Tmax XT

Tmax XT molded case circuit breakers offers extraordinary flexibility and completeness of range to simplify system designs and reduce inventory and procurement costs.
 
With current ratings up to 250A and a voltage rating of 600V, both alternating (AC) and direct (DC) current in the same breaker. This combined with extended breaking capacities, up to 200kA, gives Tmax XT molded case circuit breakers the ability to cover a full range of applications.
 
To ensure your design will fit customer requirements around the globe, the Tmax XT is globally certified UL/CSA/IEC with a wide range of naval registrations and much more.

Product Scope

Tmax XT1 is the smallest circuit breaker of the family, available in 3 and 4 poles version. Despite the reduced dimensions, Tmax XT1 reaches a breaking capacity value of 65kA at 480V.

 

Tmax XT2 is the high performing circuit breaker for applications up to 125A, available in 3 and 4 poles version with electronic and thermalmagnetic trip units. Five different breaking capacities are offered to customer, up to a maximum value of 150kA at 480V.

 

Tmax XT3 is the standard circuit breaker for applications up to 225A, available in 3 and 4 poles version. Two different levels of breaking capacities are available up to the maximum value of 35kA at 480V.

 

Tmax XT4 is the powerful circuit breaker for applications up to 250A. It is offered in five levels of breaking capacity, up to a maximum value of 150kA at 480V. Tmax XT4 can be fitted with thermalmagnetic and electronic trip units, even with energy metering. According to the different performance levels, 2, 3 and 4 poles versions are available.
