MCB & MCCB

Circuit Protection: The Guardians of Electrical Safety

MCB & MCCB

  • With the increasing load of modern appliances and industrial machinery, reliable circuit protection is non-negotiable. Our “Best Seller” protection devices are selected based on high breaking capacity and reliability. 

  • We feature Type-C MCBs, which are the standard for inductive loads (like fans, AC motors, and pumps) common in Indian households and factories.

The Universal C-Curve Standard: Intelligent Load Protection

  • The modern replacement for the old “kit-kat” fuse. Our range of ISI-marked MCBs provides dual protection: Overload Protection (trips if you plug in too many devices) and Short Circuit Protection (trips instantly if live touches neutral).

  • These are “Current Limiting” devices (Class 3), meaning they quench the electrical arc within milliseconds, minimizing damage to your wiring. We primarily stock the C-Curve variant, which handles the initial start-up current of motors (ACs, Refrigerators, Water Pumps) without nuisance tripping, making it the perfect all-rounder for Indian installations.

Key Features & Specifications:

  • 10kA Breaking Capacity: Can safely interrupt a massive short circuit current up to 10,000 Amps.

  • Trip Indication: Clear “On/Off/Trip” window allows for easy fault identification.

  • Air Circulation Design: Grooved channels allow better cooling, preventing false tripping in hot Indian summers.

  • Configurations:

    • Single Pole (SP): For individual switching of lights/fans.

    • Double Pole (DP): Main switch for single-phase household supply.

    • Three Pole + Neutral (TPN): For 3-phase commercial/industrial distribution.

Adjustable Protection: Heavy-Duty Security for High Loads

  • When the load exceeds 63 Amps, professionals switch to MCCBs. These are the heavy-duty guardians of commercial buildings, factories, and apartment complexes. Unlike standard MCBs, our Best Selling MCCBs feature Adjustable Trip Settings, allowing facility managers to fine-tune the thermal and magnetic protection settings to match the specific load requirements of their machinery.

  • Built for durability, they utilize a high-performance arc chute system to safely contain and extinguish high-energy faults, protecting your transformer and main distribution panels.

Key Features & Specifications:

  • Adjustable Settings: Variable thermal (overload) and magnetic (short circuit) dials for precise protection coordination.

  • High Breaking Capacity (Icu): Typically 25kA, 35kA, or 50kA to handle industrial fault levels.

  • Robust Casing: BMC (Bulk Molding Compound) glass-reinforced plastic housing resists heat and mechanical impact.5

  • Applications: Main Low Voltage (LV) Panels, Capacitor Banks, and Generator output protection.
