£83.33
The Lovato 7GN3253U is a robust 32 A three-pole rotary cam changeover switch designed for manual switching in industrial machinery and electrical control applications. As part of the Lovato 7GN rotary cam switch series, it uses switching diagram 53 and is configured for three-pole changeover and two-speed motor starting with separate windings.
The 7GN3253U incorporates three switching elements and uses Lovato's U mounting form for front mounting with a black operating handle. Its 65 × 65 mm front plate provides a practical operator interface for integration into electrical control panels and machinery.
With an IEC conventional free-air thermal current of 32 A, a rated insulation voltage of 690 V and a rated impulse withstand voltage of 6 kV, the 7GN3253U provides dependable electrical switching performance. A mechanical life of 5 × 106 cycles supports reliable operation in demanding industrial control applications.
Rotary cam switches provide a direct mechanical method of selecting electrical circuit configurations and controlling motor circuits. Their positive rotary operation makes them suitable for industrial machinery where operators require clear and dependable manual switching from the front of a control panel.
The Lovato 7GN3253U uses switching diagram 53, providing three-pole changeover functionality configured for two-speed motors with separate windings. Its 32 A thermal current rating, three switching elements and front-mounted black handle make it a practical choice for machinery, control panels and industrial motor-control installations.
