Product questions
What control voltage does ABB 1SBH136060R2244 accept?
The NFZB44ERT-22 is rated for a control circuit voltage of 48–130 V DC or 48–130 V AC at 50 or 60 Hz. Check the actual control supply and operating limits before selection.
How many contacts does the NFZB44ERT-22 have?
It has eight auxiliary contacts: four normally open and four normally closed. The contacts are mechanically linked.
What load can the 1SBH136060R2244 contacts switch?
The rating depends on voltage and utilization category. Examples are 2 A at 500 V for AC-15 and 6 A at 24 V for DC-13. The 16 A free-air thermal current is not a universal switching rating.
How is the NFZB44ERT-22 mounted and connected?
It supports TH35-7.5 or TH35-15 DIN rail mounting, or diagonal mounting with two M4 screws, which are not supplied. Its terminals accept ring-tongue connections.
Is this contactor relay suitable for a railway control circuit?
The NFZB44ERT-22 is intended for auxiliary and control circuit switching in railway rolling stock. Suitability for a particular vehicle or replacement is not established: provide the equipment model, serial number, existing relay number and control voltage for verification.
