Tumbles female magician, pointing to circuit breaker (4,6)

'magician pointing to circuit breaker' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'tumbles female' is the wordplay.
I cannot quite understand how this works, but
'female' could be 'witch' (witch is a kind of female) and 'witch' is found in the answer.
The remaining letters 'trips' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?
