ABB launches a new range of low power consumption DC contactors. With a maximum 3.5W power consumption, the AL contactors and NL contactor relays enable direct control by PLCs without the use of an interface relay:
ABB AL three-pole contactors are designed for control of power circuits and motors from 4kW (AL9) up to 18.5kW (AL40) at a voltage up to 690V AC (50Hz) and 440V DC. They include integral auxiliary contacts and are fitted with either a 3W or 3.5W operating coil. The AL contactors are also available in 4-pole versions in three ratings from AL9 to AL26. The NL contactor relays feature a 3W coil and are available with either four or eight poles.
The AL range is completed by the TAL and TNL versions which feature a large coil operating range (0.7 to 1.25 Uc). These contactors meet the main specifications and standards for traction applications and are available with the option of ring tongue terminals.
AL contactors are available with either cable clamps and double connectors terminals while the capability for mounting in non-standard positions offers additional installation flexibility. The whole range has an insulation voltage of 1000V and conforms to international standards such as UL, CSA and CCC (China).
The AL range has the same aesthetically appealing design as ABB's well established A range of block contactors from 4 to 400kW and shares a large selection of common accessories such as auxiliary contacts (front or side mounting), overload relays, mechanical/electrical interlocks and surge suppressors.
