The ABB 1SDA054510R1 is a specialist SACE Tmax T4L moulded case circuit breaker (MCCB) designed for demanding AC power distribution applications operating at up to 1,000 V AC. This three-pole fixed circuit breaker combines a 250 A rated current with ABB's PR221DS-I electronic trip unit.
The PR221DS-I electronic release provides electronic circuit protection for high-current distribution systems, offering a robust alternative to conventional thermomagnetic protection. The T4L 250 frame is specifically configured for elevated-voltage applications where dependable interruption of short-circuit currents is required.
For this T4L configuration, ABB specifies an ultimate short-circuit breaking capacity of 12 kA at 1,000 V AC. Fixed mounting and front terminals for copper cables make the breaker suitable for permanent installation in specialist industrial switchboards, distribution assemblies and other high-voltage AC systems.
The ABB SACE Tmax T4 range includes specialist configurations engineered for AC systems operating at voltages above conventional low-voltage distribution levels. The 1SDA054510R1 combines a 250 A current rating with the PR221DS-I electronic release, providing electronic protection for substantial three-phase circuits.
Its 12 kA ultimate breaking capacity at 1,000 V AC makes this T4L variant suitable for applications requiring circuit protection at elevated AC voltages. Fixed installation and front copper-cable terminals further support integration into purpose-built industrial switchboards, power conversion equipment and specialist distribution assemblies.
