Marine Ratings

UL Marine Listed/CSA Certified Circuit Breakers (UL 489 Supplement SA)

The PowerPact H- and J-frame circuit breakers with thermal-magnetic trip units with D, G, J and L

interruption levels meet the UL 489 Supplement SA requirements for use on vessels of any length

under or over 65 ft. (19.8 m). The PowerPact H-, J-, and L-frame circuit breakers with Micrologic

electronic trip units meet the UL 489 Supplement SA for use on vessels over 65 ft. (19.8 m) in length.

Marine circuit breakers must not use aluminum or aluminum alloys for terminal connections and must

be calibrated at an ambient temperature of 104°F (40°C). Standard circuit breakers should not be

specified or used in the place of marine rated circuit breakers.

Circuit breakers can be ordered with the Marine SA listing by adding the suffix “YA” (marine) to the

catalog number.

UL Naval Listed/CSA Certified Circuit Breakers (UL 489 Supplement SB)

The PowerPact H-, J-, and L-frame circuit breakers with Micrologic trip units with D, G, J and L

interruption levels meet the UL 489 Supplement SB requirements for use on naval vessels. These circuit

breakers are subject to various vibration tests as described in UL 489 Supplement SB. Naval circuit

breakers must not use aluminum or aluminum alloys for terminal connections and must be calibrated at

an ambient temperature of 122°F (50°C). Standard circuit breakers should not be specified or used in the

place of navel rated circuit breakers.

Circuit breakers can be ordered with the Naval SB listing by adding the suffix “YA1” (naval) to the catalog

number.
