Description of ZYM1LC Series Residual Current Protection Circuit Breaker
The ZYM1LC Series encompasses two specialized circuit breaker variants: Residual Current Protection Circuit Breakers (RCBOs) and External Molded Case Circuit Breakers for Electric Meters. Engineered to meet the rigorous requirements of modern power distribution systems, this series adheres to the GB/T14048.2 standard, ensuring exceptional quality, reliability, and compliance with national and industry safety norms. The RCBO variant is tailored for AC power grids, while the external molded case model is optimized for power information collection systems operated by State Grid and China Southern Power Grid. Together, these two types deliver comprehensive protection and intelligent control, addressing diverse electrical safety and management needs across residential, commercial, and industrial scenarios.
Parameter of ZYM1LC Series Residual Current Protection Circuit Breaker
The ZYM1LC Series features tailored parameters for its two variants, ensuring optimal performance in respective application scenarios. The Residual Current Protection Circuit Breaker operates at AC 50Hz, supports a rated current of up to 400A, and is compatible with rated working voltages of AC 380V/400V/415V, and adaptive three-phase four-wire grounded neutral systems. It integrates precise protection mechanisms, with response parameters calibrated to avoid false tripping while ensuring rapid activation during faults.
For the External Molded Case Circuit Breaker for Electric Meters, the rated working voltage ranges from 220V to 400V, and it adopts switch signal control, enabling seamless integration with prepayment electric meter systems for automated on-off operations. Both variants fully comply with the GB/T14048.2 standard, boasting excellent insulation performance, stable mechanical switching, and long service life to withstand frequent operation in complex power environments.
Application of ZYM1LC Series Residual Current Protection Circuit Breaker
The ZYM1LC Series caters to dual application scenarios, leveraging its two variants to cover power protection and intelligent metering control. The Residual Current Protection Circuit Breaker is widely used in AC 50Hz power distribution networks with a rated current of up to 400A and rated working voltages of AC 380V/400V/415V. It is particularly suitable for three-phase four-wire power supply and consumption systems with directly grounded neutral points, providing critical protection for circuits and electrical equipment, as well as safeguarding against ground faults and indirect personal contact hazards.
The External Molded Case Circuit Breaker for Electric Meters is specifically designed for power information collection systems of State Grid and China Southern Power Grid. It is controlled by prepayment electric meters to switch on or off based on the user’s power account status, making it ideal for residential communities, commercial buildings, industrial parks, and other scenarios requiring intelligent power management and prepayment control.
