Product Description
About NS
Our NS series of MCCB has already provided ODM/OEM and other related services to many well-known demestic and foreign manufacturers.
"With professional heart, do professional thing" reflects our commitment to the pursuit of excellent quality.
In order to ensure each MCCB can meet the high standard requirement of performance and safety, every production workshop is equipped with long-delay, short delay, in stantaneous efficacy desk, withstanding voltage calibration desk, mechanical life test rack, intelligent tester and other testing equipment. We test rigorously for the product' tripping precision, sensitivity and reliability of mechanical operation, and the material of key accessories, so as to ensure every product can meet the customer's quality requirement.
In order to control costs and quality effectively, all accessories of the circuit breaker are designed, molded and put into continuous production on our own.
Our commitment to all customers is to offer the products with the best cost-performance ratio.
