Why Choose the ABB 1SDA073916R1 Emax 2 E4.2 Fixed Part?
The ABB 1SDA073916R1 is a fixed part for a withdrawable ABB SACE Emax 2 E4.2 air circuit breaker, providing the stationary chassis and main-circuit connection interface for the compatible withdrawable moving part. This four-pole version has a rated uninterrupted current of 4000 A and is designed for demanding low-voltage power distribution and switchgear applications.
As part of the advanced ABB SACE Emax 2 range, the 1SDA073916R1 is configured for E4.2 withdrawable circuit breakers, including the V performance version. The withdrawable architecture allows the compatible breaker moving part to be racked into and out of its fixed chassis, supporting inspection, maintenance and replacement while the fixed part remains integrated with the switchgear.
The fixed part features four poles, 100% neutral-pole current capacity and rear horizontal terminals. With a rated uninterrupted current of 4000 A, rated insulation voltage of 1000 V AC and rated impulse withstand voltage of 12 kV, it provides a robust connection platform for high-current Emax 2 switchgear installations.

Withdrawable Circuit-Breaker Integration for High-Current Switchgear
A withdrawable air circuit-breaker installation separates the breaker assembly into a stationary fixed part and a removable moving part. The fixed part remains mechanically and electrically integrated with the switchgear, providing the main power connection and racking interface while the compatible breaker can be moved between its operating positions and withdrawn for maintenance.
The ABB 1SDA073916R1 provides this stationary interface for a four-pole Emax 2 E4.2 rated at 4000 A. Its rear horizontal bolted terminals and robust chassis construction make it suitable for high-current switchboards where reliable power distribution, serviceability and efficient breaker maintenance are important.
Typical Applications
- High-current low-voltage main distribution switchboards.
- ABB Emax 2 E4.2 withdrawable air circuit-breaker installations.
- Industrial power distribution systems.
- Commercial and infrastructure electrical distribution.
- Critical-power switchgear requiring withdrawable circuit breakers.
- OEM switchboard and power distribution panel construction.
