Looking for contactor that fits in single box

[simpson93]

Afternoon all,

As title suggests I’m not sure if such a product exists but I’m looking for a 20amp contactor that is mounted into a single box/patress

Reason being another sparks has wired 2 ufh mats 1800w each onto a single spur (14-16amp)

 

[telectrix]

why not swap the back box for a dual outlet box and fit 2 x SFCUs.

Yep, that would work fine but I would prefer not to put 16amps+ threw the thermostat

 

[telectrix]

why not. it's rated for it? and if you have "proper" voltage of 240V, it's 15A. beaRING IN MIND THAT IT'S INTERMITTENT AS THE STAT. SWITCHES OFF WHEN THE SET TEMP. HAS BEEN ACHIEVED.and the bloody caps lock right next to the "A". stupid layout. should have been put by the Q or the Z.

 

[simpson93]

I would agree with you but it’s never good to be running it at 100% 24/7


There is also the potential although unlikely to go upto 16.36amp

Thermostat is currently tripping rcbo if trying to run both mats

 

[telectrix]

what's the RCBO rating?

No wonder 'ring in mind' jumped out at me.....

Good luck with your search please keep us informed.

If you do end up needing one a relay will be a lot quieter than a clunky contactor. These are compact and good quality, with screw mounting lugs.

Or solder tags.

Quite a good price, too.

If you're driving a heating load, what about a SSR?
RS Pro 25A SSR 90-240Vac control
or similar would seem ok and are quite compact to be tucked into a box?

NB: I'm not up on any UK regs that would cover or prohibit the use of such industrial gear in a home. You would definitely want upstream isolation for maintenance, as SSR can fail closed if shorted.
