Trusted MCB Manufacturer in India
It is a Miniature Circuit Breaker. It is a current operated device. It protects against overloadand short circuit fault in electrical supply. The over load protection is achieved with thermaltripping mechanism and short circuit protection is achieved by Magnetic trippingmechanism.
Working Principle
STEP
01
Thermal Operation
The thermal Operation provides protection from moderate overload. Under overload condition, athermo-metallic element ( Bimetallic strip) deflects and it operates a latching mechanism allowingthe main contacts to open.
STEP
02
Magnetic Operation
In magnetic operation, large overloads or short circuit current actuates a solenoid causing aplunger to strike the latching mechanism rapidly opening the main contacts.

We are a leading MCB manufacturer in India, supplying safe, reliable, and durable electrical protection products to homes, industries, and commercial spaces across the country.
About Our MCB Manufacturing Expertise
Our team combines deep technical expertise with a strong commitment to quality, ensuring every Miniature Circuit Breaker (MCB) we produce delivers reliable performance and consistent electrical safety. Each MCB is a current-operated protective device designed to safeguard electrical circuits against overloads and short circuits. Overload protection is achieved through a thermal tripping mechanism, while short circuit protection is ensured by a magnetic tripping mechanism—providing long-lasting durability, precision, and dependable protection in every operation.
Our Complete Range of MCB Products
Step into a lineup designed to keep every electrical connection safe and reliable. Each MCB in our range is built to handle different load needs while offering stable protection for homes, offices, and industries.
Single Pole (SP)
Ideal for basic circuits, SP MCBs protect a single live wire, ensuring safety for small loads and essential electrical points. As a trusted single pole MCB switch manufacturer, we deliver reliable solutions for residential and commercial applications.
Double Pole (DP)
Made for circuits that need both live and neutral protection, DP MCBs offer stronger safety for larger appliances.
Four Pole (FP)
FP MCBs deliver complete protection across all three phases plus the neutral—great for high-demand installations.
Single Pole & Neutral (SPN)
A smart option for residential and light commercial use, SPN MCBs protect both live and neutral lines with one device.
Key Features of Our MCBs
Conforms to Latest Standard
MCB conform to the latest standard IS/IEC 60898-1:2002 in selected ratings.
Energy Saving
The low power loss as stipulated in the IS/IEC 60898-1:2002 has been taken care of in designing theMCB. The low power loss figures of MCB contributes significantly to the energy saving.
Din Rail Mounting
MCB's can be mounted on standard 35mm DIN Rail by snap action. No time wastage in installing and replacing the MCB.
Shock Proof
Finger and hand touch safe. Tested as per the test clause 9.6 of IS/IEC 60898-1:2002 protection against electric shock.
Housing
The housing of MCB is injection moulded from special grade PBT as per international specifications.The housing and other moulded components are fire retardant, anti-tracking and non hygroscopic.
Contacts
Contacts are made of special Silver Tip in copper strip, silver plated, ensuring higher life and maximum safety against contact welding and erosion. These contacts have low contact resistance resulting in reduced watt loss.
Operating Mechanism
MCB have a quick make & break Trip Free Mechanism. In the event of an over current or short circuit the MCB automatically interrupts all poles even if the MCB toggle is held in ON position, the handle always indicates the correct contact position.
Moderate Overload Condition
Detection of moderate over load conditions is achieved by the use of a Bimetal Overload Relay, which deflects in response to the current passing through it. The Bimetal Relay moves against the trip bar releasing the trip mechanism.
Perfect Connections
The design of terminals makes the wiring easier. Combination box type terminals with combination head screws on both sides with deep serrations ensures sparkless and firm connections. The biconnection facility simplifies connection in various application areas.
