Description
This component serves as a protective overcurrent device in low-voltage electrical systems. It ensures circuit protection by interrupting current flow when the rated capacity is exceeded—preventing damage to connected equipment or wiring.
### Current and Voltage Ratings
Exact current rating: 3A. Operating voltage range up to 250V AC. Adheres to IEC and EN standards for operational safety.
### Design and Connection Features
Mountable on DIN rail systems (35mm). Compact design suited for tight control panels. Screw terminal connections ensure secure wiring; support single-strand or ferrule-tipped conductor insertion.
- Response time varies depending on fault severity.
- Not designed for direct DC applications unless compatibility checked.
- Should be tested periodically under load conditions—may degrade with age or wear.
