Default 7 day timer and Inductance current

I have a 7 day timer, with a max load of 13A at 240V.
However reading the instructions its states there is an inductance
current of 3A. What does this mean ?

If the load isn't resistive like a heater element, then the permitted
load is reduced.

Inductive loads such as the motors used in fridges or washing machines
can quite easily generate sparks when the power is switched off that in
an etreme case can weld the contacts together or damage them over time
so that they no longer make a low resistance connection. The problem can
be minimised by bridging the contacts with a capacitor, but then you get
problems with the permanent leakage current into the load, with the
safety problems that can cause.
