SE-B3
Protection functions and properties:
• Temperature monitoring
– The device locks out immediately when the preset motor winding temperature, discharge gas temperature or
oil temperature is exceeded.
• Single phase failure monitoring
• Replaces the SE-B1 and SE-B2 models with a supply voltage of 110 .. 240 V.
The SE-B2 remains available as an evaluation unit for oil flow monitoring.
• The previous models are fully exchangeable, with the same functionality and terminal assignment. Dimensions
and their integration into the control are also identical.
• Does not comply with EN/UL 60730 ➨ SE-B5 .
