Specifications: Parameter Specification Product Range MasterPact MTZ (Accessories - Trip Units) Device Type Digital Micrologic Electronic Trip Unit (Series 2.3) Rated Breaker Frame For use with MasterPact MTZ circuit breakers. Protection Functions • Long-Time Delay (Ir) • Short-Time Delay (Isd) • Instantaneous (Ii) • Ground Fault (Ig) with adjustable sensitivity (0.5 x In). Measurement & Display • Front LCD Display • Measures: Phase Currents (IL1, IL2, IL3), Neutral Current (In), Ground Fault Current (Ig), Voltage, Frequency, Power (kW, kVA), Energy (kWh). Current Sensor Rating 1.5 A (This is a key specification. It must be matched with external Current Transformers (CTs) that have a secondary output of 1.5 A). Ground Fault Sensitivity 0.5 d (Adjustable, referring to the ground fault pickup setting as a multiple of the sensor rating). Communication Capability Embedded Communication Ports: • 1 x Ethernet (Modbus TCP) • 1 x USB (for local configuration via EcoStruxure Power Commission software) Note: For other protocols (EtherNet/IP, PROFIBUS, etc.), an additional communication module (IFE/MIF) must be added. Settings & Configuration Via front-panel buttons and display, or via USB/Software. Standards & Approvals IEC 60947-2, UL 489, CSA, CE, etc.
