Power management company Eaton announces its eMobility business is expanding its high-voltage circuit protection solutions for electrified vehicles (EVs) with the introduction of Breaktor, an advanced circuit protection solution.
- Combines function of fuses, pyro switches and contactors into a single coordinated device
- Helps solve coordination challenge between fuses and contactors
- Offers fast, safe and reliable protection for high-power battery and inverter systems
- Less than 5-millisecond actuation up to 1,000V and 30,000 amps
- Improves vehicle safety and protects components from any level of overcurrent condition more effectively than traditional circuit protection methods
- Resettable like a circuit breaker, which enables reactivation following a functionality check, reducing cost for both the OEM and consumer
- Can work in tandem with vehicle’s safety systems in event of a collision, allowing quick disconnection of high-voltage battery from rest of the vehicle
- Self-triggering device able to sense a current spike and interrupt the circuit
- Current limiting feature in the event of a short circuit improves system level protection
- Independence from current direction allows for both charging and driving use under full electrical load
- Multiple configurations, including voltage levels and multi-pole configurations
