Introducción:
- CNTN Electric molded case circuit breakers feature an insulation voltage of 800V. Except for model ZMM1‑63 rated at 400V, other models suit AC circuits up to 690V/50Hz with rated current from 63A to 800A, designed for infrequent switching of motor circuits.
- This series of molded-case circuit breakers integrates overload, short-circuit, and undervoltage protection functions, effectively safeguarding power distribution lines and electrical equipment while preventing equipment damage caused by various electrical faults.
- The circuit breakers manufactured by CNTN Electric feature robust short-circuit breaking capabilities, rapid arc-extinguishing speeds, and outstanding safety performance; providing users with reliable protection, they represent an ideal choice for power distribution equipment.
- The 1-pole MCCB is constructed from highly flame-retardant materials, offering efficient arc suppression as well as protection against dust, moisture, and electric shock. It can be installed directly within cabinets or outdoor enclosures, thereby eliminating the risk of accidental contact with live components.
- This Molded Case Circuit Breaker (MCCB) offers versatile and flexible installation options, supporting fixed, plug-in, and withdrawable configurations. Furthermore, it accommodates both vertical and horizontal mounting orientations, thereby meeting the diverse requirements of various power distribution layouts.
- Nuestro MCCB es adecuado para circuitos trifásicos de cuatro hilos, y también se puede utilizar para circuitos trifásicos de tres hilos y circuitos trifásicos de dos hilos.
- CNTN Electric not only manufactures 1 Pole MCCB circuit breakers in AC types, but also produces Disyuntores de caja moldeada de CC.
- CNTN Electric no sólo fabrica MCCB con cubiertas blancas de baquelita, sino que también produce MCCBs con cubiertas grises y negras de plástico.
