NHP has released the Sprecher + Schuh CET5 motor protection relay. It provides motor protection with power monitoring and communication capabilities. The accurate thermal modelling of CET5 results in maximum motor output without risk to the installation. It is therefore suitable for low and medium voltage motors.
CET5 provides several option cards to fulfill the requirements of most applications. This includes a voltage card for power and voltage monitoring, Modbus and DeviceNet cards for communication and an RTD scanner module for the temperature monitoring of up to 12 RTDs.
CET 5 can be retrofitted to current applications. Its modular pluggable options and accessories, CWE 4 current converter connection and its networkability for integration into automation systems, further enhance its adaptability.
