The Sensata Technologies Airpax ATR20 supplementary circuit protector from Abacus Switch features a snap action, cantilevered, thermo-bimetal disk profile with silver alloy contacts, providing reliable ‘trip-free’ operation on short term overloads and short circuits up to the current rating specified. This mechanism is specifically designed to maintain a high contact force until the contacts break due to overload. The ATR20 is available in ratings from 0.5A to 20A at 240Vac / 50Vdc, with a breaking capacity of 1000A. It features UL, CSA, TUV and CE approvals.

Abacus Switch has also added the Sensata Technologies Airpax ATR11, aimed at power strips, single phase motors, transformers, solenoids and UPS. Available in current ratings from 0.5A to 16A at 250Vac / 50Vdc, the ATR11 is also able to break up to 1000A. The bimetallic strip design of the device is immune to high inrush currents and line transients. Its contacts open and close with a positive snap action, and the tripped state is clearly indicated by the protruding reset button. The ATR11 features UL, CSA and VDE approvals.
