Standard connection options
The breakers are equipped with front access terminals designed to allow the user to quickly and easily connect standard conductors. The MML169 frame has box clamps suited for one or two cable cores or busbars while the MCL169, MCA639 and MCE1609 frame sizes are configured to allow for easy busbar connection.

Configurable connection options
A wide range of alternatives are available in kit form with rear and angular connectors, spreaders, customised ring terminal connectors and extenders. Single and multiple box clamps can be directly fitted to the breaker terminals or in combination with extenders and spreaders. This flexibility allows the user to adapt MC9 circuit breakers to almost all standard connection configurations while at the same time allowing for the use of over-dimensioned and/or multiple conductors.

Terminal shields
Each breaker can be fitted with tamper resistant, short or long, terminal shields that allow a IP30 finishing of the product. Backplates and phase separators complete this line and consistently enable the user to connect the products safely. Additionally, frame specific accessories as the IPXXB terminal cover for the MML and the widened and elongated terminal shield for the MCA639 frame are available.
