KISSLING is the first manufacturer worldwide focusing on a non-gas-filled ceramic contact chamber for a high-voltage power relay. KISSLING addressed the biggest challenge, minimizing the burning time of the switching arc, by using a highly-dynamic and efficient propulsion system. This ensures a first-class product with the extended lifecycle, high quality and reliability you've come to expect from KISSLING.
The ongoing push towards hybrid-electric and full-electric vehicles in the automotive industry has lead to the adoption of high-voltage electrical systems, which are essential to achieve power levels similar to internal-combustion engines. However, in switching devices this results in a significant arc when switching the load which over time destroys the contacts. Therefore, the main task for switching device manufacturers is to minimize the burning time of the switching arc. The new KISSLING high-voltage relays accomplish this and make the technology safe and manageable.
This single coil system relay features high shock and vibration resistance resulting from careful design and an optimized magnetic circuit. The sealing technology used in these relays meets or exceeds both the IP67 and IP6K9K (Steam pressure cleaning) protection standard. This series of relays is well suited for various applications in severe conditions on commercial vehicles, buses, construction & agricultural vehicles, aircraft, ground support equipment and lift trucks.
Other important advantages are low heat generation in the contact area based on low contact voltage drop, a compact design, low holding current, silver alloy contact material and the use of mechanical and high thermal stability insulating compounds. Both the terminals and housing are protected against corrosion.
