Bulletin 1489 DC Circuit Breaker

Bulletin 1489-D Circuit Breakers

Specially designed for higher voltage DC circuits with a permanent magnet to direct the arc into the arc splitters.
Field-mountable options for selective applications
IP2x Finger-Protection (Front)
North America certifications: UL 489, CSA C22.2 No. 5
International standards: CE Marked for IEC 60947-2 standards for worldwide acceptance
10 kA interrupt rating
UL/CSA — 1 pole: max. 125V DC, 2 pole: max. 250V DC
IEC — 1 pole: max. 250V DC, 2 pole: max. 500V DC
A positively trip-free mechanism (breaker operation cannot be defeated by holding the handle in the ON position)
Trip curves: C
Superior shock and vibration resistance capabilities — helps to prevent nuisance tripping
Mounts on DIN Rail
Wire connect, follow polarity requirements
