I'm building a pump controller with my raspberry.


The idea has been taken from http://www.techjava.de/topics/2014/01/basement-drainage-pump-control-and-iot/


I have an automatic pump like http://www.valco.eu/sitemanager/file/r_4_installation-dernajo-liqua_1.jpg

I control the current and if it is out from specific range for a specific time I switch off the pump and send an alarm.

To control the current i use amp clamp but to switch off I need a more powerful relay  ThinkerForge  has a Dual Relay Bricklet but support not enough Amp (when pump self start ) drained by pump.


There is a Solid State Relay AC 380V/25A but I'm worry about Temp.


Is the possibility to use a relay like a SONGLE SLA 05 S L C.  Or something to substitute to the solded relay or the PCB has to be rebuild.
