Why Choose the ABB 1SDA054073R1 T4L 250 Moulded Case Circuit Breaker?
The ABB 1SDA054073R1, designated T4L 250 PR221DS-I In=160 3p F F, is a fixed three-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax T4 range, designed for reliable protection and control of low-voltage power distribution circuits in commercial and industrial installations.
This T4L circuit breaker combines a robust 250 A frame with a 160 A PR221DS-I solid-state electronic trip unit. The electronic protection system provides overload and instantaneous short-circuit protection, helping safeguard cables, switchgear and connected electrical equipment against damaging overcurrent conditions.
With a three-pole fixed configuration, front terminals and a rated operational voltage up to 690 V AC, the 1SDA054073R1 is suited to fixed installation in industrial switchboards and distribution panels. The T4L version provides a high short-circuit breaking capability of 120 kA at 415 V AC, making it suitable for distribution systems where substantial prospective fault currents may occur.
