RIC installation contactors are versatile electromagnetic switching devices designed to reliably switch various types of electrical loads, such as lighting systems, heating, air conditioning, motors, or pumps. They have a rest position and can safely switch, conduct, and interrupt currents under normal operating conditions, as well as in overload situations. The double-break contacts interrupt the circuit at two points simultaneously, reducing contact wear, improving arc suppression during switching, and thus ensuring a particularly long service life.
