Lovato GLC0160C1 IEC/EN three-pole changeover switch 160A

Why Choose the GLC0160C1?

The Lovato GLC0160C1 three-pole changeover switch delivers dependable source transfer for AC installations. With an IEC conventional free air thermal current (Ith) of 160 A and robust AC23A ratings of 90 kW at 400 V and 144 kW at 690 V, it handles demanding loads. Rated insulation voltage Ui 1000 V and impulse withstand Uimp 12 kV support reliable performance in industrial switchboards and panels.

Built for longevity and ease of installation, the GLC series device offers 20,000 mechanical cycles and secure screw-on plate mounting. Terminals accept 70–185 mm² conductors with a tightening torque of 15 to 22 Nm. A 100 kA conditional short-circuit rating (with gG/160 fuse) and compliance to IEC/EN 60947-3, 60947-6-1 and 60947-1 ensure robust protection across -25 to +55 °C and up to 3000 m altitude.
