Eaton Breaktor Circuit Protection Solution

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
