ETA Circuit Breakers has introduced a 24VDC power distribution system for use at the device level in automated process control, production plants and power plants.

A single ETA SVS09 distribution board provides plug-in sockets for electronic and thermal-magnetic circuit breakers to protect each of 10 outputs from the effects of overloads and short circuits.

At the same time it offers an integrated alarm-handling function for single and group signalisation.

The ETA SVS09 power distribution system can be built up of cascades of individual boards designed in a master/slave mode, with up to five slaves to each master.

This cascading allows plant equipment, such as transducers, actuators, valves, distributed PLCs and intelligent terminals to be clustered into function groups and incorporated in the plant’s overall alarm-monitoring system.

This offers cost and space savings in the design of control cabinets.

Each load circuit interrupted by an overload or short circuit generates a single alarm: the individual circuit breaker can be simply re-set manually.

At the same time, by using a plug-in signalisation module, a group alarm is generated for the whole cascade, master plus slaves: this group alarm can be acknowledged by a momentary switch/relay/PLC, locally or remotely, immediately reactivating the group-signalling function of the cascade.

The ETA SVS09 can be directly mounted on a DIN-rail.

The maximum load per position is 4A, while the maximum continuous load per SVS09 board is 30A.

All terminals are spring-loaded for rapid installation.

The SVS09 is suitable for electronic circuit breakers, such as the ETA ESS20 and ESX10, and thermal-magnetic circuit breakers, such as the ETA 2210, 3600 and 3900; all of which can be simply plugged in directly to the SVS09 base.
