UL Standard for Safety Molded-Case Circuit Breakers, Molded-Case Switches and Circuit-Breaker Enclosures

inactive
Organization: UL
Publication Date: 25 March 2015
Status: inactive
Page Count: 40
scope:

These requirements cover motor protection molded-case circuit breakers intended for use as service entrance, feeder, and branch circuit protection and, in addition, provides motor disconnect, short-circuit and ground-fault, and branch-circuit overload protection in accordance with the National Installation Codes in Annex B, Ref. No. 1. A circuit breaker used as motor and branch-circuit overload protection shall comply with the applicable requirements of the preceding sections of this standard, except as modified or added to by the requirements in this supplement.

These circuit breakers are intended to be used in combination with a contactor in accordance Annex B, Ref. Nos. 25 and 26, as a component of a Combination Motor Controller.

These requirements are not intended to replace requirements in the National Installation Codes which allow a standard circuit breaker to function also as a separate overload device in a motor branch circuit where the circuit breaker provides both motor branch-circuit short-circuit and ground-fault protection and motor overload protection.
