IMP
Intelligent Motor Protection Relay
• Ground fault protection for both zero current/residual current
• Support rated current 0.12~100A without external current transformer
• Definite/inverse time selection and diverse protection factors
• Basic application of ground fault/instance protection
• Separation of the display part with the use of cables
• MODBUS communication and 4~20mA DC output
