3. Product Features and Advantages
- Dual Thermal-Magnetic Protection: Integrates thermal protection (to prevent overload) and magnetic protection (to prevent short circuits), enabling long-term and instantaneous current interruption.
- Compact Structure: Adopts a molded case design with a relatively light weight (approximately 33 lbs), making it easy to install in distribution boxes or panels.
- High Interrupting Capacity: The 10kA interrupting capacity can quickly cut off current in the event of a circuit fault, preventing damage to electrical equipment.
- Standardized Design: Complies with international IEC standards, suitable for the global market, and equipped with standardized incoming and outgoing terminals.

6. Installation and Maintenance
Installation Recommendations
- Check Pole Spacing: Ensure that the pole spacing of the installation panel or distribution box meets the 1" standard.
- Correct Wiring: Pay attention to distinguishing between line (incoming) and load (outgoing) terminals to avoid reverse connection, which may lead to protection failure.
- Secure Fixation: Use bolts or screws to fix the circuit breaker in the distribution box to ensure it does not loosen in a vibrating environment.

- Secure Fixation: Use bolts or screws to fix the circuit breaker in the distribution box to ensure it does not loosen in a vibrating environment.
Maintenance Recommendations
- Regular Inspection: Regularly check the tightness of terminal bolts to prevent loosening caused by vibration or thermal expansion and contraction.
- Clean the Enclosure: Keep the enclosure clean to prevent dust accumulation from affecting heat dissipation.
- Test Trip Function: During planned shutdown maintenance, a tester can be used to test the thermal-magnetic trip unit to ensure its sensitivity meets the standard.
- Replacement Indication: If the circuit breaker trips frequently, it may be due to line overload; check the load or replace the circuit breaker with a higher current rating.
