Tmax and Isomax
Power distribution circuit-breakers
General characteristics
The ABB family of moulded case circuit-breakers - Tmax and Isomax - is divided into different, perfectly
integrated, ranges (Tmax T1B 1p, T1, T2, T3, T4, T5 and Isomax S6 and S7), able to cover a range of service
currents from 1 to 1600 A.
The power distribution circuit-breakers are available in the fixed, plug-in or withdrawable, three-pole and
four-pole versions.
The Tmax T1 circuit-breaker is also available in the single pole
Tmax T1B 1p version, with breaking capacities of 25 kA at 220/230 V AC.
Interchangeability of the releases
The Tmax T4 and T5 circuit-breakers can be fitted either with thermomagnetic, magnetic only or electronic
releases, which are all interchangeable with each other. In fact, thanks to the simplicity of their installation,
the type of release can be replaced rapidly even by the end user, according to their requirements and needs:
in this case, correct assembly remains the responsibility of the user himself. All this means increasing the
flexibility of use of the circuit-breakers, with considerable savings thanks to the better rationalization of
stock management.
Conformity with Standards
The moulded-case circuit-breakers and their accessories conform to the IEC 60947-2 international
Standards and comply with the EC “Low Voltage Directives (LVD) no. 73/ 23 EEC” and “Electromagnetic
compatibility Directives (EMC) no. 89/336 EEC”.
ABB’s Quality System conforms to the ISO 9001 International Standard and to the equivalent European
EN ISO 9001 and Italian UNI EN ISO 9001 Standards. The certifying Body is the Italian Shipping Register
(RINA - QUACER): ABB has reached its third qualification confirmation. The ABB Test Room is accredited
by SINAL.
The apparatus conforms to the prescriptions of the on-board installations and approvals by the major
Shipping Registers are in progress.
