Why Choose the ABB E2.2H/MS 800 4p WMP Switch Disconnector?
The ABB E2.2H/MS 800 4p WMP, order code 1SDA073526R1, is a high-performance four-pole withdrawable air switch disconnector from the ABB SACE Emax 2 family, engineered for dependable switching and electrical isolation in demanding low-voltage power distribution systems. Built on the Emax 2 E2.2 platform, it combines an 800 A continuous-current rating with the enhanced short-time withstand capability of the H performance level.
The E2.2H/MS is a switch-disconnector configuration intended primarily for switching and isolation rather than automatic overcurrent protection. The 1SDA073526R1 is supplied as the withdrawable moving part for use with the appropriate Emax 2 fixed part, allowing convenient disconnection for inspection, servicing and maintenance.
With a rated uninterrupted current of 800 A, a rated operational voltage of 690 V AC and a rated short-time withstand current of 85 kA for 1 s, the E2.2H/MS provides robust performance for high-fault-level distribution systems. Its four-pole configuration with a 100% rated neutral pole supports comprehensive switching and isolation in suitable three-phase four-wire installations.
Key Advantages
- High-performance 800 A air switch disconnector for low-voltage power distribution.

Reliable High-Current Switching and Isolation
ABB Emax 2 /MS switch disconnectors provide dependable switching and electrical isolation of low-voltage power circuits. Unlike an automatic Emax 2 air circuit breaker equipped with a protection trip unit, the /MS configuration is intended primarily to establish, carry, interrupt and isolate the electrical path within a coordinated power distribution system.
The withdrawable E2.2H/MS architecture allows the moving part to be separated from its compatible fixed part, supporting efficient inspection, servicing and equipment replacement. Combined with its 800 A current rating and 85 kA one-second short-time withstand capability, the 1SDA073526R1 is particularly suitable for demanding low-voltage distribution assemblies.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power distribution systems.
- Commercial and infrastructure electrical installations.
- Four-pole circuit isolation and sectionalising.
- Withdrawable switchgear requiring maintenance flexibility.
- OEM switchgear and power distribution assemblies.
