Lovato 7GN12R254U GN12 series four-position, four-pole front-mounted rotary cam switch for AUTO, OFF, BYPASS and frequency-converter mode selection in industrial control systems.
£21.66
The Lovato 7GN12R254U is a specialised four-position, four-pole rotary cam switch designed for industrial control applications requiring selection between AUTO, OFF, BYPASS and FREQ.CONV operating modes. Part of the Lovato GN series, it provides a compact and dependable manual interface for selecting the required operating state of a machine or motor-control system.
With its dedicated four-position switching arrangement, the 7GN12R254U is particularly suited to installations incorporating a frequency converter or variable speed drive alongside a bypass circuit and automatic control system. The clearly defined selector positions allow an operator to choose the required control mode from a single front-mounted rotary switch.
The GN12 platform has a 16 A conventional free-air thermal current rating and uses silver-alloy, double-break contacts for reliable switching performance. The switch is supplied in a front-mounting U version with black handle and 48 × 48 mm front plate, making it suitable for integration into control panels, switchboards and machinery operator interfaces.
Industrial motor-control systems frequently use a frequency converter to provide adjustable motor speed, controlled acceleration and process optimisation. A bypass arrangement can provide an alternative operating path where the application and electrical design permit it. A dedicated rotary cam selector such as the Lovato 7GN12R254U gives the operator a clear physical interface for selecting between the available control modes.
The AUTO/OFF/BYPASS/FREQ.CONV arrangement allows the required state to be selected deliberately, while the four-pole cam mechanism can simultaneously switch several associated control circuits according to the switch's internal contact programme. This makes the 7GN12R254U particularly useful in motor-control panels and automation systems incorporating both frequency-converter and bypass functionality.
