Translating Technology
Into Real Benefits
AU Solutions for final distribution offer a unique blend of safety, convenience and
performance.
Each product in the AU Solutions range is designed to provide lasting benefits.
Lowest Watt Loss
Saves money and natural resources
MCBs from AU Solutions offer the lowest watt loss in the industry. On an average, the watt loss values are almost
55% lower than those prescribed by IEC.
Lower watt loss means lower power consumption, which directly translates into monetary savings. Beyond tangible
benefits, lower power requirement also hints at lower consumption of natural resources used for producing energy.
In a nutshell, these MCBs are a small, yet significant step towards sustainability.

Short-circuit Fault Indicator in MCBs
Easy diagnosis, saves downtime UNIQUE
With the unique short-circuit fault indication feature, one can BENEFIT
conclude if the MCB has tripped due to a short-circuit fault.
It helps in reducing downtime as the faulty phase and cause
of MCB tripping are easily detected.
If the MCB has tripped on 'overload', non-critical loads can be
switched off before switching the MCB on again.
In the case of a short-circuit fault, the location and cause
of the short-circuit should be identified and the necessary
corrective action should be taken.
Earth Leakage Fault Indication in RCDs
› Clear indication by yellow coloured flag
UNIQUE › Easy detection of occurrence of earth leakage
BENEFIT
Flexibility
› Flexibility in Termination
›› Bi-connect terminals offer busbar or cable
termination at both incoming and outgoing sides
› Line-Load Reversibility
›› Either of the sides of an RCCB can be used to
terminate supply or load
› RCCBs removability with busbar in place
›› This feature, with a uniquely designed DIN clip, offers
easy removal of DIN mounted RCCBs while the
connection busbar is in place with adjoining devices
›› Offers great flexibility in installation process
›› Reduces installation time
Communication Capability
For smart systems
With the communication capability of AU Solutions, one can
monitor and control various devices remotely.
The complete communication system can be deployed for
effective energy management.
RoHS Compliance
Environment-friendly
RoHS compliant AU Solutions do not use any substances which
are hazardous to the environment.PDF page 5 MCBs (Miniature Circuit Breakers) [8536]
