ABB SACE Isomax S4

3 Pole 250 Amp

600 VAC Circuit Breaker

The SACE Isomax S family is divided into eight basic sizes from S1 to S8 with rated uninterrupted currents from 125 to 3200A. The types of devices consists of fixed, plug-in and withdrawable version circuit-breakers with eight levels of ultimate rated breaking capacity from 10 to 200kA (380-415V) identified by the letters B, N, S, H, L, V, X.
In the series, there are circuit-breakers available for alternating current and direct current distribution, current-limiting circuit-breakers, circuit-breakers for motor protection, switch-disconnectors, circuit-breakers for applications with voltages up to 1000V and residual current circuit-breakers as well as a specific range which complies with the North American UL489 and CSA C22.2 Standards.
The SACE S4, S5, S6, S7, S8 circuit-breakers can be equipped with microprocessor-based maximum current releases: PR211/P, PR212/P and PR212/MP (with functions suitable for motor protection).
The SACE Isomax S 1, S2, S3, S5 and S6 circuit-breakers can be equipped with thermomagnetic maximum current releases or Only Magnetic protection for instataneous protection.
