ETU electronic trip unit, LSI-function, fine setting of parameters via display,

3-pole

• overload protection L:
  Ir = 64 A up to 160 A
  tR = 3 s up to 20 s
• Short-time delayed short-circuit protection S :
  Can be switched on/off and switchable from standard to I2t characteristic for better selectivity adjustment to downstream fuses,
  Reduction of cable cross-sections by optimum adjustment of the trip unit
  Isd (standard) = 192 A up to 2400 A
  Isd (I2t) = 192 A up to 2400 A
  tsd = 0 up to 500 ms
• Instantaneous short-circuit protection I:
  Ii = 480 A up to 2400 A

LED display for

• operational readiness of the breaker
• overtemperature alarm
• overload alarm at 0.9 x Ir and 1.05 x Ir
• Monitoring of communication between breaker and breaker data server

• protection against phase unbalance (settable unbalance ratio 5 up to 40%)

• Remote parameterization via communication and/or connected notebook
• Recording of phase currents
• Status of the breaker and energy buffer is recorded and displayed/signaled

Diverse communication options e.g. for

• parameterization within the scope of commissioning
• 1/4-hourly average values  for energy management
• Status messages/alarm indications& reason for trippig for plant monitoring

via

• Integrated Ethernet interface integrated in the communication module 10/100Mbit (Modbus TCP)
• Optional slots for
  expansion module SWITCHED ETHERNET PROFINET
  expansion module PROFIBUS DP V1
  expansion module RS485 Modbus RTU

Optional expansion by residual current devices for fault currents from 30 mA to 10 A (type A) or 30 A (type AC).
