Why Choose the ABB 1SDA054109R1 T4V250 PR221DS-I Circuit Breaker?
The ABB 1SDA054109R1 is a SACE Tmax T4V250 moulded case circuit breaker designed for switching and short-circuit protection in demanding low-voltage power distribution systems. ABB identifies this configuration as T4V250PR221DS-IIn=1604pFF, combining the T4V250 platform with a rated current of 160 A and four-pole construction.
The breaker is equipped with an ABB PR221DS-I electronic trip unit. Its instantaneous I protection function provides rapid response to severe short-circuit currents, making the breaker suitable for applications where instantaneous fault protection is required and other protection functions are coordinated separately.
Configured as a fixed breaker with front terminals, the 1SDA054109R1 is suited to permanent installation in compatible switchboards, distribution panels and OEM assemblies. Its four-pole format, T4V performance level and 160 A rating provide a robust solution for professional industrial and commercial power distribution.
