7GN4053P - 3P 3POS SWITCH GN4053P C/W HOUSING

Why Choose the 7GN4053P?

The Lovato 7GN4053P changeover switch is an enclosed rotary cam device from the 7GN series, providing 3‑pole changeover with a 40 A Ith rating. Housed in a 110 x 110 mm plastic enclosure with a black handle, it offers IP65 frontal protection. Its Switching diagram 53 configuration supports 3‑pole changeover for 2‑speed motor starting with separate windings.

Designated 7GN40, this unit has a rated impulse withstand voltage Uimp of 6 kV and an operating range of -25 to +55 °C. It conforms to IEC/EN/BS 60947‑1, 60947‑3 and 60947‑5‑1. Mounting form P identifies the plastic enclosure with black handle, and the 7GN series features a round-shaped contact block.
