MA- Series

Three Phase Adjustable Trip

Miniature Circuit Breakers/

Manual Motor Controllers

The MA was designed to handle the high

inrush loads of 3 phase transformers,

power supplies, motors, etc. The MA

protects wiring and equipment from

damage caused by the three major

classes of over-current, yet greatly reduc-

es the number of nuisance trips in high

starting and inrush current circuits.

An IEC device with excellent ratings under

a UL listing at 480Y/277V (including group

ratings) and at 500V under international

standards, the Altech/ABL Sursum MA

provides short and long term cost effective

circuit protection for USA and/or export

applications. The short term advantages

include: (1) adjustable thermal trip allows

finalization of initial designs before

procurement of the load equipment is

complete; (2) snap-on mounting for readily

available, internationally standardized DIN

Rail saves panel layout design time as well

as installation and change labor; (3) large

cage-clamp terminals with screws suitable

to power screwdrivers, simplifies and

speeds wiring; (4) convenient switched

disconnect during factory testing and/or

initial start-up saves time and aggravation.

The key long term advantage is customer

satisfaction and proven over-current pro-

tection of wiring and equipment (and the

lack of rework/repair costs).

Note: HEA - Horsepower Equivalent Amperes, the nominal amperage assigned to standard motor horsepower ratings in design guide tables such as

NFPA-70 Tables 430-248, 430-249, 430-250; UL1077 Table 16.2; CSA - C22.2 No. 235-M89 Tables 44 and 45; CSA-C22.2 No. 14-M91 Table 19, etc.

Multiply HEA values (in parenthesis) by 1.1 if power factor is 90%, and by 1.2 if power factor is 80%.

a The standard-circuit short-circuit rating is 14kA for all types. Group ratings can be used in a standard circuit (e.g., MA1.0U at 42kA), but a higher
