QxN DC Miniature Circuit Breakers (MCBs)

Description

This is a two-pole (2P) circuit breaker designed specifically for DC circuits. It provides essential protection against overload and short circuits in DC systems. The DC marking and the dedicated schematic symbol indicate its use in DC applications, where arc suppression is critical. The C125 likely refers to a 125A rating with a C-type tripping curve (moderate time delay). The BD-100Z series name is the manufacturer’s model designation.
