Description
The Bulletin 1489-A line includes:
ꢀ UL 489, CSA C22.2 No. 5
ꢀ 240V AC 0.5...40 A
Bulletin 1489-A Circuit Breakers for Branch Circuit protection are
available in 1-, 2-, and 3-pole construction and are rated 0.5...40 A
at 240V AC and 0.5...32 A at 480Y/277V AC for North American
applications (UL 489 and CSA C22.2 No. 5). The circuit breakers
also have a 1-pole 48V DC, 2-pole (series) 96V DC rating. For
EN\IEC applications the products are rated 415V AC, 48V AC
0.5...40 A.

Thermal Magnetic Circuit Breakers
The Bulletin 1489-A Thermal Magnetic Circuit Breakers are general- 11
purpose devices suitable for the majority of industrial, inverse time
circuit breaker applications.

ꢀ 1-pole 48V DC 0.5…40 A
ꢀ 2-pole (series) 96V DC 0.5…40 A
ꢀ 48V DC 0.5…40 A
They combine thermal and magnetic trip actions and provide
accurate overload and short-circuit protection for conductors and
