Transit & School Bus

Reliable components and intelligent systems for the use in city and school buses

Circuit protection and relays for reliable and efficient on-board electrical systems

Uptime, reliability and vehicle safety requirements are constantly increasing in transit and school buses. At the same time, electrification of drive train systems requirements are continuing to evolve. Electric mobility, new fuel efficiency standards and bus connectivity & digitization continue to drive innovation.

Your passengers rely on you to arrive on time

E-T-A's resettable automotive circuit breakers replace ATO® and MINI® blade-type fuses, allowing technicians to reduce the amount of time for trouble-shooting and avoid unnecessary vehicle downtimes.
