Solid State Overload Relays - RW_E Series
The RW_E is meant to assure increased reliability for protection of low voltage three-phase electric motors in sinusoidal 50/60 Hz networks where reliability, low power dissipation and ease maintenance management are mandatory.
Description
With direct mounting on the contactors or on an individual base, the RW_E electronic overload relays provide protection for electric motors up to 840 A.
Main Characteristics
- Incorporated protections: overload, phase loss and phase imbalance
- Available in the three-pole version
- Adjustable tripping classes: 10, 20 and 30
- Direct coupling to the CWB and CWM contactors without accessories
- Accessory to enable mounting on DIN rail 35mm (EN 50022) or tightened with screws
Energy Saving
Due to its conception and design, the electronic circuits of the RW_E relays present very low energy consumption and smaller thermal dissipation (below 0.38 W up to 25 A); therefore, they contribute to reducing the demand for ventilation in the electrical panel.
Built-in protections
- Overload
- Phase loss
- Phase imbalance
