3. Product Features
- Current Limiting Function: Through magnetic break technology, when a short-circuit fault occurs, it can limit the fault current to around the limit current (usually 250A), preventing excessive fault current from burning out equipment.
- High Reliability: The Spectra RMS series is GE’s core product, with excellent switching performance and service life.
- Modular Design: Adopts plug-in installation, which is convenient for quick replacement and maintenance.

4. Structure and Composition
- Magnetic Trip Coil: Responsible for quickly cutting off the circuit in case of high-current faults.
- Thermal Magnetic Mechanism: Provides overload protection (thermal) and short-circuit protection (magnetic).
- Contacts System: Responsible for actual on-off operations.
- Frame: Provides mechanical support and installation interface.

6. Installation and Maintenance
Installation
- Wiring: Wire according to the wiring diagram in the product manual to ensure firm wiring and reliable insulation.
- Grounding: The frame should be reliably grounded to ensure safety.
Commissioning
- Closing: Before turning on the power, close the breaker first to ensure mechanical locking.
- Opening: Before maintenance or component replacement, open the breaker to cut off the power supply.
Maintenance
- Regular Inspection: Check the wear of the contacts and replace them if necessary.
- Cleaning: Keep the breaker shell and internal vents clean to prevent overheating caused by dust accumulation.
- Function Test: Conduct regular mechanical operation tests and electrical characteristic tests.
