Miniature Circuit Breakers
Metaltex miniature circuit breakers are DIN-rail mounted thermomagnetic devices designed to protect low-voltage circuits in automation and distribution panels against overloads and short circuits. They are available in 1-, 2-, and 3-pole configurations with rated currents up to 125 A. Operating primarily according to the C-curve, they are ideal for withstanding transient surges from moderate inductive loads without nuisance tripping. Versions are available with rated breaking capacities of 3 kA, 6 kA, or 10 kA, in compliance with ABNT NBR/IEC standards and holding the relevant safety certifications. A variety of accessories is available.
