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.

Reliable Protection for Industrial Power Distribution
Moulded case circuit breakers such as the ABB XT5N 630 interrupt excessive current before it can damage cables, machinery or electrical distribution equipment. The electronic Ekip Dip LS/I release continuously monitors the circuit and operates the breaker when configured overload or short-circuit thresholds are exceeded.
The adjustable long-time, selective short-circuit and instantaneous protection functions support coordinated system design. This makes the ABB 1SDA100355R1 suitable for installations where reliable fault isolation, operational continuity and protection accuracy are essential.
