GAZ016T4B - 4P SWITCH 16A-ENCLOS-BLACK HAND.PADLOCK

Why Choose the GAZ016T4B?

Lovato’s GAZ016T4B is an IEC/EN IP65 plastic enclosure switch disconnector designed for reliable four-pole isolation in AC systems. With a rotating black handle and 16 A rating, it supports AC21A/AC22A/AC23A operation at 400, 500 and 690 V. The compact 100x168x97 mm enclosure suits space‑constrained panels while delivering robust performance, including Ui 1000 V and Uimp 8 kV, for dependable on‑load disconnection and safe maintenance isolation.

Engineered for durability, this four-pole isolator offers 100000 mechanical and electrical cycles, with 160 A making and 128 A breaking capacity at AC23A 400 V. It carries a conditional short-circuit rating of 10 kA with gG16 protection and accepts 0.75–16 mm² conductors at 1.8–2 Nm torque. Operating from −25 to +55 °C up to 3000 m altitude, it complies with IEC/EN 60947-3 and IEC/EN 60947-1.
