Product questions
What coil voltage does ABB 1SAH107171R9900 use?
The MCRC022ATWJ has a nominal 110 V DC control coil. ABB lists an extended range of 77–143 V DC, with limits on the number of additional auxiliary contacts at the wider voltage range.
How many contacts does the MCRC022ATWJ provide?
It is a four-pole contactor relay with two normally open and two normally closed auxiliary contacts. It has no main contacts.
What current can the 1SAH107171R9900 switch?
Its rated operational current is 6 A at 240 V AC in utilization category AC-15; at 400 V AC the AC-15 rating is 4 A. The 10 A auxiliary-circuit thermal current is not a universal switching rating.
How is the MCRC022ATWJ mounted and how much space does it need?
It supports DIN rail or wall mounting and measures 45 mm wide, 48 mm high and 68 mm deep. Allow for the requirements of the installation and connected wiring.
Is the MCRC022ATWJ the correct replacement for my existing relay?
Confirm the full part number, 110 V DC coil, 2 NO and 2 NC contact arrangement, load ratings and mounting before ordering. Equipment-specific fitment is not established; provide the equipment model and serial number for verification.
