1SDA100515R1 ABB XT5H 400 Ekip Dip LIG 320 A 3-Pole Circuit Breaker

Why Choose the ABB XT5H 400 Ekip Dip LIG 1SDA100515R1 Circuit Breaker?

The ABB XT5H 400 Ekip Dip LIG 1SDA100515R1 is a high-performance 320 A moulded case circuit breaker (MCCB) designed for dependable protection and switching in demanding low-voltage electrical distribution systems. Part of the ABB SACE Tmax XT series, this three-pole breaker combines the XT5 400 frame with an Ekip Dip LIG solid-state electronic trip unit and H-class short-circuit performance.

The Ekip Dip LIG release provides adjustable long-time overload, instantaneous short-circuit and ground-fault protection functions. Its electronic protection architecture makes the breaker suitable for protecting energy distribution systems, cables, generators and other installation circuits where accurate protection settings and reliable fault interruption are required.

With a rated current of 320 A, a three-pole fixed configuration with front terminals and an ultimate short-circuit breaking capacity of 70 kA at 415 V AC, the 1SDA100515R1 is engineered for high-demand distribution applications. Its long-time protection is adjustable from 128–320 A, instantaneous protection from 320–3200 A, and the ground-fault function from 0.2–1 × In.
