The Power Electronics PT433-8 phase monitor checks the voltage of a three-phase supply for the loss of one or more phases or the neutral. It protects asynchronous three-phase motors from supply irregularities by also monitoring phase imbalance, overvoltage and undervoltage.
- Power supply: 3 x 230 V AC / 50 Hz
- Imbalance monitoring: Adjustable, 5–25%
- Front-panel imbalance setting: 5–20% Vnom
- Relay outputs: One changeover contact, 10 A / 250 V AC, cat. AC1
- LED indicators: POWER ON and RELAY ON
- Connection base: Plug-in type, 8-pin
- Protection: Varistor against overvoltage and lightning
- Operating temperature: -20 to +50 °C
- Connection requirement: Neutral required
- Type
- Phase Monitor
