EBU10-TA2-003-AC230V-C-16 ETA Electronic circuit breaker

The electronic circuit breaker type EBU10-T, Electronic Breaker Unit, provides selective overcurrent protection for AC 230 V UPS systems (UPS). The unit consists of a miniature circuit breaker approved for short-circuit disconnections of up to 10 kA and adjustable electronics that perform measurement and evaluation tasks in a targeted manner. The product is available in the LS rated currents 4 A, 6 A, 10 A and 16 A characteristics B and C and is operated directly at the outgoing circuit of the respective UPS.

UPS systems often do not provide sufficient power in the event of a short circuit to trigger conventional miniature circuit breakers. The electronic AC circuit breaker can be individually adapted to the UPS and thus reliably trips in the event of a short circuit. Thanks to the optimum setting of the rated load current, an overload in the load circuit is also detected and switched off in a targeted manner.

This prevents the entire output voltage of the UPS system from being switched off fatally.thanks to the Electronic Breaker Unit, EBU10-T
, UPS systems can be dimensioned around 1/3 smaller than before because no additional line reserves need to be provided for tripping. EBU10-T increases system availability, reduces overall costs and noticeably simplifies planning.

Key features:

Electronic overcurrent protection using electronic AC circuit breakers is ideal for the selective protection of uninterruptible power supplies (UPS) in industrial systems. With EBU10-T, energy security is ensured by AC UPS systems.

• Increased system availability through effective protection
• Reduction in overall costs thanks to 1/3 more efficient design
• Simplification of planning through variable overcurrent protection
