AC and DC contactors up to 3,000V and 2,000A
Building upon our experience in railway technology, Schaltbau produces highly reliable, outstanding contactors for all fields of use in which a load circuit has to be switched on and disconnected securely. Designed to IEC specifications, our wide variety of AC and DC contactors in stock range from contactors for low-voltage devices, such as batteries, through to high-voltage power contactors up to 3,000 V and 1,100 A.
Snap-action Switches
Snap-action switches, often called microswitches or limit switches, are electromechanical devices with a unique design that enables rapid actuation. These switches operate on a “snap-action” mechanism, meaning they quickly change state when a threshold of force is applied to the actuator. This distinctive characteristic makes them ideal for safety applications that require swift, precise switching.
Connectors
Connectors must ensure reliable transmission of energy and signals – coping with high voltages, harsh environments, and the rough conditions of rail traffic. Connectors from Schaltbau are specifically designed to meet these requirements: Where the safety and health of human beings depend on technology, as in transportation, mechanical engineering, lighting, food processing, battery charging, mining, or offshore operations, the rugged, heavy-duty connectors from Schaltbau are the first choice.
