Product questions
What control voltage does ABB 1SBH137001R1240 require?
The NF40E-12 coil is rated for 48–130 V AC at 50/60 Hz or 48–130 V DC. This is the control supply rating, not the switched-contact voltage rating.
How many normally open and normally closed contacts does the NF40E-12 have?
It has four normally open auxiliary contacts and no normally closed contacts in its standard configuration. It is a four-pole contactor relay for switching auxiliary and control circuits.
What are the NF40E-12 contact current ratings?
The rating depends on the voltage and utilization category: AC-15 is 4 A at 220–240 V AC, while DC-13 is 6 A at 24 V DC. The 16 A free-air thermal current is not a universal switching rating.
How is the 1SBH137001R1240 relay mounted and how much space does it need?
It supports TH35-7.5 and TH35-15 DIN rails or two diagonal M4 screws. Its listed body dimensions are 45 mm wide, 86 mm high and 77 mm deep; allow additional space as required for wiring.
