ABN SHU Switch 3-Pole 40A XKS340-5

The ABN SHU-Schalter XKS340-5 is a high-quality 3-pole load disconnector / isolator switch designed for industrial and commercial applications. With a rated current of 40 A and operational voltage up to 690 V AC, it ensures reliable switching and isolation of electrical circuits. This switch is ideal for use as a main switch or maintenance disconnector in distribution boards and control panels.

Advantages

Robust construction with high short-circuit withstand capacity (1.2 kA for 1s) and breaking capacity (3 kA). Complies with IEC/EN 60947-3 standards for safety and performance. Easy DIN rail mounting (35 mm) with 3 module width saves space. Screw terminals accommodate conductors up to 25 mm² for flexible installation.
