IEC 60947-2 categorizes circuit breakers based on whether they offer intentional time delay for selectivity under short-circuit conditions: Category A iec 60947-2 pdf

IEC 60947-2 is an international standard that applies specifically to used in low-voltage electrical installations. It is a core component of the broader IEC 60947 series on low-voltage switchgear and controlgear.

There are a few ways to access the IEC 60947-2 standard: is part of a larger series of standards

A circuit-breaker may comply with both IEC 60947-2 and UL 489, but it requires dual certification.

Unlike general-purpose breakers found in residential homes (which fall under IEC 60898), IEC 60947-2 covers . These devices handle higher fault currents, offer adjustable trip settings, and are tested for more rigorous conditions.

Prevents a localized electrical fault from causing a total facility blackout.
