Miniature circuit breakers

Overview

Medray procures miniature circuit breakers for maintenance, replacement and project requirements. Provide the model or reference, quantity and operating conditions so the required configuration can be matched and sourced across available suppliers. Miniature circuit breakers interrupt abnormal current conditions and provide a manual switching point for protected circuits. The correct selection depends on the circuit voltage, prospective fault current, number of poles and trip characteristic. Supplementary protectors and branch-circuit breakers serve different installation roles; the applicable device standard must be checked for the actual part. Accessories, busbars and enclosure arrangements also require matching to the selected product family. Technical details to confirm: Rated current and trip curve; AC/DC circuit voltage; Breaking capacity at that voltage; Pole count; Branch or supplementary protection role.
