Current Range (Ampere) Working Principle

HPL intelli TAB range of MCCBs are available in the These MCCBs work on Current Limiting principle. In case of any fault, the breaker’s tripping
following Frame sizes in 3-Pole & 4-Pole versions: mechanism opens the circuit so fast that very low energy (I2t) is released in a very short time so
that the entire system connected on the Load side is fully protected. This is achieved by
• Frame-2: 63A, 80A, 100A, 125A, 160A, 200A, 250A
• Frame-3: 250A, 315A, 400A, 500A
• Frame-4: 500A, 630A, 800A • Reversing current mechanism opens the contacts fast
• The intelligent Arc Interrupter
• Arc guided rapidly away from the separating contacts and
towards the arc chamber
• Quick arc quenching in the arc chamber

As a result, there is substantial reduction in the peak

current which reduces the overall electro-thermal dynamic
stresses produced in the system during fault conditions
helping the downstream devices to be SAFE & SECURED.
Moreover, during fault condition, the current transformers
fitted in the circuit of each phase senses the current and
sends signal to the tripping device through the electronic
circuit and trips the breaker. For discrimination, the
tripping time and respective tripping current can be set
with the help of Piano type DIP switches provided on the
front of the breaker.
