IEC TC 23E – Circuit Breakers and Similar Equipment for Household Use

IEC Technical Committee 23E (IEC TC 23E) develops International Standards for circuit breakers and similar protective devices intended for household and comparable applications.
These standards specify the design, performance, testing, safety, and reliability requirements for low-voltage circuit protection equipment.

IEC TC 23E publications cover miniature circuit breakers (MCBs), residual current devices (RCDs), RCBOs, and other protective switching devices used in residential, commercial, and light industrial electrical installations.

The standards ensure effective protection against overloads, short circuits, and electrical faults while improving user safety and system reliability.
Manufacturers, testing laboratories, certification bodies, electrical contractors, and utility companies rely on IEC TC 23E standards to ensure product quality and compliance with international requirements.

These standards are widely adopted worldwide to support safe, efficient, and standardized low-voltage electrical distribution systems.
