ABB 1SDA071781R1 E4.2S 3200 Ekip Dip LI 4p F HR

The ABB 1SDA071781R1 is an ABB air circuit breaker configured with the Ekip Dip LI trip assembly as indicated in the product designation. As an air circuit breaker (ACB circuit breaker), this unit is designed to provide overcurrent protection, fault isolation and switching in low-voltage distribution systems. The product title identifies the breaker configuration and trip electronics that define how the device senses and clears faults.

This low voltage air circuit breaker is intended for installation in switchgear and panel-mounted applications where a robust industrial air circuit breaker is required to manage distribution and protection duties. ACBs of this type are selected in switchgear for their ability to handle repeated switching operations, integrate with protection and metering electronics, and provide coordinated selective tripping with downstream devices. The ABB air circuit breaker designation in the model name identifies it as part of ABB’s protected breaker lineup used in commercial and industrial distribution networks.
