Lovato GL0160C1 IEC/EN three-pole switch disconnector 160A

Why Choose the GL0160C1?

The Lovato GL0160C1 three-pole switch disconnector delivers dependable isolation for AC systems up to 160 A Ith. Built to IEC/EN 60947-3, it suits panel builders and maintenance teams needing safe, positive disconnection. Compact and versatile, it mounts by screw on plate or on a 35 mm DIN rail, simplifying integration in control panels, distribution boards and switchgear where reliable load breaking and clear off-position isolation are essential.

Engineered for tough environments, GL0160C1 offers Ui 1000 V and Uimp 12 kV, with AC23A making 1600 A and breaking 1280 A at 400 V. Rated operational power reaches 90 kW at 400 V and 134 kW at 690 V. It achieves 100 kA conditional short-circuit withstand, endures 20,000 mechanical cycles, and operates from -25 to +55 °C with 15–22 Nm terminal torque and 70–185 mm² conductors.
