Basic Features

• Motor protection for small to medium-sized motors (100 KW to 2 MW).
• Certification for use in explosive environments (EN 60079-14 or Verband der Elektrotechnik, Elektronik und Informationstechnik 0165, Part 1, ATEX)
• Motor protection functions: Startup time monitoring, thermal overload protection for stator and rotor, restart inhibit, unbalanced-load protection, and load-jam protection 
• Stator and bearing temperature monitoring via temperature sensors with optional temperature inputs or with external resistance temperature detectors (RTD) unit
• Sensitive ground-fault protection (non-directional and directional) to detect stator ground faults 
• Directional and non-directional overcurrent protection (short-circuit protection) with additional functions 
• Uses pulse detection method to detect transient ground faults
• Protects from overvoltage and undervoltage
• Arc protection
• Configurable power protection (active or reactive)
• Control, synchrocheck and switchgear interlocking protection
• 2 optional pluggable communication modules, usable for different and redundant protocols (IEC 61850-8-1, IEC 60870-5-103, IEC 60870-5-104, Modbus TCP, DNP3 serial and TCP, and PROFINET I/O)
• Reliable data transmission via PRP and HSR redundancy protocols
• Extensive cybersecurity functionality (e.g. as role-based access control (RBAC), protocolling security-related events, signed firmware or authenticated network access IEEE 802.1X)
• Provides simple, quick and secure access to the device data via a standard Web browser to display all information, diagnostic data, vector diagrams, single-line diagrams, and device display pages
• Captures operational measured variables and protection function measured values for the evaluation of the systems to support commissioning and analyze faults
• Phasor Measurement Unit (PMU) for synchrophasor measured values and IEEE C37.118 protocol
• Enables powerful fault recording (buffer for a max. record time of 80 sec. at 8 kHz or 320 sec. at 2 kHz)
