Low Voltage Products
Application
NL.. contactor relays are used for switching auxiliary circuits and control circuits.Their low power consumption allows the direct control from
transistor PLC outputs.
Description
The NL.. contactor relays are of the block type design.
The NL Z.. contactor relays are of the block type design with a very low coil consumption of 2.4 W.
The TNL.. contactor relays are of the block type design with a large coil operating range.
Variant
– 1-stack contactor relays: 4-pole.
– 2-stack contactor relays: 8-pole, with mechanically linked contact elements.
Poles:
Control circuit: d.c. operated with solid core magnet circuit and low consumption
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 (
NL..ST version with spring terminals (page 30).
Quick fixing on mounting rail according
to IEC 715 and EN 50022 standards:
35 x 7.5 mm or 35 x 15 mm.
Location of side-mounted accessories
(on right or left hand side)
Holes for screw fixing
Distance between holes according to
EN 50002.
Stops for attaching front-mounted
accessories.
Terminal screws: Pozidriv (+,-) No. 2.
The width of 8-pole devices is identical to that of 4-pole devices; only the depth is increased.
