Advanced Electronic LS/I Circuit Protection

The ABB EPX-XT4S-E1-1003 uses an Ekip Dip electronic trip unit to monitor electrical current and initiate protective tripping when overload or short-circuit conditions occur. Its LS/I protection functionality provides long-time overload protection alongside a selectable short-circuit protection mode. Short-time delayed protection can support coordination with downstream protective devices, while instantaneous protection provides rapid tripping for high-current faults.

The ABB SACE Tmax XT4S160 platform combines electronic protection technology with a robust mechanical switching system. Its three-pole construction provides coordinated protection for three-phase electrical circuits, while the 100 A current rating and 50 kA breaking capacity make it suitable for appropriately designed commercial and industrial distribution installations. The LS/I release provides flexibility when selecting protection characteristics to suit the electrical network and its coordination requirements.
