ABB 1SDA073711R1 M E1.2 220-250 VAC/DC

This listing describes an ABB air circuit breaker identified by SKU 1SDA073711R1. The unit is presented with the E1.2 trip designation and a control/operational voltage range of 220–250 VAC/DC. As an air circuit breaker, this device is intended to provide overcurrent protection and switching in low-voltage electrical installations where an ACB circuit breaker form factor and trip functionality are required.

The ABB air circuit breaker is used in low-voltage power distribution assemblies and switchgear panels that require a dedicated trip unit and a 220–250 VAC/DC control interface. In switchgear, an industrial air circuit breaker such as this is selected when a configurable trip characteristic (E1.2) and the stated control voltage are required to integrate with protection and control circuitry. This description refers specifically to the ABB 1SDA073711R1 ACB circuit breaker and does not infer additional ratings or features beyond those shown.
