£1,351.85
The ABB 1SDA100489R1 is a premium 400 A moulded case circuit breaker (MCCB) designed to provide dependable overload and short-circuit protection for industrial and commercial low-voltage power distribution systems. As part of the advanced ABB SACE Tmax XT5H range, this three-pole circuit breaker combines high interruption performance with an advanced electronic protection unit for demanding electrical installations.
Fitted with the Ekip Dip LSI electronic trip unit, the breaker provides adjustable long-time overload, short-time delay and instantaneous short-circuit protection. These protection functions enable accurate coordination with downstream protective devices, improving system selectivity and operational continuity.
With a rated uninterrupted current of 400 A, a rated operating voltage of up to 690 V AC and a high breaking capacity, the ABB 1SDA100489R1 is suitable for industrial switchboards, distribution panels, motor control centres and OEM machinery where reliable circuit protection is essential.
The ABB XT5H series moulded case circuit breakers continuously monitor electrical circuits and disconnect the supply whenever overload or short-circuit conditions occur. This helps protect valuable equipment, minimise downtime and improve the safety of industrial electrical installations.
The integrated Ekip Dip LSI trip unit allows engineers to fine-tune protection settings, making the breaker suitable for complex power distribution systems requiring selective coordination and dependable fault isolation.
