A connection module for a circuit breaker, the connection module being attachable to a main housing of the circuit breaker on a terminal side from which contact straps extend, the connection module comprising:

• a plurality of terminal compartments, each bounded by a first side partition, a second side partition, a rear wall, and a terminal compartment bottom, wherein:
• each rear wall includes an opening for one of the contact straps to extend into a corresponding one of the plurality of terminal compartments when the connection module is attached to the main housing;
• the plurality of terminal compartments are provided with lateral guide elements for box terminals to contact the contact straps, said lateral guide elements being formed in each of the first partition and the second partition;
• and
• the plurality of terminal compartments are provided with bottom-side guide elements for threaded plates to be inserted below the contact straps;
• a removable cover, removably coupled to a front of the connection module and bounding a front of each of the plurality of terminal compartments, wherein the removable cover is provided with a fastener access opening at each of the plurality of terminal compartments;
• and
• a plurality of receptacles, each originating at a corresponding terminal compartment bottom and extending away from a corresponding terminal compartment, each receptacle configured to extend coaxially with a through-hole of a corresponding contact strap, and each receptacle being closed at an opposite end that includes a breakaway wall portion for breaking away to receive a terminal sleeve for coupling to the corresponding contact strap.
