Product questions
What coil voltage does ABB 1SBH141001R8431 require?
The AC control coil is rated 110 V at 50 Hz or 110–120 V at 60 Hz. Check the control supply and frequency against the installed relay before ordering.
How many contacts does the N31E-84 relay have?
It has four auxiliary contacts: three normally open and one normally closed (3 NO + 1 NC). It is intended for switching auxiliary and control circuits.
Is the 16 A rating the switching current for every load?
No. The 16 A figure is the conventional free-air thermal current at 40 °C. The operational switching rating depends on the load and voltage; for AC-15 it is 4 A at 220–240 V and 3 A at 400 V.
What should I check before replacing an existing contactor relay?
Compare the complete part number, AC coil voltage and frequency, contact arrangement, terminals and dimensions with the installed unit. Equipment-specific fitment is not established; provide the equipment model and serial number for verification.
What are the dimensions and terminal type of this relay?
The relay measures 44 mm wide, 74 mm high and 74 mm deep, and has screw terminals. Check the available panel space and wiring requirements before ordering.
