UL Marine Listed Circuit Breakers

Class 600

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

For use on vessels over 65 ft. (19.8 m) in length.

PowerPacT™ H and J circuit breakers with thermal magnetic trip units meet the UL 489 SA requirements on vessels of any length under or over 65 ft. (19.8 m). PowerPacT H, J, and L circuit breakers with MicroLogic™trip u nits meet the
UL 489 Supplement SA requirements 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 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)

PowerPacT™ H, J, and L circuit breakers with MicroLogic™ trip units meet the UL 489 Supplement SB requirements for naval vessels. These circuit breakers are subject to various vibration testing as described in UL 489 Supplement SB. Naval circuit breakers must not use aluminum or aluminum alloys for terminal connections and are calibrated at an ambient temperature of 122°F (50°C). Standard circuit breakers should not be specified or used in the place of naval rated circuit breakers.

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