1SDA100191R1 ABB XT4N 160 Ekip Dip LSIG 40 A 4-Pole Circuit Breaker

Why Choose the ABB 1SDA100191R1 XT4N 160 Ekip Dip LSIG Circuit Breaker?

The ABB 1SDA100191R1 is a SACE Tmax XT4N moulded-case circuit breaker (MCCB) designed for comprehensive protection of low-voltage AC power distribution systems. This fixed, four-pole circuit breaker combines the compact XT4 platform with an Ekip Dip LSIG electronic trip unit rated at 40 A, providing protection against overloads, short circuits and earth faults.

As part of the ABB SACE Tmax XT series, the XT4N combines compact construction with microprocessor-based electronic protection for industrial, commercial and infrastructure applications. The Ekip Dip LSIG release provides long-time overload, short-time selective short-circuit, instantaneous short-circuit and earth-fault protection, enabling effective coordination of feeders, cables and connected electrical equipment.

The 1SDA100191R1 is supplied in a fixed, 4-pole configuration with front terminals. Its XT4N platform provides 36 kA short-circuit breaking capacity at 380–415 V AC, while the 40 A electronic release provides an instantaneous protection setting range of approximately 40–400 A, making the breaker suitable for lower-current distribution circuits requiring the performance and flexibility of the XT4 platform.
