Bus: Transit & School

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.

Industry Leader in Transit and School bus Power Protection

E-T-A is the industry leader in power management design for both School and Transit bus. E-T-A innovations include standard Din-Rail, socket mount and smart PC based designs. We are the experts in power management and protection for the bus industry. Virtually all of the OEM's work with E-T-A for components and custom power management systems.

Compact, robust and energy-efficient

Limited installation space, reliability expectations and minimum energy requirements determine our customers’ designs. Our electro-mechanical power relays were designed specifically with this in mind and are tested in accordance with ISO 16750.

Increase Equipment Reliability with Compact & Robust IP6K9K/IP67 Power Relays

E-T-A power relays are ideal for switching high current loads up to 300 amps as well as battery management in transit & school buses. The power relays are made with high-end and corrosion-proof materials, making them extremely robust and able to withstand environmental factors like shock, vibration, water and dust. The compact design and low weight enables flexible installation in demanding applications.
