Why Choose the ABB 1SDA054072R1 T4L 250 Moulded Case Circuit Breaker?
The ABB 1SDA054072R1 is a SACE Tmax T4L 250 moulded case circuit breaker (MCCB) configured with a PR221DS-I electronic trip unit. ABB identifies this model as T4L 250 PR221DS-I IN=100 3P F, combining the T4L 250 breaker frame with a rated current of 100 A.
This circuit breaker uses a 3-pole configuration and fixed execution for integration into compatible low-voltage distribution equipment. The PR221DS-I electronic trip unit provides overload (L) and instantaneous short-circuit (I) protection functions for the connected circuit.
As part of ABB's established SACE Tmax range, the 1SDA054072R1 is designed for circuit protection and switching in industrial, commercial and infrastructure power-distribution systems where a 100 A, three-pole fixed MCCB with electronic protection is required.
