Why Choose the ABB E4.2V/MS 3200 3p F HR Switch-Disconnector?
The ABB E4.2V/MS 3200 3p F HR, order code 1SDA073420R1, is a high-performance three-pole fixed air switch-disconnector from the ABB SACE Emax 2 range. Rated at 3200 A, it is engineered for dependable switching and isolation in demanding low-voltage power distribution systems where substantial continuous-current capability and very high short-time withstand performance are required.
The E4.2V/MS is a switch-disconnector rather than an automatic circuit breaker equipped with an electronic protection release. Its V-performance construction provides a rated short-time withstand current of 100 kA for 1 s and 75 kA for 3 s, enabling the device to withstand severe prospective fault currents while appropriately coordinated protective devices perform automatic fault interruption.
This version combines a fixed three-pole configuration with rear flat horizontal terminals for integration into high-current switchboards. With a rated operational voltage of 690 V AC, rated insulation voltage of 1000 V AC and rated impulse withstand voltage of 12 kV, the E4.2V/MS 3200 provides robust electrical isolation for industrial, infrastructure and critical power distribution applications.
