Lovato GLC0315C1 IEC/EN three-pole changeover switch 315A

Why Choose the GLC0315C1?

Engineered for demanding power transfer duties, the Lovato GLC0315C1 is a three‑pole changeover switch certified to IEC/EN 60947 standards. With AC operating voltage type and AC‑23A performance, it delivers 315 A switching capability across 400, 500 and 690 V applications. The GLC0315C1 SKU is ideal for industrial panels requiring reliable source selection and isolation, combining robust construction with straightforward screw‑on‑plate installation for efficient panel integration.

Performance is underpinned by Ui 1000 V and Uimp 12 kV, with 100 kA conditional short‑circuit when protected by gG/315 fuses. At 400 V AC‑23A it offers 2500 A making and 2000 A breaking, while power dissipation is limited to 6.5 W per pole. Built for longevity with 20,000 mechanical cycles, it features 15–22 Nm terminal torque, operates from −25 to +55 °C, and is rated up to 3000 m altitude.
