Is there a DC thermal relay?
Our synchronous motor DC zero excitation undercurrent protection is used in this model. You can specifically check the next, you need the JL14 overcurrent relay model.
JLl4 series AC and DC current relay (hereinafter referred to as relay), suitable for AC 50Hz voltage 380V and below, DC voltage 220V and below the control circuit as overcurrent or under current protection purposes.
AC thermal relays can also be used as DC thermal relays (like AC-DC thermal relays). There are DC overcurrent and undercurrent relay, you can choose DC overcurrent relay to be a DC thermal relay oh.
Protection of DC motor, no thermal relay, with a DC current relay on it.
