Three new A1, A2 and A3 frames with maximum current ratings of 125A, 250A, and 630A each make up the new SACE FORMULA family. There is a fixed variant with front terminals for each of the three frames. For faster circuit-breaker activation, the protective trip unit has fixed thermal and magnetic threshold values.
Selection is made simple and accurate in this method.
Installation is simplified, and thanks to easy and rapid fixing operations and set-up, the circuit-breaker is ready for use immediately.
