ABB 1SDA100429R1 SACE Tmax XT5S 630 A three-pole fixed moulded case circuit breaker with front terminals and an Ekip Dip LSI electronic trip unit for industrial power distribution.
£2,582.21
The ABB 1SDA100429R1 is a premium 630 A moulded case circuit breaker (MCCB) engineered to provide dependable overload and short-circuit protection for industrial and commercial low-voltage power distribution systems. Part of the advanced ABB SACE Tmax XT5S range, this three-pole circuit breaker combines a compact fixed design with an advanced electronic protection unit for demanding electrical installations.
The breaker is equipped with the Ekip Dip LSI electronic trip unit, offering adjustable long-time overload, short-time delay and instantaneous short-circuit protection. These settings allow engineers to coordinate protection across the electrical installation, improving system selectivity and operational reliability.
With a rated uninterrupted current of 630 A, a rated operational voltage of up to 690 V AC and a 50 kA breaking capacity at 380 to 440 V AC, the ABB 1SDA100429R1 is ideally suited to industrial switchboards, motor control centres, commercial distribution panels and OEM machinery requiring high-performance circuit protection.
Moulded case circuit breakers such as the ABB XT5S 630 continuously monitor electrical circuits and disconnect the supply whenever overload or short-circuit conditions occur. This protects valuable equipment, minimises downtime and improves the safety of industrial and commercial electrical installations.
The advanced Ekip Dip LSI trip unit enables accurate protection settings for long-time, short-time and instantaneous faults, helping engineers achieve selective coordination across complex power distribution systems.
