Series Overview
Outstanding Features
- Convenience
- Accessory box packaging.
- Can be installed horizontally, vertically, or flat.
- Diversity
- Four neutral pole types: The neutral pole of the 4-pole circuit breaker can be with or without protection, and can be directly connected or disconnected.
- Temperature upload: Configured with the WD1 temperature upload module, it can communicatively upload and monitor the temperature of 4 main circuit connection points.
- Thermal-magnetic communication: Configured with the ZT3 status upload module, it enables remote status monitoring and open/close operations for thermal-magnetic circuit breakers.
- Earth leakage alarm without tripping: CM3L circuit breakers can feature earth leakage alarm without tripping, avoiding significant losses caused by power outages.
Installation and Usage Conditions
The circuit breaker is designed for normal service conditions as recommended by GB/T 14048.1:
- Ambient air temperature: Not exceeding +40°C with a 24-hour average not exceeding +35°C. The lower ambient air temperature limit is -5°C. Ambient air temperature refers to the air temperature surrounding the circuit breaker.
- Altitude: Not exceeding 2000m.
- Atmospheric conditions:
- Humidity: Relative humidity of the air not exceeding 50% at the maximum temperature of +40°C. Higher relative humidity is permissible at lower temperatures, e.g., 90% at +20°C. Special measures should be taken for occasional condensation due to temperature changes.
- Pollution Degree: 3.
- Transport and storage conditions: -25°C ~ +55°C (up to +70°C for short periods).
Use the circuit breaker under the following conditions when exceeding the standard specified service conditions:
- Ambient air temperature: The circuit breaker can operate in ambient temperatures from -25°C to +70°C, but derating is required above +40°C. For ambient temperatures as low as -40°C, low-temperature type products are recommended.
- Altitude: Derating is required for altitudes above 2000 meters.
- Atmospheric conditions:
- Humidity: If the standard recommended usage conditions are exceeded, take appropriate measures to meet the conditions.
- Atmospheric environment: Besides meeting Pollution Degree 3, it also satisfies the air micro-environment requirements for location class 3C2 as specified in GB/T 4798.3.
- Shock and vibration resistance: The circuit breaker can be used in locations meeting the mechanical conditions class 3M4 of GB/T 4798.3. It has passed the GB/T 2423.10 test requirements and can withstand mechanical vibration with a frequency of 2Hz~13.2Hz and displacement of ±1mm, and a frequency of 13.2Hz~100Hz with acceleration of ±0.7g. The circuit breaker has passed the GB/T 2423.5 test requirements and can withstand peak acceleration of 150m/s² and pulse duration of 11ms in both positive and negative directions.
- Installation: The circuit breaker can be installed horizontally (sideways), vertically (upright), or flat.
- Transport and storage conditions: Ambient air temperature -25°C ~ +70°C, relative humidity ≤50% (moisture-proof packaging should be used for storage in tropical humid regions).
- Electromagnetic compatibility (EMC): The circuit breaker has passed the EMC test items specified in Appendix F and J of GB/T 14048.2.
