Why Choose the ABB 1SDA100175R1 XT4N 250 Circuit Breaker?
The ABB 1SDA100175R1 is a SACE Tmax XT4N 250 moulded case circuit breaker designed for dependable protection of low-voltage AC power distribution systems. Part of the ABB SACE Tmax XT range, this fixed three-pole breaker combines the compact XT4 frame with an Ekip Dip LSI electronic trip unit for configurable overload and short-circuit protection.
Rated at 250 A, the breaker incorporates LSI protection functions covering long-time overload, short-time short-circuit and instantaneous short-circuit protection. The long-time protection setting covers 100–250 A, while the short-time and instantaneous thresholds provide adjustable protection for coordinating the breaker with upstream and downstream protective devices.
The XT4N designation identifies the normal breaking-capacity version of the XT4 platform, while the 3p F F configuration specifies a three-pole, fixed circuit breaker with front terminals. With a rated operational voltage of up to 690 V AC and an ultimate short-circuit breaking capacity of 36 kA at 415 V AC, the 1SDA100175R1 is well suited to industrial, commercial and infrastructure distribution systems.
