Reliable power safety of UPS units (AC230V)

Permanent power supply even in the event of a power failure

UPS means “uninterruptible power supply”. These systems are used to ensure permanent power supply even in the event of a mains failure.
The current dilemma is: The current supplied by the UPS is not sufficient to magnetically trip the overcurrent protection. Hence, the entire UPS system will be disconnected. The so-called “uninterruptible power supply” will interrupt!

E-T-A unveils a world first: the EBU10-T (Electronic Breaker Unit), a newly designed hybrid protective element for a stable energy security of UPS systems.

Type EBU10-T - the solution for reliable power safety

The E-T-A circuit breaker type EBU10-T for AC 230 V consists of an MCB approved short circuit interruptions up to 10 kA and of an add-on electronic circuitry, taking over measurment and evaluation tasks. The product is available with the typical MCB ratings 6 A, 10 A and 16 A with B and C characteristics and is directly operated at the output of the corresponding UPS.



  • Increases system availability through effective protection
  • Easy planning with a variable overcurrent protection
  • Reduction of overall costs through 30 percent more effectivity –  savings of 1.000 € already in the first year
  • Provides reliability and meets the trip time requirement to VDE 0100-410 (operator protection)
