ABB moulded-case low-voltage circuit-breakers offer performance features that meet the full spectrum of application requirements, from small users through to large industrial electricity distribution installations.
The actual Isomax range will be replaced progressively by the new Tmax range.
The Tmax circuit-breakers T1..T5 represent the new series of ABB SACE moulded-case circuit-breakers for low voltage applications up to 630 A.
These devices guarantee a very high level of performance with reduced overall dimensions, easy installation and an increasing guarantee of safety for the operator with their reinforced insulation. The Tmax series circuit-breakers are specially indicated for secondary distribution in alternating and direct current and offer special solutions for every application requirement.
