Product questions
What control voltage does the ABB NF44E-13 require?
Part 1SBH137001R1344 has a 100–250 V AC control range at 50/60 Hz and a 100–250 V DC control range. This is the coil supply rating, not a blanket rating for the switched load.
How many contacts does 1SBH137001R1344 have?
It is an eight-pole contactor relay with four normally open and four normally closed auxiliary contacts.
How is the NF44E-13 mounted and connected?
The relay supports DIN-rail or screw mounting and uses screw connections for the auxiliary circuit. Check the available panel space and wiring requirements before ordering.
Is 1SBH137001R1344 suitable for switching a 400 V control circuit?
Its published operational current at 400 V is 3 A; select it according to the actual load and applicable utilization category. Equipment-specific fitment is not established: provide the equipment model, serial number and circuit details for verification.
Does the NF44E-13 require a separate coil surge suppressor?
The NF contactor relay has built-in surge protection. Confirm the circuit requirements and manufacturer instructions before selecting additional protection.
