Electrical profile
To power the electromagnet with enough strength , it needs at
least 800mA current. The resistance of the electromagnet
inside SHCB01 is about 5 ohms at 15
℃
. A 5V power with at
least 5 watt capacity will be enough to power this simulated
circuit breaker to pop out. However, please keep in mind that
the resistance of the coil inside the electromagnet rises with
temperature. And because of the low resistance of the
electromagnet, please also mind the resistance of wire/cable
used to connect SHCB01. Higher the power voltage if needed.
