2 SACE Tmax Moulded-case circuit-breakers | ABB ABB | SACE Tmax Moulded-case circuit-breakers 3
A single family of moulded-case circuit-breakers up to 3200 A
Tmax moulded-case circuit-breakers guarantee an extremely
high performance level while being progressively smaller in
size, simple to install and able to provide increasingly better
safety guarantees for the operator.
In addition to being ideal for the secondary distribution
of alternmate and direct current, they feature dedicated
solutions for all application requirements.
Moulded-case circuit-breakers can be used in low voltage
civil and industrial installations with 1 to 3200 A operating
current. The Tmax family includes 9 circuit-breaker sizes in
three- or four-pole versions:
- XT1, XT2, XT3 and XT4 up to 250A;
- T4, T5 and T6 up to 1000A;
- T7 and T8 up to 3200A.
Up to 250 A Up to 1000 A Up to 3200 A
The ultimate short-circuit breaking capacity (Icu) at 415V
ranges from 18kA to 200kA, or up to 100kA for 690V.
The following ranges are available:
- Circuit-breakers for AC and DC power distribution;
- Circuit-breakers for zone selectivity;
- Circuit-breakers for motor protection;
- Circuit-breakers for up to 1150V AC and 1000V DC
applications;
- Switch-disconnectors.
All Tmax circuit breakers can be enhanced with a vast range
of standardized accessories. This convenience not only cuts
down on inventory, but creates an extremely flexible and easily
managed solution.
Tmax circuit-breakers can be equipped with thermomagnetic,
solely magnetic or electronic trip units;, all of which are
interchangeable.
Since assembly instructions are simple, trip units can quickly
and easily be replaced; even in the field.
All this makes the circuit-breakers very easy to operate with
considerable savings due to rationalized stock management.
