Lovato GL0500C1 IEC/EN three-pole switch disconnector 500A

Why Choose the GL0500C1?

The Lovato GL0500C1 switch disconnector delivers robust, compliant isolation for demanding AC installations. This three-pole unit provides a 500 A IEC conventional free air thermal current (Ith) with a rated insulation voltage Ui of 1000 V and 12 kV impulse withstand. Designed for screw on plate installation, the GL series offers dependable manual switching aligned to IEC/EN 60947-3 and IEC/EN 60947-1.

It maintains 500 A operating current across AC21A and AC22A duties up to 690 V, and AC23A to 690 V, with 200 A at 1000 V. Rated operational power reaches 250 kW at 400 V and 500 kW at 690 V (AC23A). With 80 kA conditional short-circuit rating when protected by gG/500 fuses, plus 10,000-cycle mechanical life, it supports reliable service in harsh industrial environments.
