DC MCCB SM8-400HPV 1500V

DC MCCB SM8-400HPV 1500V

• The circuit breaker has a beautiful appearance, compact size, and high breaking capacity.

• The product has non-polarity for current, providing reliable protection for both forward and reverse connections.

• It can operate reliably within a temperature range of -40°C to +70°C without derating at +50°C.

• Zero arc exposure: Equipped with an arc extinguishing cover and three layers of free metal partition plates, preventing secondary faults caused by arc spraying during breaking

• It has a single-phase DC1500V grounding breaking capacity of 10kA.
