Salient features:
�
�Right aligned design to offer better utilization of space,
especially in a multi-tier panel design
Unique breaker front-facia architecture displays the electrical
accessories equipped on the ACB (with rated control voltage
& type of operating voltage)
�Superior safety features - arc chute interlock, smart racking
shutter, ready to close.
�Modular & snap-fit accessories such as UVR, SR, CR,
redefine the modularity on time scale of 5 mins.
�Ease of on-site convertibility from Manual to Electrical &
Fixed to Draw-out version
�Unipolar, snap-fit control terminals for independent 2
termination of 2 wires of up to 2.5 mm each
�ON & OFF buttons can be independently padlocked to
prevent unauthorized access
�Racking shutter can be padlocked to prevent inadvertent
racking operation
�Upto 3 breakers can be mechanically interlocked using
bowden cable. The Interlock is suitable for fixed, draw-out or
a combination
