Lovato GL0315C1 IEC/EN three-pole switch disconnector 315A

Why Choose the GL0315C1?

Engineered for reliable isolation, the Lovato GL0315C1 three-pole switch disconnector (SKU GL0315C1) delivers 315 A IEC Ith for AC systems with Ui 1000 V and Uimp 12 kV. Designed for straightforward panel integration, it mounts by screws on plate or on a 35 mm DIN rail, providing a robust isolator for power distribution and control assemblies, and conforms to IEC/EN 60947-3 and 60947-1.

High utilisation category performance includes Ie 315 A for AC21A/AC22A, and AC23A 315 A at 400 V, 250 A at 500-690 V, and 135 A at 1000 V. It offers 2,500 A making and 2,000 A breaking capacity, 100 kA conditional short-circuit rating (gG/315 fuse), 20,000-cycle mechanical life, and secure terminations for 70 to 185 mm² conductors at 15 to 22 Nm.
