The megatrends of electrification and automated driving are leading to a rapid change in E/E architecture. Hybrid and electrical drive concepts as well as redundant on-board electrical systems make higher demands with regard to protection solutions and relays.
E-T-A specialises in this area, fulfils the requirements of the automotive standards ISO 16750 and IATF 16949 and develops solutions for the vehicles of tomorrow. Our solid state relays are a good example as are our 48V protection circuit protectors, which are already available. Together with our customers we also design hybrid switchgear for up to 1,000 V VDC.

With E-T-A’s autoreset circuit protectors you minimise complaints due to short circuit and overcurrent. Your applications are protected against improper use by the vehicle user.
- Air conditioning compressors, pumps and fans

E-T-A solid state relays in micro design are particularly suitable for applications that must be switched frequently and quickly.
- Quiescent current free overcurrent and short circuit protection
Quiescent current free overcurrent and short circuit protection
MOSFET technology produces continuous quiescent current and can lead to a total battery discharge in “Always On” applications. E-T-A’s autoreset circuit protectors do not produce quiescent current, have only a minimal voltage drop during operation and are particularly attractive due to the ECU integration option via SMD reflow soldering.

E-T-A solid state relays have a long typical life and are well suited for the use in vehicle interiors, as they switch completely silently.
- HV contactors and HV protection elements
HV contactors and HV protection elements
Providing highest safety and reliability despite system voltages of 800 V and more, high operational and charging currents, and extreme short circuit currents, are demanding challenges for HV components and systems. E-T-A finds new solutions for the challenges of the future.
- Electronic fuse protection and power distribution
Electromechanical relays and fuses quickly reach their limits in highly available on-board electrical systems. Electronic switching and protecting offers many benefits regarding speed, typical life, frequency, adjustability of characteristic curves, overvoltage protection or in terms of inrush current limitation.

Our solid state relays switch noiselessly and can therefore be installed in the passenger cabin and directly into the existing on-board electrical system. They do not have moveable contacts and therefore allow – unlike mechanical relays – wear-free switching of high inductive loads.
Our well-proven circuit breakers help avoid complaints and increase your vehicles’ reliability. They often fit into the frequently used ATO® and MINI® terminal blocks and replace conventional blade-type fuses.
The low holding current of our solid state relays ensures lower temperatures in power distribution systems, reduces power consumption and fuel costs as well as CO2 emissions. In addition, solid state relays have a significantly longer life span than mechanical relays.
