ABB 1SDA073725R1 M E2.2...E6.2 220-250 VAC/DC

This ABB 1SDA073725R1 is an air circuit breaker configured with the adjustment designation E2.2...E6.2 and a 220–250 VAC/DC control rating. As an air circuit breaker, this unit is built to provide adjustable overcurrent protection and switching in low-voltage electrical installations where a defined trip range and a 220–250 VAC/DC operating/control supply are required. The model ID and adjustment range identify the exact configuration of this ABB air circuit breaker for procurement and panel integration.

In low-voltage power distribution, an ACB circuit breaker of this specification is used where selectable trip settings and a 220–250 VAC/DC control interface are needed for protective and operational coordination. This low voltage air circuit breaker form factor is commonly integrated into switchgear and distribution panels to protect feeders, bus sections, and critical loads while allowing precise setting with the E2.2...E6.2 adjustment. Specifying this ABB air circuit breaker ensures the selected trip range and control-voltage compatibility are matched to the system requirements.
