GAZM063SAET8 - 4P 63A CHANGEOVER METAL ENCLOSED SWITCH

Why Choose the GAZM063SAET8?

The Lovato GAZM063SAET8 is a four-pole I-0-II line changeover switch supplied in a robust IEC/EN IP65 metal enclosure for dependable source switching. Rated Ith 63 A with Ui 1000 V and Uimp 8 kV, it supports AC duty to 690 V across AC21A, AC22A and AC23A categories. A compact 150×200×120 mm footprint simplifies panel retrofits, while the front selector provides clear I-0-II positions for straightforward operation.

Designed for longevity, the mechanism offers 100,000 mechanical cycles and 15,000 electrical cycles (AC21A). Terminals accept 0.75–16 mm² conductors and tighten to 1.8–2 Nm for secure connections. Operates from −25 to +55 °C up to 3000 m altitude. With a conditional short-circuit rating of 10 kA (gG63 fuse) and low 2.9 W per-pole dissipation, it suits demanding industrial changeover tasks.
