ABB Sace 1SD AO 13785 R1 S3-S4-S5 Shunt Opening Release 220-250V DC

The SACE Isomax S series of moulded-case circuit-breakers conforming to the IEC 60947-2 Standard, is divided into eight basic sizes, with rated uninterrupted currents from 125 to 3200 A and breaking capacities from 16 to 120 kA (380/415 V).

Selection of the size allows the basic electrical characteristics to be identified simply and immediately, whereas selection of the over current release depends on the type of application required.

SACE Isomax S circuit-breakers can be used in ambient conditions where the temperature in the surrounding atmosphere varies between -25 °C and +70 °C and stored in ambients with temperatures between -40 °C and +70 °C.

The circuit-breakers fitted with thermo magnetic over current release have their thermal element set for a reference temperature of +40 °C.

SACE Isomax S1, S2, S3, S5, and S6 circuit-breakers can be fitted with thermo magnetic releases and are used for protection of alternating current networks with the S1, S2, and S3 circuit-breakers (for applications from 10A to 250A) and in direct current with the S1, S2, S3, S5, and S6 circuit-breakers (from 10A to 800A).
