FAQ

What is the primary difference between a DC circuit breaker like this and a standard AC breaker?

A DC circuit breaker is specifically designed to extinguish a DC arc, which is more difficult to interrupt than an AC arc because DC current is constant and doesn’t pass through zero. The C60H-DC has a specialized arc chute and mechanism for safe DC current interruption.

Can this A9N61521 breaker be used in a solar PV system?

Yes, this breaker is well-suited for solar PV applications, particularly for protecting DC strings or circuits from inverters and battery banks, provided the system’s voltage and current are within the breaker’s specified ratings.

What does the ‘C’ in the ‘C 6A’ rating signify?

The ‘C’ indicates the tripping curve of the breaker. A C-curve breaker is designed to trip at 5 to 10 times its rated current (6A in this case). It is a general-purpose curve suitable for resistive and inductive loads with low inrush currents, like lighting and control circuits.
