Scope

1.1
The requirements of this standard cover molded-case circuit breakers, circuit breaker and ground-fault circuit-interrupters, fused circuit breakers, high-fault protectors, and high-fault modules. These circuit breakers are specifically intended to provide service entrance, feeder, and branch circuit protection in accordance with the National Installation Codes in Annex B, Ref. No.1. This standard also covers instantaneous-trip circuit breakers (circuit interrupters) specifically intended for use as part of a combination motor controller in accordance with the National Installation Codes in Annex B, Ref. No. 1.

1.2
This standard covers molded-case switches and fused molded-case switches.

1.3
This standard covers devices rated at 1000 volts ac and 1500 volts dc or less and 6000 amperes or less.

1.4
The devices referenced in 1.1 and 1.2 are intended for installation in an overall enclosure or as parts of other devices such as panelboards. The acceptability of the combination will be determined when the complete product is investigated.

1.5
This standard covers circuit-breaker enclosures and accessory devices intended for use with the devices described in 1.1 and 1.2.

1.6
This standard does not cover low-voltage power circuit breakers covered in Annex B, Ref. No. 3 and Ref. No. 4 or supplementary protectors covered in Annex B, Ref. No. 5.

1.7
This standard contains supplements covering the requirements for molded-case circuit breakers for:

a) Marine Use;
b) Naval Use;
c) Uninterruptible Power Supply Use;
d) Classified Circuit Breakers;
e) Software in Programmable Components;
f) Additional Tests for Circuit Breakers with Electronic Overcurrent Protection;
g) Electromagnetic Compatibility (EMC) – Requirements and Test Methods for Circuit Breakers; and
h) Molded-Case Circuit Breakers with Additional Motor Overload Protection.
