Short Circuit Current Ratings (SCCR) of Three-Phase Monitor Relays

Does my Phase Monitor Relay require a Short Circuit Rating?

What happens when a time delay relay trigger is closed before voltage is applied?

Issue: I am using a time delay relay with a triggered function. My trigger switch will be closed before I apply voltage to the time delay relay. Will this work? Solution/Resolution: In a typical application with a triggered time delay relay, voltage is first applied to the timer, then the trigger is applied to begin the function. Some applications, however, require the trigger to be closed before voltage is applied. Most Macromatic time delay relays will recognize the trigger when applied prior to the application of voltage, however, some will not.

Using DPDT Cross-Wired Alternating Relays with HIGH-LOW Float Switches

Issue:

I have two float switches and two pumps in my application: a HIGH float switch to pump the water down and prevent an overflow of the tank, and a LOW float switch to turn the pump off and prevent the tank from being emptied & burning out the pump.
