Explanation: This is a regulation in Spain: The maximum power (hence current) a home is allowed to absorb from the grid is contracted for, and the means to control that you do not get beyond that at any moment is an mcb (miniature circuit breaker), whose trip characteristic in overcurrent is quite tightly tailored to the abovesaid maximum allowed current.
(And, as a plus, it also protects against short-circuits).
There fore, ICP-M stands for "Interruptor de Control de Potencia - Magnetotérmico", which translates as
"Power control switch -mcb"
Though there is a possible redundancy, or possible misunderstanding in putting together "switch" and "mcb", therefoer I woud translate as
"Power control mcb", or "mcb for power control".
