Typ EBU10-T von E-T-A: Der hybride Schutzschalter ist speziell für die Absicherung von AC USV Anlagen konzipiert.


The hybrid EBU10-T circuit breaker (Electronic Breaker Unit) has been particularly designed for the protection of AC UPS systems. The unit effectively ensures a stable supply and thus real power safety. The circuit breaker consists of an MCB and an add-on electronic circuitry, which takes over measuring and evaluation tasks. The product is available with the typical MCB ratings 4 A, 6 A, 10 A and 16 A with B and C characteristics and is directly operated at the output of the corresponding UPS. The device can be adjusted to the capabilities of the UPS used. In the event of a failure the circuit breaker will disconnect only the faulty path. A selective protection of UPS applications is therefore ensured. The electronic circuit breaker EBU10-T can be adjusted to the current rating of the UPS and the rated current of the load by means of a rotary switch.
