  • How many amperes does a relay protection device draw

    How many amperes does a relay protection device draw

    The coil in an SPST relay typically draws 150-200 mA of current with a coil resistance of about 60-80 ohms. You can test the relay using a multimeter. If the resistance is too high or shows an open circuit, it might mean the coil is damaged. A relay rated to switch 10 amps of AC voltage may have a much lower amperage rating for DC voltage because DC arcs are more difficult to extinguish. 6 amps to energize it at pins 85 and 86 to power the device it is controlling. It states "15A 125VAC". Does that mean it will. The “NEMA Standard ICS 5-2017” standard applies to general-purpose mechanical, electro-mechanical, and solid-state devices that are principally used in industrial applications for control-circuit switching and the control of solenoids rated not more than 600 volts.
