Datasheets

Electronic overload relays have been designed primarily to protect electric motors and associated electrical circuits.

These devices operate on the principle of monitoring the current in a motor starter circuit which, when the current exceeds a pre set condition, or there is a loss of current in any phase, the device will initiate a trip circuit which in turn causes the power to the starter (contactor) to be disconnected thus making the circuit safe.

Features:

• Low power consumption
• Great accuracy
• Full reliability
• Phase unbalance protection
• Interchangeable with thermal overload relay
• Multiple trip class selection
• Manual / Auto reset

Main characteristics:

• Setting range from 0.1 up to 150A
• Self powered
• Thermal memory
• Phase loss protection
• Phase unbalance protection
• Direct fitting to contactors Series CL
• Interchangeable with thermal overload relay
• Multiple ttrip class selection
• Manual / Auto reset
• Increased flexibility, less order codes, less stock
• Tripp class: 5 - 10 - 20 - 30

Manual

Motor protection and motor control with pre-programmed motor typicals. Status/Maintenance/Management information through communications.

In addition the system offers the possibility to obtain a readout of the status of the motors and gear apparatus as well as maintenance information. In addition it offers the user user-friendly options to manage settings and configurations.

New features of the system:

• Communications redundancy due to availability of the Modbus RTU and Profibus DP communications lines
• User-friendly touchscreen windows offer motor control directly from the panel or combined operation of up to 32 motors by means of a clear colour touchscreen
• Predefined control logic with which the desired drive configuration can be selected easily and quickly
• A logbook of analogue values and events with real-time timestamps
• 24V DC or 100 to 240 V AC power supply

The system is ATEX and SIL-certified, which makes it possible to be utilised in the most demanding environments, such as petrochemical installations, oil rigs and power plants.
