Why Choose the 7GN4053U?
Lovato’s 7GN4053U is a rotary cam changeover switch from the 7GN series, designed for reliable three‑pole switching at 40 A Ith. The U mounting form enables front mounting with a black handle and a compact 65×65 mm front plate. With IP40 frontal protection, 6 kV Uimp and an operating range of −25 to +55 °C, it delivers robust performance for front‑mounted panel applications.
Switching diagram 53 supports changeover control of two‑speed motors with separate windings across three poles. The 7GN round‑shaped contact block suits compact, front‑mounted panels. Conformity to IEC/EN/BS 60947‑1, 60947‑3 and 60947‑5‑1, plus UL60947‑4‑1 and CSA C22.2 n° 14, supports specification to recognised standards. A listed Sustainability certification complements its specification.
