Description
Chint NM10-600/330-600A Miniature Molded Case Circuit Breaker 600A 480V 3-pole
The NM10 Series Molded Case Circuit Breaker is primarily designed for use in power distribution networks with AC 50Hz frequency, a rated operating voltage of up to 380V, and a rated current of up to 600A, where infrequent operation is required. Its function is to distribute electrical energy and to protect circuits and power supply equipment against damage caused by faults such as overload, short circuit, and undervoltage. Circuit breakers rated at 250A and below can also serve the dual purpose of providing infrequent starting control for electric motors, as well as protection against overload, short circuit, and undervoltage conditions.
A derivative of this series—the transparent-case circuit breaker—features a cover constructed from a novel, high-temperature-resistant, and high-strength polycarbonate material. This design allows for a visual determination of the contact status (open or closed) and is widely utilized in temporary power supply installations at construction sites.
Compliant Standards: GB/T 14048.2, IEC 60947-2.
