CMTW1 Series Intelligent Universal Air Circuit Breaker (ACB)

The CMTW1 Series Intelligent Universal Air Circuit Breaker (ACB) is designed for use in AC 50/60Hz power distribution networks with a rated operating voltage of 400V/690V and rated operating current ranging from 200A to 6300A. This breaker plays a critical role in distributing electrical power and protecting circuits and power equipment from hazards such as overload, under-voltage, short circuit, and grounding faults.

Equipped with a precise selective protection system and multifunctional intelligent controller, the CMTW1 series is especially suited for distribution networks where high reliability and minimizing downtime are essential. The breaker provides complete protection functions and can be configured with a leakage current transformer for leakage protection.

Key Features:

• Smart Control: The 2H and 3H models feature communication interfaces for integration with field buses, enabling remote monitoring, adjustment, control, and data transmission.

• Enhanced Protection: Includes protection against electromagnetic interference in new energy PV systems, environmental disturbances, and leakage protection.

• Automatic Resetting: Features under-voltage reclosing protection for improved system uptime.

• Compliance: Meets the mandatory national CCC certification and complies with international standards, including IEC60947-1, IEC60947-2, and GB/T14048.2.

The CMTW1 Series ACB is ideal for high-demand distribution networks where continuous power supply and reliable protection are critical. Additionally, for motors with rated current up to 1000A, it provides overload, short-circuit, under-voltage, and grounding fault protection, suitable for infrequent motor starting under normal conditions.
