The IKA20-20/2NO 24V is an electromagnetic installation contactor designed for switching all categories of electrical load — lighting, motors, electric heating, and electronic equipment. Its 24V AC excitation coil is a common safety extra-low-voltage level used in building automation and control systems, while the 2-pole (2NO) configuration covers most single-phase switching tasks in a single DIN-rail module.

The contactor mounts on a standard 35 mm DIN rail and occupies just 1 modular distance, keeping panel space to a minimum. It is used in offices, shops, hospitals, sports facilities, production halls, and other public spaces where centralised load control is required.
