Alors il semble que le produit reçu ne correspond pas à la photo.\r\nLes cosses de commande basse intensité ne sont pas placées au dessus comme sur la photo. Moi ça ne va pas me gêner, mais il conviendrait de réactualiser les photos par rapport aux nouveaux produits.\r\n

Not navy
After a season without function, when dismantling the magnets and holder were found to be badly corroded, screws not made of VA, very rusty
Not suitable for marine use, switching load for Tigres with 1500W too low, contacts already badly damaged
At almost three times the price of a truck relay, it's really weak!

Technical question

Can this control box be mounted upside down, or do the solenoids require the 4 connection terminals are facing upwards? I ask because when I have the control box in my hand and gently shake it up and down, I hear a clunk noise inside, suggesting a part within the control box is moving when no power is applied. Is this normal to hear a rattle inside the box when it is shaken? Thanks

I learned from Lofrans that this box cannot be mounted upside down - the connection terminals must be facing upwards. When we had it mounted facing downwards, operating the windlass would trip the breaker the second time the control was actuated. First time usually worked. Once we altered our mount bracket so the control box could be remounted with connection terminals facing upwards, the box works fine.
