GAZ100CT4B - 4P SWITCH 100A-ENCLOS BLACK HAND.PADLOCK

Why Choose the GAZ100CT4B?

Designed for dependable isolation, the Lovato GAZ100CT4B switch disconnector delivers secure on-load switching in a rugged IP65 non-metallic enclosure. This four-pole, enclosed unit features a rotating black handle and a 100 A Ith rating for AC applications. Compact dimensions of 175 x 210 x 99 mm simplify panel or site mounting while providing ample internal space for terminations, making it ideal for industrial power control and maintenance isolation points.

Built to IEC/EN 60947-3 and 60947-1, the GAZ series offers Ui 1000 V and Uimp 8 kV, with AC21/AC22 ratings to 100 A and AC23A up to 47 A at 690 V. It withstands conditional short-circuit currents of 50 kA (gG100 fuse) and achieves 30,000 mechanical and electrical cycles. Wide -25 to +55 °C operating range, IP65 protection and 4 to 70 mm² terminals support demanding UK industrial environments.
