£1,399.49
The ABB 1SDA100424R1 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 ABB SACE Tmax XT5S series, this three-pole circuit breaker combines high breaking performance with an advanced electronic protection unit, making it ideal for demanding electrical installations.
The breaker is equipped with the Ekip Dip LS/I electronic trip unit, offering adjustable long-time overload protection together with selective and instantaneous short-circuit protection. These functions enable precise protection coordination, helping improve system reliability while reducing unnecessary downtime.
With a rated uninterrupted current of 400 A, a rated operating voltage of up to 690 V AC and the higher XT5S interruption rating, the ABB 1SDA100424R1 is well suited to industrial switchboards, distribution panels, motor control centres and OEM machinery requiring enhanced fault interruption capability.
Moulded case circuit breakers such as the ABB XT5S 400 continuously monitor electrical circuits and disconnect the supply whenever overload or short-circuit conditions occur. This helps protect cables, machinery and electrical equipment while improving installation safety and reducing downtime.
The integrated Ekip Dip LS/I electronic trip unit provides adjustable protection settings, allowing engineers to coordinate upstream and downstream protective devices for improved system selectivity and operational continuity.
