MOLDED CASE CIRCUIT BREAKER

"The CMTM3E series electronic molded case circuit breaker is suitable for low-voltage power grids with AC 50Hz/60Hz, a rated insulation voltage of 800V, a rated current up to 800A, and a rated operating voltage of AC 380V (400V). Equipped with an intelligent trip unit, this circuit breaker adds rated current selection and provides three-protection functions: overload long-time delay, short-circuit short-time delay, and short-circuit instantaneous protection

UNIVERSAL CIRCUIT BREAKER

1. The CMTW1 series universal circuit breakers are suitable for AC distribution networks operating at 50 Hz, with rated voltages of AC 400 V and AC 690 V, and rated currents ranging from 400 A to 6300 A. They are used to distribute electrical power and protect circuits and power‑supply equipment against faults such as overloads, undervoltage, short circuits, and single‑phase ground faults. 2. These circuit breakers feature high breaking capacity and zero arc flash, along with a variety of intelligent protection functions. They provide selective protection, operate with high precision, minimize unnecessary outages, and enhance the reliability of power supply.

PHOTOVOLTAIC RECLOSING DEVICE

The CMTM5L series residual current‑operated circuit breaker (hereinafter referred to as the automatic recloser) is a new product developed by our company in recent years. It is an integrated, multifunctional circuit breaker with adjustable overcurrent settings. This product incorporates all the protection functions of an intelligent molded‑case circuit breaker—long‑time inverse‑time overload protection, short‑time inverse‑time short‑circuit protection, short‑time definite‑time short‑circuit protection, and instantaneous short‑circuit protection—while also providing additional protective features such as residual current delay, overvoltage delay, and undervoltage delay.
