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.
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.
STATE OF THE ART DESIGN - Microtek Design is aesthetically superior and Built in with features like Center dolly. Clear marking o the technical parameters ON/Off Symbol Along. This Marking also help to enhance the design appeal of this range
EXCEPTIONAL ENDURANCE - The Products have been tested at high Electrical Mechanical endurance with the ambient Temperature of -5C to +55C.
ENERGY LIMITING CLASS ?- To ensure low let through energy to limit thermal and mechanical stress on cables.
BREAKING CAPACITY- The Devices in the range have a Breaking capacity of 10kA.
SPECIALLY DESIGNED ATC CHAMBER - 13 Plates ARC chute for effective ARC Quenching.
CONTACT INDICATION WINDOW- the Products are designed by considering user Friendliness into mind. The Visual Indications Help users to identify the positions of MCB, RED =ON, GREEN =OFF.
BI CONNECT THERMINALS- the Terminal size in devices adds convenience and Flexibility while wiring. The 25 Sq. mm Terminals are Designed to hold Cables Tightly Which Avoids loose Connection the BI-Connect Terminals Provides the Flexibility by allowing the Lines to be Connected Through wires and Bus Bars.
PROTECTION IP-20- We Realize the Importance of safety and have Designed the range in such a way that no live parts are exposed to human contact, thus making devices safe to use.
DUAL POSTION CLAMP- the Dual Positions Clamp Help in easy Mounting and Unmounting of the MCB.
TRIP-FREE MECHANISM- the MCB Trip Even if Knob is Held in on Position.
AIR FLOW CHANNEL- the Special air Flow Channels on the MCBs Allow the air to come out and helps to maintain the temperature inside while MCBs are adjoined with each other in the Dbs.
ISI/ CE MARKING- the ISI Marking on Our Range Guarantees That Our Products have passed all Quality Check and are the Safest Choice.
