Looking for a replacement relay
I would avoid using the unapproved (for safety) Chinese piece of 'stuff' unless you have absolutely no other choice. 

It's usually a hindrance when you hide your location and ask for sources, by the way. 

Digikey (ships most places, but more cheaply to the USA and Canada) has the Schrack RM205730 for less than $20, for example. It's rated 230VAC coil and 16A contacts, and carries these safety agency markings: 



Meaning it has been tested to (and passed) safety agency standards for Canada, the USA and Germany. 

I have seen similar Chinese product marked with fake approval markings and dangerously defective, by the way. 

I suggest you do a parametric search at a distributor such as Digikey or MSC (US industrial wholesaler) or McMaster (USA) and find something that fits the same mounting holes, has the same width of spade terminals, and has at least as good ratings on the contacts. You can check the datasheet against your sample part.
