UBZ-304 Numeric electric motor protection device is designed for protection of asynchronous LT motors having power of 2.5 to 315 kW (5A – 630A), with use of external standard current transformers having output current of 5 amperes (secondary), works in power mains with isolated neural or with solidly grounded neutral terminals. The device provides continuous monitoring of the mains voltage parameters and RMS phase/line currents of the three-phase electric equipment of 380V-415V 50Hz, as well as for the motor insulation resistance test. More than 90 parameters can be programmed/customized depending on application & usage with variable trip delay and auto-reset delays. Four line full function backlit LCD display provides all information and eases programming from front panel. Built In RS-232 & RS-485 Modbus communication for DCS/ SCADA integration, realtime monitoring, programming and remote control. Device comes with free PC software for real-time monitoring & programming.

Three phase LT motor protection, 2.5kW – 315kW (4HP – 500HP) programmable, Built-in RS232 & RS485 Modbus/ASCII communication, Programmable Relay – SPDT (1NO+1NC) 16A & Power Relay – DPDT (2NO+2NC) 8A
