Designed for railway applications per the product designation, it also carries an overvoltage category III rating — suitable for fixed-installation distribution boards where transient overvoltages are expected.
Mounts via the quick assembly system — snap-on to DIN rail, any position. At 72 mm wide (4 width units) and 76 mm deep (70 mm installation depth), it occupies standard panel space. The combined terminal top and bottom accept solid or stranded conductors from 0.75 to 35 mm²; tightening torque is 2.5 to 3.5 N·m.
Environmental and operational range
Halogen-free and silicon-free construction. Humidity tolerance: max 95% at 55 °C, derating to 55% at 70 °C and 35% at 75 °C. Neutral conductor switching is built in — no external link needed for the N pole.
