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 self-resetting circuit breakers from E-T-A, you minimize complaints due to short circuits and overcurrent. Your applications are protected from improper use by the vehicle user.

E-T-A solid state relays in micro design are particularly well suited for applications that require frequent and fast switching.
- Quiescent current free overcurrent and short circuit protection
Quiescent current free overcurrent and short circuit protection
MOSFET technology causes a constant quiescent current and can lead to deeply discharged batteries in "always-on" applications. Self-resetting circuit breakers from E-T-A do not generate quiescent current, have a minimal voltage drop during operation and additionally convince by the possibility of ECU integration via SMD reflow soldering.

E-T-A solid state relays have a long service life and can be used in vehicle interiors without any problems. They switch completely silently.
- HV contactors and HV protection elements
HV contactors and HV protection elements
System voltages of 800 V and more, high operating and charging currents as well as extreme short-circuit currents combined with maximum safety and reliability place high demands on HV components and systems. E-T-A finds new solutions for the challenges of the future.
Electromechanical relays and fuses reach their limits in high-availability vehicle electrical systems. Electronic switching and contactors offer many advantages in terms of speed, service life, frequency, adjustability of characteristics, overvoltage protection or also in terms of limiting the inrush current.

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.
