| Benefits | A25 trip units offer advanced electronic protection and control for power distribution and feeder protection. A25 trip unit's circuits and microprocessors measure electrical values against preset or user-selected parameters. These parameters include overload, short circuit, current unbalance, and over/under voltage/frequency. When required, A residual ground current transformer provides sensing for ground fault protection when needed. A25 trip units offer standard LS, LSI and LSIG circuit protection functions. A25 trip units can provide advanced functions like Digital Metering, Arc Flash Reduction Mode, and Zone Selective Interlocking. They also offer communication capabilities for transmitting metered values and status to monitoring or control networks. A25 trip units consist of 3 models, each offering different control, display, diagnostics, and communication options. Each model can be ordered in one of 3 protection configurations. Protection Configurations: - LI - Long Time-delay Overload, Instantaneous Short Circuit. - LSI - Long Time-delay Overload, Short Time-delay Short Circuit, Instantaneous Short Circuit - LSIG - Long Time-delay Overload, Short Time-delay Short Circuit, Instantaneous Short Circuit, Equipment Ground Fault Features: - Microprocessor based true RMS sensing - Discrete rotary trip setting dials - Cause of trip LEDs - Unit status LED - Making / breaking protection (MCR) - Ready-To-Close Indicator - Available zone selective interlocking - Available arc flash reduction mode - Available RS-485 communications - USB port for power & communication - Service short circuit protection (HSISC) |
