From Lexicanum

Power Mauls, are Imperial power weapons most commonly used by the Adeptus Arbites^1-p34.

Effectively a baton surrounded by a power field, the Power Maul has a hidden subtlety: the power field setting can be extensively adjusted so that its discharge effect can vary from bashing a hole through a wall, or indeed armour plate, to delivering a sudden knock-out blow to an individual. This tactical depth-of-use makes it a valued tool of Imperial law enforcement.

Arbites shock troops employ the weapon in combination with the Suppression Shield.

Inquisitors and higher ranked individuals usually refer to them as Shock Mauls^2-p141, possibly referring to a slighter variant of the same weapon (they're known to speak of shock maul also when talking about the standard Arbites equipment).
