Why Choose the ABB E4.2V/MS 3200 4p FHR Switch Disconnector?
The ABB E4.2V/MS 3200 4p FHR, order code 1SDA073459R1, is a high-performance four-pole air switch disconnector from the ABB SACE Emax 2 range, engineered for switching and isolation in demanding low-voltage power distribution systems. Based on the E4.2 frame and V performance level, this /MS device combines a substantial 3200 A rated uninterrupted current with very high short-time withstand capability.
Designed to satisfy the isolation requirements of IEC 60947-3, the E4.2V/MS provides a rated short-time withstand current of 100 kA for 1 s and 75 kA for 3 s. These ratings make it particularly suitable for high-power switchboards and industrial distribution systems where the isolating device must withstand severe prospective fault-current conditions.
This model is supplied as a fixed four-pole unit with rear horizontal terminals (FHR). It has a rated operational voltage of 690 V AC, a rated insulation voltage of 1000 V AC and an AC-23A utilisation category, providing a robust solution for main switching and isolation duties in high-current electrical installations.
