EBU10-T – Electronic Breaker Unit for UPS operation

EBU10-T  Electronic Breaker Unit

The mechatronic circuit breaker type EBU10-T from E-T-A provides selective overcurrent protection in AC 230 V UPS systems. The unit consists of an MCB approved for short circuit interruptions up to 10 kA. The second element is an add-on electronic circuitry for 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.

Uninterruptible power supplies only provide a limited current in the event EBU10-T – Electronic Breaker Unit for AC 230 V Power safety for UPS operation of a short circuit. The current provided by the UPS is not sufficient to trip a thermal-magnetic overcurrent circuit breaker. Thus – in the event of a failure – the entire UPS system will be disconnected.

The EBU10-T type can be adjusted to the actual load conditions and the capability of the UPS unit in question by means of two selector switches. The device will reliably trip in the event of a failure. And only the load path concerned will be disconnected. All other paths remain unaffected. The EBU10-T unit tolerates switch-on operations and the corresponding high inrush currents.
