This is a ground modular terminal block designed for use with feed-through terminal blocks of the same shape. An end cover is required for insulation when operating at voltages greater than 320 V. The terminal features screw connections, supports two connection points, and accommodates wire cross sections from 0.14 mm² to 1.5 mm² (AWG 26 to 16). It has a width of 4.2 mm, is color-coded green-yellow for grounding purposes, and is mounted using NS 15 mounting type.
