The holding Voltage/current to keep a relay on is normally lower then the voltage needed to turn it on. Keeping the higher voltage/current across the relay just heats the relay.

WebbTo prevent possible non-release of a relay armature caused by retained magnetism in the core, a residual air gap is left between the armature and the core when the relay is operated. The requisite residual gap is ensured by means of a fixed stud or adjustable screw with lock-nut and is generally within the limits of 4 to 20 mils.
