£15.68
The IMO CS20A-SD is a robust rotary cam switch for star delta motor starting applications designed for reliable manual control of three-phase motors in industrial automation, machinery and electrical control panel applications. As part of the IMO CS20A rotary cam switch series, it provides dependable switching performance, compact panel mounting and high-current capability for industrial motor control systems.
This specialised cam switch provides a 3-position star delta switching sequence with 0 / Y / Δ positions, allowing operators to manually control reduced-current motor starting arrangements. Its compact single-hole panel mounting design and legend plate compatibility make it suitable for motor control panels and industrial equipment.
With a 20 A AC contact rating, a 690 V AC maximum operating voltage and a star delta 3-position switching configuration, the IMO CS20A-SD is ideal for manual motor starting control, machinery applications and industrial electrical installations.
Star delta cam switches such as the IMO CS20A-SD provide a simple and effective manual method for controlling reduced-current motor starting sequences. By selecting star and delta operating positions, operators can reduce the initial starting current of suitable three-phase induction motors.
The IMO CS20A series is designed for machine builders, panel manufacturers and industrial engineers requiring durable manual switching components. Its compact design, high-current contacts and dedicated motor starting function make it suitable for demanding industrial installations.
