Why Choose the ABB E6H/E/MS 6300 3P Fixed 750 V DC Switch-Disconnector?
The ABB E6H/E/MS 6300, order code 1SDA058919R1, is a heavy-duty SACE Emax DC switch-disconnector designed for high-current switching and isolation in demanding direct-current power distribution systems. This model combines a 6300 A rated uninterrupted current with a 750 V DC operating rating and three-pole fixed construction.
As part of the ABB SACE Emax E6H/E/MS range, the device provides switching and isolation rather than integral electronic overcurrent protection. Its high-current E6 platform and 65 kA rated short-time withstand current make it suitable for substantial DC distribution systems where circuit protection is coordinated separately.
The E6H/E/MS 6300 3P F HR 750V DC configuration features three poles, fixed (F) installation and horizontal rear (HR) terminals. This arrangement is particularly suited to permanent high-current switchboard installations where robust rear busbar connections and dependable DC isolation are required.
