1SDA059040R1 ABB E3H/EMS 3200 4P 1150V AC W MP Switch Disconnector

Why Choose the ABB E3H/EMS 3200 4P 1150V AC W MP Switch Disconnector?

The ABB E3H/EMS 3200 4P 1150V AC W MP, order code 1SDA059040R1, is a high-current SACE Emax air switch disconnector moving part designed for demanding AC power distribution and isolation applications. This specialised E3H/EMS configuration combines a 3200 A rated uninterrupted current, four-pole construction and operation at up to 1150 V AC.

This version is supplied as the withdrawable moving part (W MP) of the switch-disconnector assembly. Its slide-in withdrawable construction is designed for integration with the corresponding compatible fixed portion, supporting circuit isolation, inspection and maintenance in high-current electrical switchgear.

With a 3200 A rated operational current, 1250 V insulation voltage, 12 kV impulse withstand voltage and 30 kA short-time withstand current for 1 s, the E3H/EMS 3200 provides robust electrical performance for specialised high-current installations operating above conventional 690 V AC distribution levels.

Reliable High-Voltage AC Isolation for Power Distribution

Air switch disconnectors provide controlled switching and electrical isolation of power circuits without incorporating the overcurrent protection function of a conventional circuit-breaker trip unit. Withdrawable construction also enables the moving part to be separated from the fixed assembly, supporting maintenance and isolation procedures in large electrical distribution systems.

The ABB E3H/EMS 3200 is specifically configured for systems operating at up to 1150 V AC. Its combination of a 3200 A current rating, four-pole construction, 30 kA short-time withstand capability and withdrawable SACE Emax architecture makes it suitable for specialised industrial switchgear where high current capacity and dependable four-pole isolation are required.

Typical Applications

• High-current industrial AC power distribution systems.
• 1150 V AC switchgear and distribution assemblies.
• Main incoming and feeder isolation applications.
• Four-pole 3200 A electrical distribution systems.
• Withdrawable industrial switchboards requiring serviceable isolation equipment.
• Manufacturing, infrastructure and process-industry electrical installations.
