1SDA054445R1 ABB Control Industrial Automation Components

ABB 1SDA054445R1 is a Moulded Case Circuit Breaker (MCCB) designed for use in various applications requiring ring-lug or bar connections. It features a rated current of 400A and a rated voltage of 750Vdc, with a control voltage of 690Vac. The MCCB has a net height of 8 kV and a net width accommodating 3-poles (3P3d), offering thermal protection for overload scenarios and magnetic protection for short-circuit conditions. The protection functions are rated at 1000 V, utilizing technology with the identifier 888614401532. It has dimensions of H205mm x W140mm x D103.5mm and operates within a network frequency designated as T5H complete breakers. The visual position indicator is marked as 39121616, and the supply voltage supports up to 7000 operations under load, with electrical durability extending to 20000 operations for analog outputs. The diameter for a 1-pole configuration is 19.5 W, and the power dissipation/losses are noted as 400 AT. The trip current rating stands at 400 AF, employing thermal-magnetic technology that is adjustable within the TMA series, though it lacks a display. The short circuit current breaking capacity (Icn) includes over-current adjustments ranging from 0.7 to 1 x In (280A to 400A) and short-circuit pickup current adjustments from 5 to 10 x In (2000A to 4000A), with an impedance of 5kA (1s).
