Application
NL..ST, NL Z..ST and TNL..ST contactors are the spring terminal version of the NL-range.
The ST-range of contactor relays use ABB Entrelec's proven spring terminal technology giving the following benefits:

1SBC101139C0201
– 1-stack contactor relays: 3-pole + coil terminals on the same stack.
– 2-stack contactor relays: 7-pole + coil terminals on the first stack
Poles and coil:
Control circuit: d.c. operated with solid core magnet circuit and low coil consump-
tion coil. The coil must be energised from a d.c. supply and the polarity (+ and –)
must be respected.
Accessories: a wide range of accessories are available
Connection: the cables are connected via the front face with the possibilitly to use
two different types of cables with different cross-sections.
a fast connection on the front face, which saves labour time,
vibration proof,
no need to retighten the terminals saving maintenance labour time.
Clear marking of coil voltages.
Holes for screw fixing
