This video highlights how to wire elevator shunt trip using an addressable system sensor type relay, while also supervising for power loss with an MR-101 and a system sensor style monitor module.
Make sure you don't burn the building down... The relay module you are using is only 26mA You should use 2 MR-101/C... 1 to monitor the power and 1 to activate the shunt... The AC power should go though the MR-101 which is capable of handling 7Amps...
Thank you for your concern, but doing it this way will not burn the building down. The relay module we are using is not only rated for 26mA. I am not sure where you received that information, but the manufacturers documentation clearly states that it is rated for .5A @ 120VAC. Using 2 MR-101 relays is indeed a way that you could go about this, however it is unnecessary. We are not shunting the 230VAC that is powering the elevator so we do not need the 7A rating of the MR-101 contact. We are merely using the addressable relay to activate a shunt trip coil inside the breaker which is a much lower current application. The shunt trip breaker will then disconnect the 230VAC. This method puts all the load on that breaker and not on our relay. the only load switching through our relay is that of the small electro-magnet inside of the shunt trip breaker assembly commonly called a "shunt trip coil."
Thank you for pointing this out. From a functional standpoint, dry contacts such as these are not polarity specific so they can be wired either way, but for the purpose of a training video I should be more careful to match the diagrams and the real things so as not to confuse anyone.

Next time can you explain which wires you use to wire it example 14 2 and 18 2

Straight to comments after I seen the diagram
Are you saying that you use the MR-101 to supervise the circuit??
yes, the MR-101 is there to supervise the power.
You have your common and NO wires reversed when you wired it vs what the diagram shows.

Followed what u said didnt work
Which part are you having issues with? Did the power not cut off to the elevator or are you having issues monitoring for power?
You have to run the nuteral to the shunt trip also
