1SDA059038R1 ABB E3H/E MS 2500 4P 1150V AC W MP Switch Disconnector

Why Choose the ABB E3H/E MS 2500 4P 1150V AC W MP Switch Disconnector?

The ABB E3H/E MS 2500 4P 1150V AC W MP, order code 1SDA059038R1, is a high-current four-pole withdrawable switch disconnector moving part from the ABB SACE Emax range, designed for dependable switching and isolation in demanding AC power distribution systems. With a rated uninterrupted current of 2500 A and a maximum rated operational voltage of 1150 V AC, it is engineered for industrial installations requiring reliable high-current isolation at elevated AC voltages.

This E3H/E MS model combines the robust ABB SACE Emax E3 frame with H-level performance and a serviceable withdrawable architecture. The W MP designation identifies the moving part of the withdrawable version, enabling the switching unit to be withdrawn from its compatible fixed section for inspection, maintenance or replacement within suitable Emax switchgear.

The E3H/E MS 2500 provides a 2500 A rated uninterrupted current, 1150 V AC rated operational voltage, 1250 V rated insulation voltage and 12 kV rated impulse withstand voltage. Its rated short-time withstand current of 30 kA for 1 s supports dependable operation in demanding distribution environments, while the four-pole configuration enables coordinated switching and isolation of four conductors.
