ABB 1SDA073910R1 E2.2 W FP Iu=2000 4p HR HR

This ABB air circuit breaker is a factory-identified industrial air circuit breaker supplied under the SKU 1SDA073910R1. It is presented with the model/series identifier E2.2 and the marking W FP, and the product title specifies an Iu=2000 rating and four poles (4p). As an ACB circuit breaker, this unit is a low voltage air circuit breaker designed for use where a factory-specified, high-capacity trip solution is required within switchgear assemblies.

In low-voltage power distribution, an ABB air circuit breaker like this is used as the primary protective device for incoming feeders and main bus sections in electrical distribution boards and switchgear. Industrial control rooms, commercial distribution panels, and main switchboards commonly specify an ACB circuit breaker when a four-pole configuration and the higher continuous current designation shown in the title (Iu=2000) are required. Specified identifiers in the title (E2.2, W FP, HR HR) define the exact factory configuration and trip option for integrators and switchgear builders who require matched components.

• Brand: ABB
• SKU / Catalog Number: 1SDA073910R1
• Product Series: E2.2
• Number of poles: 4p
• Rated current (In): Iu=2000
