Q: What is the max frequency for a Kaizen Relay?
A: 225 Hz. 

Q: Are fuses needed with Kaizen Relays? 
A: We recommend fusing the input power only. Each output is thermally protected and will shut down the output in the case of an overload, including a complete short circuit!

Q: What current is considered a short circuit? 
A: Typically 135A, but it may be between 80-175A depending on supply voltage and temperature.
