG 26-14). With a narrow width of 3.5 mm, it is designed for mounting on NS 35/7,5 and NS 35/15 DIN rails and is rated for a nominal voltage of 500 V and a maximum load current of 15 A. The compact design and front connection enable wiring in confined spaces, and its testing for railway applications makes it suitable for demanding industrial environments.
