Why Choose the ABB 1SDA054093R1 T4V 250 Moulded Case Circuit Breaker?
The ABB 1SDA054093R1, designated T4V 250 PR221DS-LS/I In=100 3p F F, is a high-performance moulded case circuit breaker (MCCB) designed for dependable protection of low-voltage AC power distribution systems. As part of the proven ABB SACE Tmax T4 series, it combines compact construction with electronic protection and very high short-circuit interruption capability for demanding commercial and industrial installations.
This circuit breaker uses the PR221DS-LS/I solid-state electronic trip unit with a rated current of 100 A. The release provides long-time overload, short-time and instantaneous short-circuit protection, allowing the breaker to protect cables, distribution equipment and downstream electrical loads against damaging overcurrent conditions.
The T4V 250 is supplied as a fixed three-pole circuit breaker with front terminals. Its V breaking-capacity class provides an ultimate short-circuit breaking capacity of up to 200 kA at 380/415 V AC, making the 1SDA054093R1 particularly suitable for installations with high prospective fault currents.
