      What is a circuit breaker?

      A circuit breaker is an electrical protection device that automatically interrupts power when faults like overloads or short circuits occur. IPD’s range includes MCBs, MCCBs, and ACBs suitable for different load capacities, ensuring safe operation in residential, commercial, and industrial switchboards. Explore options from 6kA miniature breakers to 1600A moulded case breakers. 

      A circuit breaker is a safety device that automatically protects electrical circuits from overloads, short circuits, and faults. It ensures the safety of people, equipment, and buildings by interrupting the flow of electricity when abnormal conditions occur and faults like overload or short circuits occur.

      What is a residual current device (RCD) or RCBO?

      RCDs and RCBOs detect residual currents caused by earth faults, providing protection against electric shock and fire hazards. IPD’s RCBOs combine residual and overcurrent protection in a compact unit, available in 16A, 20A, and 32A options for single and three-phase systems.

      What is the difference between an MCB and MCCB?

      MCBs (Miniature Circuit Breakers) are ideal for low current ratings, typically up to 125A, while MCCBs (Moulded Case Circuit Breakers) handle higher loads up to 1600A that also have a higher fault level up to 200ka. IPD’s ABB MCCBs feature adjustable trip settings for flexible overcurrent and short circuit protection, suited for industrial applications.
