The ABB E2B/MS 1600 3P W MP, order code 1SDA058959R1, is a SACE Emax air switch disconnector moving part designed for high-current switching and isolation in low-voltage power distribution systems. Built on the ABB E2 frame, this three-pole device provides a rated uninterrupted current of 1600 A and forms the moving part of a withdrawable SACE Emax installation.
The E2B/MS 1600 combines ABB's service-friendly withdrawable architecture with the B short-circuit performance level. It provides a rated short-time withstand current of 42 kA for 1 s and 42 kA for 3 s, together with a rated short-circuit making capacity of 88.2 kA peak, supporting dependable isolation in demanding industrial distribution systems.
Rated for operation up to 690 V AC or 250 V DC, with a rated insulation voltage of 1000 V and rated impulse withstand voltage of 12 kV, the E2B/MS 1600 provides robust electrical performance for engineered switchboards. As an ABB /MS switch disconnector, it retains the Emax architecture and accessory possibilities while operating without an overcurrent trip unit, making it suitable where circuit protection is provided separately.
The ABB E2B/MS is derived from the corresponding SACE Emax circuit-breaker architecture but does not incorporate an overcurrent trip unit. This makes it a dedicated switching and isolation solution for installations where protection is provided separately. Its AC-23A utilisation category also allows switching of motor loads and other highly inductive loads within the applicable ratings.
The withdrawable design provides an important maintenance advantage because the moving part can be disconnected and withdrawn from its corresponding fixed section. Combined with its 1600 A current rating, three-pole construction and 42 kA short-time withstand capability, the E2B/MS 1600 is well suited to demanding industrial and infrastructure power distribution assemblies.
