SE-B2
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 with a supply voltage of 24 V AC and 24 V DC.
• Is replaced by: SE-B3 with a supply voltage of 115 .. 230 V.
• 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 .
