- Robust Construction: Designed for high endurance and stable operation under continuous industrial electrical loads.
- Wide Compatibility: Fits seamlessly into GE panelboards, switchboards, and individual enclosures requiring J600 frame breakers.
Important Precautions & Usage Guidelines
- Safety First: Always de-energize and lock out/tag out the electrical system before installation, maintenance, or removal.
- Qualified Personnel: Installation and servicing must only be performed by licensed electrical personnel in compliance with local and national electrical codes (e.g., NEC).
- Torque Requirements: Ensure all line and load terminal connections are torqued strictly according to the manufacturer’s specified values to prevent loose connections, overheating, or arcing.
- Environmental Limits: Operate within specified temperature and environmental limits; avoid exposed high-humidity or corrosive atmosphere environments unless properly enclosed.
Product Applications
- Industrial Control Panels: Protects heavy machinery, large motor circuits, and feeder circuits.
- Commercial Power Distribution: Serves as a main or branch feeder breaker in switchboards and panelboards for office buildings and retail spaces.
- HVAC Systems: Used for protecting large commercial heating, ventilation, and air-conditioning units.
- Transformer & Generator Protection: Acts as line protection for primary or secondary feeds in distribution transformers.
