You really should use a contactor rated for DC. Arcing can potentially be a serious problem on DC circuit. With AC, the voltage drops to zero 100 or 120 times a second, tending to extinguish arcs, on DC the arc cam be maintained unless special provisions are made to extinguish it.

The 415 VAC contactor would still have to have a 15 A rating. The coil will probably have to be changed out with a suitable DC coil. DC circuits rarely have AC control voltages.

I fancy Bon Scott AC/DC.. Brian Johnson AC/DC i will take or pass away because of the fact after returned in Black..the riffs all sound too such as me for me to have any super liking for them. bq - I haven't any thought considering i'm no longer a musician My widespread AC/DC music is it is an prolonged thank you to the suitable (in case you Wanna Rock n' Roll)
