In the range of molded case circuit breakers conforming with the UL 489 and CSA C22.2 Standard, ABB proposes an

entire range which covers current ratings between 15 A and 2500 A and interrupting ratings, at 480 V AC, which can

reach 150 kA.

The ranges available are as follows:

¨C circuit breakers for power distribution (fitted with thermomagnetic or electronic trip units starting from 100 A)

¨C circuit breakers with adjustable magnetic only trip units for motor protection (MCP: Motor Control Protection)

¨C molded case switches for use as isolators or switching devices for lines, busbars or parts of a plant (MCS:

Molded Case Switch)

With the introduction of the new Tmax UL series, a single-pole circuit breaker with interrupting rating of 18 kA

at 277 V AC is available on the American market for the first time.

480 V

All ABB circuit breakers in accordance with the

UL 489 and CSA C22.2 Standard can be

used in installations with wye or delta

distribution systems since use of the circuit

breaker at 480 V AC is guaranteed, even

for the smallest Tmax T1 size.

C O M PA C T D I M E N S I O N S

ABB molded case circuit breakers ensure

high performances in extremely small and

compact dimensions. Standardization of

the depth of the smaller sizes allows more

rational and less deep enclosure to be used

than in the past.

D O U B L E I N S U L AT I O N

Thanks to the double insulation technique,

with all ABB molded case circuit breakers*

the electrical accessories can be mounted

directly on field with the circuit breaker

installed: this allows considerable savings in

time and therefore in costs.

* Except for Isomax S8.
