Product questions
What coil control voltage does ABB 1SBH136061R2140 accept?
The NFZB40E-21 is rated for 24–60 V AC at 50/60 Hz or 20–60 V DC. Check the actual control supply and its fluctuations against the applicable limits before selecting it; the coil rating is not the contact switching voltage.
How many contacts does the NFZB40E-21 have, and are they normally open?
It has four normally open contacts and no normally closed contacts in the base relay. The contact configuration should be checked against the circuit requirements before replacement.
What current can the 1SBH136061R2140 contacts switch?
The permissible operational current depends on voltage and utilization category. For example, the AC-15 rating is 4 A at 220–240 V AC and 2 A at 500 V AC; the DC-13 rating is 6 A at 24 V DC and 2.8 A at 48 V DC. Do not use the 16 A thermal current as a universal switching rating.
How is the NFZB40E-21 mounted and connected?
It uses screw terminals and can be mounted on TH35-7.5 or TH35-15 DIN rail, or with two diagonally placed M4 screws, which are not supplied. Check the available panel space and connection requirements before ordering.
