4P 125-250A 400V AC MCCB

With a wide temperature range from -20 °C to + 70 °C, MCCB can adapt to different climate and environmental conditions, whether it is cold in the northern winter or hot in the southern summer, it can work normally. 4P 125-250A 400V AC MCCB with IEC 60947-2 standard, to ensure the quality and performance of the product in line with international standards. Through the effective monitoring and rapid response of overload, short circuit and other faults, effectively eliminate the hidden dangers of electricity safety in life, and ensure the safety of personnel and equipment.

The operating temperature range covers -20 ℃ to + 70℃, which can operate stably in extreme weather conditions. In a cold environment, the internal electrical components and mechanical structure will not be embrittlement or performance degradation due to low temperature; In a high temperature environment, it can also effectively heat dissipation, avoid failures caused by overheating, ensure the continuous and stable power supply of the power system, and reduce the impact of environmental temperature changes on electrical equipment.

The operation handle of the white plastic case circuit breaker is insulated plastic, and the operation force is accurate and moderate. The insulating material ensures safety, allowing the operator to safely perform the on off operation, efficient and safe.
