Product Introduction: Application: Thermal/thermal overload Brand: Tianshui 213 Model: JRS4-12316d Product Series: JRS4 Contact Form : One open and one closed current properties: AC Appearance: small
JRS4 series thermal overload relays are used in circuits with currents of 50Hz or 60Hz and rated voltages up to 660V for overload and phase failure protection of AC motors.
This relay has the same characteristics as the LR2-D series thermal relay and can be used interchangeably.
