Magnum DS Switchgear Class UL 1066 Low Voltage Power Circuit Breakers

Notes

1 Interrupting ratings shown based on breaker equipped with integral Digitrip RMS trip unit. Interruption ratings for non-automatic breakers are equal to the published short time current rating. These

interruption ratings are based on the standard duty cycle consisting of an open operation, a 15-second interval and a close-open operation, in succession, with delayed tripping in case of short-delay

devices. The standard duty cycle for short time ratings consists of maintaining the rated current for two periods of 1/2 seconds each, with a 15-second interval of zero current between the two periods.

2 See Page V9-T1-40 for selection of trip unit and accessories. See Page V9-T1-40 for cassette selection for drawout breakers.

3 Magnum MDSL current limiting power circuit breaker with integral current limiters. Current limiter selected determines short time and maximum instantaneous trip rating.

Maximum voltage rating is 600 Vac.

4 Product to be tested. Contact Eaton for product rating.

5 Magnum MDSX current limiting power circuit breaker with fast opening contacts.

6 Contact Eaton for availability.

7 Breaker applied in a tested fan-cooled enclosure.
