CDM3-63F/4300A 20A Molded Case Circuit Breaker Introduction
Product Overview
The CDM3-63F/4300A 20A molded case circuit breaker is designed for low-voltage power distribution systems, suitable for AC 50Hz networks with rated operational voltage up to 400V. With 20A rated current and modular design concept, this device provides reliable circuit protection by promptly interrupting power supply during overload or short-circuit conditions. Its compact structure ensures efficient space utilization while maintaining stable performance.
Core Features
-
Reliable Breaking Capacity
Incorporating thermal-magnetic trip mechanism and optimized arc extinguishing system, the breaker maintains consistent protection capability at 4300A breaking capacity. The bimetal strip and electromagnetic coil work in coordination to achieve precise overload time-delay protection and instantaneous short-circuit protection.
-
Advanced Material Technology
High-strength engineering plastic enclosure provides excellent insulation and mechanical durability. Copper alloy contacts with surface treatment technology minimize contact resistance and energy loss, extending service life.
-
User-Friendly Operation
Ergonomic handle with clear ON/OFF position indicator requires ≤50N·m operating force. Transparent viewing window allows visual status confirmation. Supports both panel mounting and DIN rail installation.
-
Comprehensive Safety Protection
Fast-acting mechanism triggers within 10ms for short-circuit protection. Contact system utilizes arc acceleration structure to suppress arc generation. Fully enclosed design achieves IP40 protection level against dust intrusion and accidental contact.
Application Scenarios
• Industrial plants: Production line distribution cabinets
• Building automation: Lighting control circuits
• Infrastructure: Public utility power networks
• Commercial facilities: Data center PDU systems
Installation & Maintenance
Suitable for vertical/horizontal mounting. Recommended terminal tightening torque: 6-8N·m. Annual contact inspection suggested for oxide removal. Always ensure complete power isolation before operation.
