Why Choose the ABB E4H/MS 4000 4P F HR Switch Disconnector?
The ABB E4H/MS 4000 4P F HR, order code 1SDA059000R1, is a heavy-duty SACE Emax air switch disconnector engineered for high-current switching and isolation in low-voltage power distribution systems. Built on the ABB E4 frame, this four-pole unit provides a rated uninterrupted current of 4000 A and uses a fixed installation format with rear horizontal terminals.
The E4H/MS 4000 combines the proven SACE Emax architecture with the H performance level. It provides a rated short-time withstand current of 100 kA for 1 s and 75 kA for 3 s, together with a rated short-circuit making capacity of 220 kA peak, delivering substantial withstand capability for demanding industrial power distribution systems.
Rated for operation up to 690 V AC, with a rated insulation voltage of 1000 V and rated impulse withstand voltage of 12 kV, the E4H/MS 4000 is designed for substantial low-voltage distribution duties. ABB /MS switch disconnectors provide dedicated switching and isolation without an overcurrent trip unit, making this model suitable for systems where circuit protection is provided separately.
