3kw heaters installation

[Wardy83]

Hi, I’ve been asked to install 5x 3kw ceiling heaters in a room for a salon.
I just want to check how you would install them?
I’m thinking a radial in 4mm2 cable (singles in conduit), from cu to thermostat, to contactor to heaters, 13amp f/spur at each heater?
Customer wants them all to come on at same time hence the contactor.

Advice/ thoughts Welcomed.

Cheers

Take the control circuit through a slide lock fuse within the contactor housing, been done that way since Jesus played in goal for Bethlehem

Alternatively, could I just mount an MCB on the DIN rail next to the contactor for the control circuit?

Why not if there is ample space
