Miniature Circuit Breakers are electromechanical devices which protect an electrical circuit from an overcurrent. The overcurrent, in an electrical circuit, may result from short circuit, overload or faulty design. A MCB is a better alternative to a fuse since it does not require replacement, once an overload is detected. Unlike fuse, a MCB can be easily reset and thus offers improved operational safety and greater convenience without incurring large operating cost.
Red & Green flag indication provided below the knob gives indication of positive electrical ON/OFF contact status irrespective of mounting or knob position even from a distance.
Easy Mounting Strong hold on DIN Rail
Quick & Efficient Arc Quenching
Power Loss values upto 70% lesser than specified by IEC/IS, making Poly shied MCB one of the most energy efficient MCB.
Easy to Operate ON / OFF Marking to Know the status of MCB
No dismantling of busbar to remove MCB – Unique mounting assembly allows to remove single MCB from shorting busbar without disturbing other MCBs.
No accidental Contact/ Shock from live part during installation
Low let- through energy I T under short-circuit conditions ensures longer life of contacts and reduces thermal stresses in the distribution circuit.
The line or load can be connected to either side of the Polycab MCB without any reduction in Performance.
Reduces Body Temperature and keeping it cool to provide better performance
Ease of Clamping
Neutral pole is also protected against short circuit. so even if short circuit occurs at the neutral side, appliance or connected device will be protected.
