- high electrical and mechanical durability
|
Compact design for 3-pole and 4-pole
versions
Both have the same styling, using the same materials, and have the same
mechanical and electrical design.
- 3-pole : 11 ratings from 7.5 to 100 HP
- 4-pole : 6 ratings from 25 to 125 A
A harmonious and complete series. |
 |
Accessories common to the whole series
One model (at most two) of each type of accessory fits all the
"A" series contactors. |
 |
|
Easy to integrate with your
own design
|
 |
Extremely compact
- whether for high or low ratings, all the contactors are extremely
compact:
- 236 cm3 for a power rating of 15 HPB with the A16 contactor: a record!
- 90 x 148 mm front for a 100 HP rated contactor (3-pole)
Without compromise to safety or performance.
- lower coil consumption:
- temperature rise is limited enabling designers to increase the population density of
components thus reducing cabinet dimensions
Control transformers can also be reduced in size for further savings.
|
Unrestricted benefits
- an "A" series contactor can directly replace another model
- the new contactors keep the advantage of fast fixing on EN rails
- excellent insulation between power and control circuits (conforming
to the strictest standards)
A design valid world-wide
- UL and CSA approved
- dual frequency coils (50 Hz and 60 Hz) for standard voltages
- technology complies with present and future voltage standards
- compliance with the latest international standards
- recyclable plastic materials, phosphorus- and halogen-free
- cadmium-free contacts
- supported by the world-wide ABB network
|
Easy to integrate accessories
- one range for all the "A" series contactors
- auxiliary contact blocks available in front - or side-mounted
versions
|
|
Designed for easy and safe
installation
|
 |
Clear, legible markings
On the box as well as on the product:
- easy identification, fast selection and simplified verification
- increased safety from the warehouse up to the workshop
|
Easy installation of accessories
- clip-on accessories
- surge suppressors connected when clipped-on
- easy change of accessories, unlocking by lever
|
 |
  |
Engineered for fast connection...
Combining all these benefits:
- all terminal screws are on the front for power and control
- one type of screw pozidriv No.2 (for A9 to A40)
- terminals delivered in open position with captive screws
- cable guides for faster conductor insertion
- coil terminals on the wiring side:
- two terminals A1 and A2, on the upper side
- one terminal A2 repeated on the lower side
...with safety in mind
- all terminals are marked on the front
- function confirmed on auxiliary contact blocks (NO or NC)
- terminal technology optimized for good cable grip
- live parts protected against direct touch
- closed or open state visible from the front
|
|
One range of high-performance
accessories
|
Rational and versatile
- every function is multiple-choice
- for most functions, one or two types of accessories are sufficient
for all the contactors in the "A" series
|
 |
Choice of auxiliary contact
- front - or side-mounted
- each model fits all the contactors in the "A" series
|
 |
Contact quality ensures performance
Auxiliary contacts benefit from ABB wiping contact technology:
- reliability even for low-level signals (standard 5mA, 17V)
- high thermal current
|
 |
Open option interlocking
- mechanical interlocking with integrated electrical interlocking for
the whole series
- mechanical-only interlock available as an option (from A9 to A40)
- interlocking possible between contactors with different ratings
|
 |
|
A new degree of reliability
|
 |
Built-in durability
- new shock-resistant material
- high ratings even at 600 V
- 1000 V insulation voltage (Ui)
- high tracking performance
- high mechanical durability (contactor successfully tested for over 20
million operations)
- high electrical durability
|
 |
This contactor has successfully passed a Type 2 (IEC
947-4-1) short-circuit test at 50 kA, protected with fuses.
A further 1000 V dielectric test proved its main characteristics remained intact, enabling
on-going normal use. |
 |
Built-in safety
- improved insulation between control and power circuits
- all live parts are protected against direct touch
Proven again and again
- every model of contactor and type of accessory has been extensively
tested in our certified laboratories (LOVAG, UL)
- test procedures are those approved by UL and LOVAG (ASEFA, ...)
- our test requirements are equal to or higher than the standards
