Product questions
What coil voltage does ABB 1SBH101001R2031 require?
The NS31E-20 has a 24 V AC control coil rated at both 50 Hz and 60 Hz. It is an AC-operated relay; do not assume that a 24 V DC supply is suitable.
How many contacts does the NS31E-20 contactor relay have?
It has four auxiliary contacts: three normally open (NO) and one normally closed (NC). The contacts are mechanically linked.
How is the NS31E-20 mounted and how much space does it occupy?
It supports DIN-rail or screw mounting and has screw terminals. The relay body measures 45 mm wide, 68 mm high and 72.5 mm deep; allow additional space for wiring and any accessories.
What is 1SBH101001R2031 used for, and can it accept extra contacts?
This contactor relay is intended for switching auxiliary and control circuits. Its NS design allows front-mounted add-on auxiliary contact blocks; confirm the specific accessory and circuit requirements before ordering.
