The CARLO GAVAZZI DWB02CM4810A is a high-precision general purpose relay designed for monitoring active power in three-phase balanced systems. Manufactured in Italy, this relay provides reliable measurement and control for industrial applications involving asynchronous motors and symmetrical loads.
TRMS active power relays suitable for 3-phase applications
Measures if active power is within set limits, with adjustable upper and lower levels
Capable of measuring its own power supply
Measurement ranges include 5A, 10A, and MI current transformers
Power ON delay adjustable from 1 to 30 seconds via knob
Programmable latching or inhibit functions to maintain alarm status or prevent relay operation during maintenance
Automatic and manual start/stop system control
Output: 8 A SPDT relay, normally energized or normally de-energized selectable
Mountable on DIN-rail (DIN/EN 50 022) or as a plug-in module (PWB02)
Housing options include 45 mm Euronorm housing or 36 mm plug-in module
LED indicators for relay status, alarm, and power supply
Key Features
Adjustable upper and lower power setpoints from 10% to 110% of nominal load
Operation Modes include latch, inhibit, start/stop, with adjustable delay and hysteresis
Wiring and Mounting
Designed for DIN-rail mounting or as a plug-in module, suitable for various industrial control panels. Wiring diagrams are available for different configurations including start/stop and latch functions.
Additional Information
