Miniature Circuit Breakers (MCB)

Miniature Circuit Breakers (MCBs) ensure electrical safety in homes, offices, and industrial applications by safeguarding electrical installations against overloads and short circuits. Upon detecting a fault, MCBs automatically cut off the electrical circuit, preventing wire damage and reducing the risk of fire. They incorporate two tripping mechanisms: a delayed thermal mechanism for overload protection and a magnetic mechanism for short circuit protection.

For over a century, we have pioneered MCB innovation and expanded our product range to meet diverse application needs worldwide. Our MCBs adhere to global standards such as IEC, UL, and CSA, ensuring universal compliance and maximum safety for buildings, assets, and infrastructure.

Residual Current Circuit Breaker (RCCB)

Residual Current Circuit Breakers (RCCBs) are essential safety devices designed to detect and trip in response to electrical leakage currents, thereby preventing electric shock from indirect contacts. They must be installed in series with an MCB or fuse to protect against thermal and dynamic stresses caused by overcurrents. RCCBs also serve as the primary disconnecting switches upstream of any connected MCBs, such as those found in domestic consumer units.

  • Safety Function : Detects and trips upon detecting electrical leakage currents, ensuring protection against electric shock.
  • Series Installation : Requires installation in series with an MCB or fuse to safeguard against overcurrents and thermal stresses.
  • Main Disconnect : Acts as the main disconnecting switch upstream of derived MCBs within installations like domestic consumer units.

RCCBs are integral to maintaining electrical safety in residential, commercial, and industrial settings, offering crucial protection against hazardous electrical faults.
