Lovato GLC0160T4C1 IEC/EN four-pole changeover switch 160A

Why Choose the GLC0160T4C1?

Lovato’s GLC0160T4C1 is a robust four‑pole changeover switch engineered for dependable AC load transfer in industrial panels. Rated Ith 160 A and compliant with IEC/EN 60947, this GLC series device ensures reliable switching performance and safety. The SKU GLC0160T4C1 features screw‑on‑plate mounting for straightforward installation, making it a strong choice for mains–generator changeover, isolation duties, and distribution boards where secure, repeatable operation matters.

Performance is assured with Ui 1000 V and Uimp 12 kV, plus AC‑23A power ratings of 90 kW at 400 V and 144 kW at 690 V. At 400 V AC‑23A it offers 1600 A making and 1280 A breaking capacity, and a 100 kA conditional short‑circuit rating with gG/160 fuses. Durable for 20,000 cycles, it suits 70–185 mm² conductors with 15–22 Nm torque, and operates from −25 to +55 °C up to 3000 m altitude.
