NHP has introduced the DIN-T dc series miniature circuit breaker (MCB), specifically designed to protect dc circuits up to 250V dc single-pole or 440V dc for two-pole MCBs connected in series.
This makes the DIN-T dc series a truly universal product for ac and dc systems.
The performance of a circuit breaker varies greatly for ac and dc systems. Generally speaking, dc faults are more difficult to interrupt as extinguishing the arc formed by the contacts opening presents more challenges, especially the higher the applied voltage.
It is worth noting that the standard DIN-T MCB range is also acceptable on voltages up to 48V dc per pole. For higher voltages specify DIN-T dc series MCBs.
