Carlo Gavazzi Monitoring Relay Load Guard 3-Phase Plug-In PWA01CM485A

Carlo Gavazzi Monitoring Relay 3-Phase Load Guard, Plug-In, SPDT, Supply: 380-480VAC.

DWA01 and PWA01 are precise over or under cos ϕ monitoring relays. The relays monitor their own power supply voltage and the current of a balanced 3-phase system. For current measure direct connection, 5A standard current transformers and MICT can be used. The LED's indicate the state of the alarm and the output relay. 

General Characteristics

• Cos ϕ monitoring relays.
• Measuring if power factor is within set limits.
• Measure their own power supply (voltage) and current for balanced systems.
• Measuring ranges for current: 5A and MI current transformers range.
• Power ON delay 1, 2 or 6 s selectable.
• Knob adjustable level on absolute scale.
• Output: 8 A SPDT relay Normally Energized.
• For mounting on DIN-rail in accordance with DIN/EN 50 022 (DWA01) or plug-in module (PWA01).
• 22.5 mm Euronorm housing (DWA01) or 36 mm plug-in module (PWA01).
• LED indication for power supply and output ON.
