GAZ040B - 3P SWITCH 40A-ENCLOS-BLACK HAND.PADLOCK

Why Choose the GAZ040B?

Designed for reliable isolation in harsh conditions, the Lovato GAZ040B is a three-pole switch disconnector supplied in a robust IP65 plastic enclosure with a rotating black handle. Rated Ith 40 A with Ui 1000 V and Uimp 8 kV, it delivers dependable performance across industrial installations. Compact 100x168x97 mm dimensions streamline space planning while the enclosure keeps dust and water at bay for safe operation.

Performance is proven across duty categories: AC21A and AC22A up to 40 A, plus AC23A 40 A at 400 V and 25 A at 500/690 V. Mechanical life is 100000 cycles with electrical life of 100000 cycles (AC21A). Terminals accept 0.75 to 16 mm² conductors, tightened to 1.8 to 2 Nm. Operating temperature is -25 to +55 °C. Conditional short-circuit current is 10 kA with gG40 fuse. Compliant with IEC/EN 60947-3 and IEC/EN 60947-1.
