Ergonomic rotary handle with tri-color status indicator (green-connected, red-tripped, orange-fault). Transparent arc chute window enables visual contact position verification.
-
Modular Expansion Capability
Optional accessories include motor operators, auxiliary contacts, and undervoltage releases. Tin-plated terminals accept 25-120mm² conductors with torque range 15-35N·m.
Technical Specifications:
- Rated Current: 200A (adjustable 160-200A)
- Ultimate Breaking Capacity: 50kA
- Operational Endurance: 20,000 mechanical cycles
- Terminal Temperature Rise: ≤60K (at full load)
Application Scenarios:
Ideal for main circuit protection in distribution cabinets, motor control centers, and branch circuit protection systems. Commonly deployed in manufacturing plants, commercial complexes, and renewable energy installations.
Installation Guidance:
Maintain minimum 50mm clearance between adjacent units for heat dissipation. Horizontal mounting recommended with DIN rail or panel screw fixation. Regular functional testing advised every 6-12 months depending on operational environment.
Maintenance Notice:
Dust accumulation on moving parts should be removed using dry compressed air (<0.2MPa). Contact surfaces may be cleaned with electrical contact cleaner if oxidation occurs. Avoid silicone-based lubricants on mechanical linkages.
