Saide DC MCCB 320A 3p DC MCCB with high capacity moulded case circuit breaker

SDM3 series photovoltaic special DC molded case circuit breaker is suitable for DC grid circuit with rated voltage up to DC1200V and rated current of 250A. DC circuit breaker has overload long delay protection, short circuit instantaneous protection function , used to distribute electric energy and protect circuit and the power supply equipment is protected from the danger of overload, short circuit, etc.

The operating mechanism of the DC circuit breaker has the functions of quick closing and fast reading segmentation, compact structure, small size and convenient use.

Here are some key features and specifications of the SAIDE 320A 3p DC MCCB with high capacity:

Maximum Rated Voltage: The MCCB is designed to handle a maximum rated voltage of AC 1140V. This means it can safely operate within electrical systems with voltages up to 1140 volts.

Maximum Current: The MCCB has a maximum current rating of 400A, which indicates the maximum current it can carry without tripping or causing damage.

Breaking Capacity: In the case of AC voltage of 800V, the MCCB has a maximum breaking capacity of 50kA. This ensures reliable short-circuit protection for the system by effectively interrupting high fault currents.

AC High Voltage MCC Series: Saide Electric also offers a 400A AC high voltage MCC (Molded Case Circuit) series. This particular series has a maximum rated voltage of AC 1500V and a maximum current of 800A.

DC Voltage Application: The 320A 3p DC MCCB with high capacity series is also suitable for DC voltage applications. In the case of DC voltage of 1500V, it has a maximum breaking capacity of 20kA, providing reliable short-circuit protection.
