It is a surge protector.

A common mode acting filter with a high, broad band attenuation ratio.
A ZNR varistor surge serves as the overvoltage suppression component.
The earthed capacitors are tested and approved as so-called
class Y noise suppression capacitors.

See page 7 of the document below.
