The Tmax T1. T3 and Isomax S3 150. S3 225 with fixed thermal

and magnetic threshold, S5 and S6 thermomagnetic with adjust

able thermal and magnetic threshold are available for protection

of both AC and DC circuits.

Apart from the circuit breakers indicated above, for alternating

current networks, the Tmax T2. Isomax S4. S5. S6. S7 and S8

circuit breakers with electronic microprocessor-based trip unit are

also available.

HIGH LIMITATION

Thanks to its high performances, Tmax T1. as well as T2 and

T3. is used with great advantages in all the applications where a

high limitation of the value of the specific let-through energy

and the peak of the short circuit-current allows a smaller size of

cables, busbars and all the devices on the loadside of the circuit breaker.

ACCESSORIES

The same accessories as the other two circuit breakers in the

family can be mounted on Tmax T1. with great benefits in

terms of reduced stock and simple selection. Even the details

have not been overlooked, such as the new flange (ABB SACE

patent) which avoids securing with screws on the door and

compensates any defects in sheet  punching.
