Why Choose the ABB T4L250 PR222DS/P-LSIG In250 3p FFC Circuit Breaker?
The ABB T4L250 PR222DS/P-LSIG In250 3p FFC, order code 1SDA054512R1, is a high-voltage three-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax T range, designed for dependable protection of industrial AC electrical distribution systems. Built on the T4L 250 frame, it combines fixed installation with an advanced PR222DS/P-LSIG electronic trip unit for comprehensive overload, short-circuit and earth-fault protection.
Designed for specialised high-voltage applications, this circuit breaker has a rated operational voltage of 1000 V AC and a rated current of 250 A. The T4L performance level provides a rated ultimate short-circuit breaking capacity of 12 kA at 1000 V AC, supporting reliable fault interruption in industrial switchboards and high-voltage AC distribution installations.
The breaker is supplied in a fixed three-pole configuration with front terminals for copper cables. Its PR222DS/P-LSIG solid-state release provides LSIG protection functions, combining long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection for enhanced coordination and protection of electrical installations.
