1SDA100361R1 ABB XT5N 400 Ekip Dip LSIG 320 A 3-Pole Circuit Breaker

Why Choose the ABB 1SDA100361R1 XT5N 400 Ekip Dip LSIG Circuit Breaker?

The ABB 1SDA100361R1 is a SACE Tmax XT5N 400 moulded-case circuit breaker (MCCB) designed for dependable protection of low-voltage AC power distribution systems. This fixed, three-pole circuit breaker combines the XT5 platform with an Ekip Dip LSIG electronic trip unit rated at 320 A, providing comprehensive protection against overloads, short circuits and earth faults.

As part of the ABB SACE Tmax XT series, the XT5N combines compact construction with configurable solid-state 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 coordinated protection across a wide range of distribution systems.

The 1SDA100361R1 is supplied in a fixed, 3-pole configuration with front terminals. It uses the XT5 400 A frame with a 320 A Ekip Dip LSIG release, while the N interruption-performance level provides an ultimate short-circuit breaking capacity of 36 kA for demanding power-distribution applications.

Comprehensive LSIG Protection for Power Distribution

The ABB Ekip Dip LSIG release combines four essential electronic protection functions. Long-time protection responds to sustained overloads, short-time protection supports selective coordination during short-circuit conditions, instantaneous protection provides rapid interruption of severe faults, and the earth-fault function adds protection against ground-fault currents within the distribution system.

With its 320 A electronic release, 400 A XT5 frame, fixed three-pole construction and front terminals, the 1SDA100361R1 provides a robust protection solution for substantial low-voltage loads. Its 36 kA N-class interruption performance and configurable LSIG protection make it well suited to industrial switchboards, transformer-fed systems and other installations requiring coordinated electronic circuit protection.
