- Adjustable Settings: Adjustable trip settings for customized protection coordination.
- Visual Indicators: Trip indicator for rapid fault identification.
Application Scenarios
- Power Distribution: Main and feeder protection in industrial panels.
- Motor Protection: Protecting large motor circuits from overloads.
- Equipment Protection: Safeguarding transformers and switchgear.
Performance Parameters
- Interrupting Capacity: High interrupting rating for severe fault conditions.
- Trip Curve: Standard thermal-magnetic trip characteristic.
Material Composition
- Housing: High-strength, flame-retardant thermoplastic.
- Contacts: Silver-tungsten alloy for superior arc resistance.
Structural Characteristics
- Design: Compact molded case design.
- Terminals: Line and load terminals with torque markings.
Working Principle
Under normal conditions, current flows through the breaker contacts. During an overload, a bimetallic strip heats and bends to trip the mechanism. During a short circuit, a magnetic solenoid instantly trips the breaker to interrupt the fault current.
Installation Requirements
- Torque terminals to manufacturer specifications to prevent hot spots.
- Ensure proper phase rotation and polarity.
Usage Precautions
- Never operate a tripped breaker without investigating the root cause.
- Perform periodic testing to verify trip functionality.
