Residual Current Circuit Breaker




Our Residual Current Circuit Breakers provide high protection against earth leakage. They are CE approved and are made 100% compliance with the IS: 12640-1:2008 and ISI standards. So, they surpass the quality parameter. We procure these RCCBs from reliable vendors and make them available throughout the country in time-efficient manner. We are reckoned among the leading Suppliers of Residual Current Circuit Breakers in Ahmedabad, Gujarat.

 

RCCB'S Operational Principle
Micron RCCB is a current operated device and is independent of line voltage conditions. This means that they provided protection even when there is voltage dip or the neutral conductor is interrupted. In a healthy system the vector sum of all currents in phases and neutral is equal to zero. The device senses inbalance or residual currents in the system and Disconnects Supply system.

 

Features :

  • State-of-the-art design
  • RCCBs are completely type tested in accordance with IS: 12640-1 :2008 and are 151marked.
  • CE marking fulfils the requirement of global standard.
  • Elegant appearance
  • High short circuit current withstand capacity with backup protection fuse
  • Equipped with finger protected connection terminals
  • The housing of RCCBis moulded from special grade engineering Plastic and flame retardant.
  • Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds
  • the rated sensitivity.
  • Test button 'T' is provided for periodic checkup.
  • Protection against direct and indirect lines.
  • Simple and Robust operating mechanism.
  • Dual Position Clip.
