Lovato GLC0315T4C1 IEC/EN four-pole changeover switch 315A

Why Choose the GLC0315T4C1?

The Lovato GLC0315T4C1 is a GLC series four‑pole changeover switch for AC networks, designed for dependable load transfer in industrial panels. Rated Ith 315 A with AC23A operating current of 315 A at 400, 500 and 690 V, it offers Ui 1000 V and Uimp 12 kV. Compact, robust, and simple to install with screw‑on‑plate mounting.

Engineered for demanding AC23A duties, this changeover switch delivers 140 kW at 400 V and 250 kW at 690 V, with 2500 A making and 2000 A breaking capacity at 400 V. It supports a conditional short‑circuit current of 100 kA with gG/315 fusing, provides 20,000 mechanical cycles, 15–22 Nm terminal torque, and operates from −25 to +55 °C up to 3000 m altitude, conforming to IEC/EN 60947 standards.
