Description

The T2 breaker family ranges from 15 through 100 A. The T2 trip units are non-interchangeable and use the very latest technology in electromagnetic relays for over current trip protection as well as a version with microprocessor based electronic trip unit. Thermal overload protection is provided by heat sensitive bimetals. State of the art construction in contacts and arcing chambers aid in limiting damaging fault currents through the protected circuits.

Applications

For Power Distribution. All versions of the Tmax family are suitable for reverse feed applications
