Microtek Miniature Circuits Breaker are the Solution to The Ever-Changing Need of Electrical Distribution in different sector like Residential, Commercial and Industrial. They are designed to provide improved Operational safety, Better Continuity of Service, Lower Operating Cost and Greater Convenience.

CONSTRUCTION

Miniature Circuit Breakers have precisely formed Modeled case & Cover of flame retardant High Strength thermo-Plastic material having high melting Point, low water absorption, High Dielectric strength and temperature withstand. The Switching Mechanism is independent, manual and trip free. I.e. the Breaker trips internally even if the Operating Knob is held is ON Position.

The Contact Mechanism Comprises of fixed & moving contacts Specially Designed for Reliability, Long life and anti-weld Properties. The ARC Extinguishing Devices Comprises of 13 Plates ARC Chute. The ARC Under the Influence of the magnetic Field and ARC Guide is moved into the ARC Chute Where it is Rapidly Split and Quenched. The tripping mechanism is thermal Magnetic

THERMAL OPERATION – The Thermal Operation Provides Protection From Moderate Overloads. Under Overload Condition, a Thermo-metallic Element (Bimetallic Strip) Defects Until it Operates a Latching Mechanism Allowing the Main Contacts to Open.

MAGENTIC OPERATION – The Magnetic Operation Provide Protection From Short Circuits Current by Actuates the solenoid and they by causing a plunger to strive the latching Mechanism Rapidly Opening the main Contacts.
