ABB Ekip Hi‑Touch LSIG 6MT0344174715030 Electronic Trip Unit Product Description

Overview

ABB Ekip Hi‑Touch LSIG 6MT0344174715030 is a high‑end electronic protection and metering trip unit for ABB SACE Tmax XT / Emax 2 circuit breakers. This ABB Ekip Hi‑Touch LSIG trip unit integrates LCD touch display, full set of LSIG protection, power measurement, power quality analysis and communication functions. Ekip Hi‑Touch LSIG is the model series, 6MT0344174715030 is the unique serial/config part number tied to rated current, firmware and feature license. It is widely used for low‑voltage distribution cabinet upgrade and spare‑part replacement of ABB Tmax XT and Emax 2 breakers.

Features

ABB Ekip Hi‑Touch LSIG supports full LSIG protection: long‑time overload, short‑time delay short‑circuit, instantaneous short‑circuit and earth fault protection. This ABB trip unit provides true RMS measurement of three‑phase voltage, current, active/reactive power, power factor, frequency and energy, with up to 63rd harmonic analysis and waveform capture. Ekip Hi‑Touch LSIG has a built‑in touch screen for local parameter setting, trend viewing and fault code checking. It supports Modbus TCP, Modbus RTU and Ekip communication protocol for SCADA and energy management platform connection. Additional protection packages such as voltage, frequency, reverse power and ROCOF can be activated via ABB Ability Marketplace license. It integrates self‑diagnosis, event log and trip waveform recording for fast troubleshooting.

Principle

ABB Ekip Hi‑Touch LSIG obtains current signals from the breaker built‑in CTs and voltage signals from external PTs. The internal metering and protection chip continuously compares measured values with configured protection thresholds. Overload triggers long‑time delayed trip; selective short‑circuit triggers short‑time delay trip; heavy short‑circuit triggers instantaneous trip; earth leakage over-limit triggers earth fault trip. It records timestamps, current waveforms and alarm codes. Local touch screen or Ekip Connect software can modify protection curves, read measurements and export fault records.

Applications

ABB Ekip Hi‑Touch LSIG is deployed in factory main distribution rooms, commercial buildings, data centre low‑voltage rooms, water treatment and petrochemical auxiliary power systems. This ABB trip unit is fitted on Tmax XT and Emax 2 breakers for transformer feeders, mains incoming and important load selective protection. Ekip Hi‑Touch LSIG fits breaker overhaul and spare replacement of ABB high‑end metering protection trip units.

Installation & Maintenance Notes

Follow official ABB Ekip Touch hardware manual during installation of Ekip Hi‑Touch LSIG. Confirm CT polarity and wiring sequence. Back up all protection curves, communication settings and licenses before replacement. After replacement, perform protection test and communication verification. Check auxiliary power and communication cable shielding regularly. Confirm the full part number 6MT0344174715030, rated current and breaker frame compatibility before spare‑part swap‑out.
