Product questions
What control voltage does ABB 1SBH137001R1422 require?
The NF22E-14 coil is rated for 250–500 V AC at 50/60 Hz or 250–500 V DC. This is the control supply rating, not the contact switching voltage; check the actual control supply before ordering.
How many contacts does the NF22E-14 relay have?
It has four mechanically linked auxiliary contacts: two normally open and two normally closed. It is intended for switching auxiliary and control circuits.
What current can the NF22E-14 contacts switch?
The rating depends on utilization category and voltage. For AC-15 it is 4 A at 220–240 V and 3 A at 400–440 V; for DC-13 it is 6 A at 24 V DC and 0.27 A at 220 V DC. Do not use the 16 A thermal rating as a universal switching rating.
How can the 1SBH137001R1422 contactor relay be mounted?
It fits 35 × 7.5 mm or 35 × 15 mm DIN rail, or can be fixed with two diagonally placed M4 screws. ABB specifies that the screws are not supplied.
Does the NF22E-14 require an external coil surge suppressor?
ABB specifies built-in surge protection for NF contactor relays and says an additional surge suppressor is not required for the coil.
