GAZ040DT4 - PLASTIC ENCL ISOLATOR 40A 4P PHOTOVOLTAIC R/Y HANDLE

Why Choose the GAZ040DT4?

The Lovato GAZ040DT4 switch disconnector delivers dependable DC isolation for photovoltaic installations. Supplied in an IP65 plastic enclosure with a prominent red/yellow handle, it is designed for safe, visible disconnection. With 2 poles, 40 A thermal current and suitability up to 1000 V DC, the GAZ040DT4 supports robust string-level isolation while maintaining compact dimensions of 175 x 210 x 99 mm for flexible mounting in demanding environments.

Built for reliability, this enclosed switch disconnector meets IEC/EN 60947-1 and 60947-3, with Ui 1500 V and 8 kV impulse withstand. IP65 protection resists dust and water jets, while terminals accept 1–10 mm² conductors tightened to 1.2–1.6 Nm. Operating from -25 to +55 °C and suitable up to 3000 m altitude, it offers durable performance for commercial and industrial solar projects.
