Branch Circuit Breakers and Supplementary Circuit Breakers: Branch Circuit Breakers are UL 489 listed and can be used to protect multiple devices like in a control cabinet. They have a much more stringent testing requirements to insure safety for protection of multiple circuits. Supplementary Circuit Breakers can be UL 489 listed or UL 1077 recognized and are only to be used on individual devices and usually have protection upstream with a branch circuit breaker. Branch breakers can be used on individual circuits in place of a supplementary breaker. Supplementary breaks CAN NOT be used for multiple circuits like a branch breaker is designed to do.

Miniature circuit breakers (MCB) are compact circuit breakers with low current ratings and fixed trip settings used to switch and protect the lowest common distribution voltage in an electrical system. MCBs are available as complete units, or as plug-in units with bases.

Miniature circuit breakers may be simple breakers without a UL listing, or supplementary circuit breakers (UL 489 listed, UL 1077 recognized, or UL 2367 recognized to protect single devices), or branch circuit breakers (UL 489 listed to protect single or multiple devices).

MCBs have two tripping mechanisms – the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection. Miniature circuit breakers have current ratings below 100 Amperes, classified by the current range at which they trip instantly. These are some of the standard breaker overcurrent protection ratings:

  • Type A – Trips at under 2 times the rated current
  • Type Z – Trips at 2.4 to 3.6 times the rated current
  • Type B – Trips at 3 to 5 times the rated current, suitable for resistive or slightly inductive loads.
  • Type C – Trips at 5 to 10 times the rated current, suitable for moderate inductive loads.
  • Type D – Trips at 10 to 20 times the rated current, suitable for loads with a high inductive component.
