SEPL 4P 32A 1000V DC Miniature Circuit Breaker (MCB)

SEPL 4P 32A DC Miniature Circuit Breaker is designed for protection and isolation of photovoltaic DC circuits against overload and short-circuit conditions. The four-pole configuration supports DC systems with operating voltage up to 1000V DC, making it suitable for high-voltage solar PV strings, DC distribution boxes and photovoltaic protection systems. The breaker has a rated current of 32A and provides a rated short-circuit breaking capacity of 6kA. Its instantaneous trip characteristic operates within the specified 8–12 × rated current range. The device can also be used for infrequent manual switching and isolation of DC circuits during maintenance and system servicing. DIN-rail construction allows convenient integration into solar DC distribution and combiner boxes.
