1SDA115396R1 ABB E4.2S MS/DC-E 1600A 1500V 4-Pole Fixed Switch Disconnector

Why Choose the ABB E4.2S MS/DC-E 1600 A 1500 V Switch Disconnector?

The ABB 1SDA115396R1 E4.2S MS/DC-E is a high-current 1600 A, 1500 V DC, four-pole fixed switch disconnector from the SACE Emax 2 MS/DC-E range. Engineered specifically for high-voltage DC distribution, it provides dependable isolation and switching functionality for demanding industrial and energy applications.

Designed around the proven Emax 2 E4.2 frame, this S-performance version combines a rated uninterrupted current of 1600 A with a rated short-time withstand current of 65 kA for 1 s. Its 1500 V DC capability makes it particularly suited to modern DC networks where conventional low-voltage switch disconnectors cannot provide the required operating-voltage capability.

The 1SDA115396R1 is the fixed, four-pole IEC version and is supplied without terminals, allowing the required connection arrangement to be configured for the installation. ABB's MS/DC-E architecture provides a dedicated Emax 2 solution for isolation in high-power DC systems while retaining the robust mechanical platform and accessory ecosystem associated with the Emax 2 family.
