- co-ordinated dimensions :- for easier panel configuration
New technology
- new high-resistance, environmentally friendly material :- improved shock resistance ; contains no phosphorus or and halogenated components
- terminals protected against direct contact :- high safety
- performance optimized with new design :- improved short-circuit capability- high electrical and mechanical durability
Compact design for 3-pole and 4-pole versions
- 3-pole : 11 ratings from 7.5 to 100 HP
- 4-pole : 6 ratings from 25 to 125 A
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
Easy installation of accessories
- clip-on accessories
- surge suppressors connected when clipped-on
- easy change of accessories, unlocking by lever
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
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.
- 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
