Product questions
What control voltage does the ABB NFZ22E-21 coil require?
The coil is rated for 24–60 V AC at 50 or 60 Hz, or 20–60 V DC. Check the complete part number and supply voltage before selecting a replacement.
How many contacts does 1SBH136001R2122 have?
This four-pole contactor relay has two normally open and two normally closed auxiliary contacts. ABB describes them as mechanically linked.
Can the NFZ22E-21 be controlled directly by a PLC?
ABB states that the NFZ contactor relay can be controlled directly by a PLC output rated at least 24 V DC and 500 mA. Check the PLC output specifications and circuit design before use.
How is the ABB NFZ22E-21 mounted and connected?
The relay supports DIN-rail or screw mounting and has screw connections for the auxiliary circuit. Its listed dimensions are 45 mm wide, 86 mm high and 77 mm deep.
Does 1SBH136001R2122 have built-in surge protection?
Yes. ABB states that NFZ contactor relays have built-in surge protection, so an additional surge suppressor is not required for the coil.
