Application Information
The KOMATSU 198-06-62840 Circuit Breaker is installed within the machine’s electrical power distribution system, where it protects high-current circuits supplying major electrical components. When current exceeds the rated 105 A threshold due to an overload or short circuit, the breaker interrupts the circuit to prevent damage to wiring harnesses, relays, controllers, and electrical accessories. Once the fault has been corrected, the breaker can typically be reset, restoring normal circuit operation.
The circuit breaker is designed to withstand:
- High electrical loads
- Continuous machine vibration
- Shock loading
- Dust and moisture exposure
- Wide operating temperature variations
- Heavy-duty mining and construction environments
