Core Advantages:
Strong Breaking Capacity: 50kA ultimate breaking capacity, quickly interrupting short-circuit faults and protecting the safety of the power distribution system.
Three-Phase Compatibility: The 3340 structure is compatible with three-phase circuits, with clear wiring terminals (top input, bottom output).
Intuitive Status Indication: Clear "ON/OFF" switching indicators, with a red indicator light for fault warning.
Dual-Mode Protection: Thermal tripping for overload protection and magnetic tripping for rapid short-circuit protection, providing bidirectional protection for lines and equipment;
Maximum Durability: Silver alloy contacts + flame-retardant casing, supporting over ten thousand breaking operations for long-term stable operation;
Flexible Installation: Rail-mounted design compatible with standard electrical cabinets, supporting drawer/fixed installation, adapting to different power distribution layouts.
Applicable Scenarios: Factory power distribution cabinets, commercial building HVAC systems, elevator power circuits, and front-end protection for photovoltaic inverters.
Certification: Complies with international/domestic electrical safety standards such as IEC 60947-2 and GB 14048.2. CE certified.
The CHM1-400L/3340 provides reliable thermal-magnetic protection for three-phase power distribution systems with its 400A high current capacity and 50kA high breaking capacity, suitable for core circuits in industrial and commercial applications.
