With two frame sizes (P2C and P3C), SACE Otomax covered models with uninterrupted rated current Iu from 1000 to 5000A and guaranteed high performance both in alternating current (up to 660V AC) and in direct current (up to 500V DC). It included the K series of thermal relays, which were suitable for motors protection.
These circuit breakers introduced the first electronic opening relays: the S series.
