Product Description

ABB 1SDA054337R1 T5S400 FF PR222-LSI 400A Molded Case Circuit Breaker is engineered for advanced electrical protection in industrial, commercial, and critical power distribution systems. Its robust 3-pole design manages high currents up to 400A, making it suitable for main switchboards, branch circuits, and protection of high-load machinery.

The circuit breaker features a high breaking capacity of 85kA, providing reliable management of short-circuit events and minimizing risk of electrical damage. With fixed mounting and solid-state release PR222 LSI technology, users benefit from precise protection settings for overload, short circuit, and ground faults, supporting system stability and asset safety.

Operating voltages up to 690V AC allow flexible implementation across a range of industrial and commercial applications, including manufacturing plants, data centers, and infrastructure. The front terminal arrangement simplifies both installation and maintenance, reducing downtime and enabling safe access during system upgrades.

The lever actuator ensures easy reset after tripping, while its compact dimensions - 205mm height, 140mm width, 103.5mm depth - fit efficiently within modern switchgear panels. Compliance with CE, IEC, and RoHS standards confirms suitability for regulated environments and global export requirements.

Fixed mounting style increases mechanical stability and minimizes installation errors. Solid-state tripping mechanism responds rapidly to diverse system faults. Electrical durability rated at 60 cycles per hour under demanding conditions.

Rated impulse withstand voltage of 8 kV provides added safety for transient events. Short-circuit performance level S for robust protection in critical applications.

Industrial use cases include electrical distribution, machine protection, panel boards, facility infrastructure, and retrofitting legacy systems to modern safety standards. The ABB Tmax series is recognized globally for reliability and high performance in circuit protection.
