Tmax PV: photovoltaic range

The average power generating capacity of photovoltaic systems is increasing day by day throughout the world. When the power generated by a photovoltaic production system exceeds a certain level and use of a low voltage switchdisconnector is required, Tmax PV moulded-case switchdisconnectors are suitable for the purpose. Tmax PV is the latest product to the 0 to 1600 A Tmax T family for use up to 1100 V DC at 1150 V DC rated insulation voltage.

Tmax VF: Tmax for applications at variable frequency

Experience gained in designing moulded-case and air circuit-breakers, on-going collaboration with the major manufacturers of wind turbines and ABB’s particular interest in power generation from renewable sources have led to a pioneering solution for protecting variable frequency installations comprising Tmax VF moulded case circuit-breakers and Emax VF air circuit-breakers.

Tmax T 50°C

ABB SACE has developed a new family of moulded-case circuit-breakers called Tmax T equipped with a thermomagnetic trip unit, able to convey 100% of the rated current even when used at 50°C ambient temperature.
