In principle, all Eaton miniature circuit breakers are type-tested and approved in accordance with either IEC/EN 60898-1 or IEC/EN 60947-2. The corresponding test marks are printed on the devices. Circuit breakers that fall within the scope of IEC/EN 60898-1 are primarily intended for use in domestic installations and are designed to be operated by non-experts. IEC/EN 60947-2 applies to circuit breakers in circuits with rated voltages up to 1,000 V AC, or up to 1,500 V DC.
