- Description
This is the withdrawable moving part of ABB's 1SDA072962R1, a SACE Emax 2 E2.2B 1600 Ekip Dip LSI four-pole air circuit breaker - a matching fixed part (cradle) is needed to complete the installation. It carries a 42 kA breaking capacity (Icu) at 400 V AC and a 1600 A uninterrupted current rating, with the fourth pole switching the neutral in four-wire 690 V AC systems.

Selection Notes
This four-pole WMP moving part pairs with a separate fixed cradle, unlike the fixed F HR version - pick it when retrofitting a four-pole withdrawable Emax 2 installation already in service. It carries the same 1600 A rating and 42 kA Icu as the three-pole moving part, with the LSI release's short-time delay enabling coordinated tripping ahead of an instantaneous trip. The fourth pole handles neutral switching for four-wire systems.
