Why Choose the ABB 1SDA100355R1 Tmax XT5N Circuit Breaker?
The ABB 1SDA100355R1 is a high-performance 630 A moulded case circuit breaker (MCCB) designed to protect industrial and commercial low-voltage power distribution systems against overloads and short circuits. Part of the advanced ABB SACE Tmax XT range, this three-pole circuit breaker combines compact construction, dependable interruption performance and an electronic protection release.
The circuit breaker is equipped with an Ekip Dip LS/I solid-state trip unit, providing adjustable long-time overload protection together with selective and instantaneous short-circuit protection. This electronic release supports precise protection settings, helping engineers coordinate the breaker with cables, downstream equipment and other protective devices.
With a rated uninterrupted current of 630 A, an operating voltage of up to 690 V AC and a breaking capacity of 36 kA at 380–415 V AC, the ABB XT5N 630 is suitable for demanding switchboards, distribution panels and industrial power systems. Its fixed three-pole configuration and front terminals enable straightforward installation and cable access.
