ABB Phase Monitoring Relay, 1, 3 Phase, DPDT, DIN Rail

Mainly used for asynchronous motors (cage rotors) on a single-phase or 3-phase network with significantly changing loads
The internal electrical isolation of the supply and measuring circuits means it can be used in networks that are separated
Monitors the load status of inductive users
Window monitoring cos φ min. and cos φ max. in one device
2 changeovers
Suppression time for the starting time can be adjusted from 0.3 → 30 s
Single-phase or 3-phase monitoring
3 LEDs for function monitoring

Load monitor

Using the load monitor allows all machines that are driven by electric motors to be monitored securely. This load monitor can be used for early detection of damage to the bearings or gear, blockage or idling of the screw-conveyors or conveyor belts, as well as V-belt failures or filter blockages, in order to prevent more severe damage or machine failures.
The Telehaase load monitor does not require additional sensors or transducers. It can be used without a current transformer from 230 to 6930 W. Even when operating a frequency inverter, monitoring tasks are completed easily. With all load monitors, start-up bridging and a switching delay can be calibrated.
