Description of ZYM1LE Series Molded Case Leakage Circuit Breaker
The ZYM1LE Series Molded Case Leakage Circuit Breaker is a cutting-edge protective device independently developed by our company, integrating globally advanced design concepts and precision manufacturing technologies. Beyond the basic protection capabilities of traditional molded case circuit breakers, it adds professional residual current protection, forming a comprehensive safety barrier for electrical systems. This breaker is designed to address potential electrical hazards in daily operation, effectively filling the gap that overcurrent protection alone cannot cover—specifically guarding against long-term ground faults that may trigger fire risks, while ensuring stable operation of power circuits and equipment.
Parameter of ZYM1LE Series Molded Case Leakage Circuit Breaker
The ZYM1LE Series comes with stable and industry-compliant technical parameters to meet diverse application needs. Its rated insulation voltage reaches 800V, matching the voltage requirements of most low-voltage power systems. In terms of short-circuit breaking capacity, it is classified into two grades based on the rated ultimate short-circuit breaking capacity (Icu): M-type (medium-high breaking capacity) and H-type (high breaking capacity), allowing flexible selection according to the actual short-circuit risk of the application scenario. It supports a rated working current range of up to 630A, compatible with both small and medium-sized power circuits and light industrial motor circuits.
Feature of ZYM1LE Series Molded Case Leakage Circuit Breaker
The ZYM1LE Series boasts multiple competitive features that enhance its practicality and reliability. It has a compact footprint, occupying less space in electrical cabinets, which is particularly beneficial for scenarios with limited installation space. It delivers excellent breaking performance, with short arcing distance during short-circuit breaking, reducing the risk of electrical arcing damage to surrounding components. It also has strong vibration resistance, maintaining stable operation even in slightly vibrating environments such as industrial workshops with mechanical equipment. In terms of installation, it supports both vertical and horizontal mounting, adapting to different cabinet layout requirements. It is important to note that reverse wiring is not allowed; the power supply lines must be connected to terminals 1, 3, 5, and the load lines to terminals 2, 4, 6 to ensure normal protection function.
Application of ZYM1LE Series Molded Case Leakage Circuit Breaker
Tailored for AC 50Hz power systems with a rated working voltage of 400V and rated working current up to 630A, the ZYM1LE Series is widely applicable in various industrial, commercial and civil scenarios. It is ideal for non-frequent circuit switching and non-frequent motor starting tasks, making it suitable for power distribution systems in factories, shopping malls, residential buildings, office buildings, and small and medium-sized industrial workshops. Additionally, it is perfectly suited for equipment protection in power supply lines, electrical control panels, and motor control circuits, providing reliable safeguard for both power infrastructure and electrical devices in harsh or regular operating environments.
