Temperature Relays and MINIKA®
Quick guide PTC thermistor relay MSR820V
1 Application and short description
ZIEHL PTC thermistor tripping devices protect motors, transformers, machines and systems against thermal overload.
Together with ZIEHL PTC thermistor temperature sensors type MINIKA®, response values between 60°C and 180°C can be
realized.
The MSR820V monitors up to 8 PTC thermistor circuits. The individual circuits can be activated or deactivated during
operation.
