Positive safety relays
There are many applications where safety is
very critical and it is important to use electrical
equipment which ensures that dangerous
machine movement cannot occur when a fault
is detected with the moving contacts during
the cycle which the fault is indicated.
Regulations and standards have been written
to ensure that safety is maintained:
• United States ANSI B11.19-1990
ANSI B11.20-1991
• Germany SÜVA
ZH1/457
• France INRS
• United Kingdom BIA
• Switzerland SA
The ABB Type N & NL 4 and 8 pole relays are
designed with “Positive Guided” contacts
and fulfi ll the regulations or standards shown.
The relays can provide positive safety for the
N.O. and N.C. contacts which assure that
the N.O. contacts will not close before any
N.C. contact opens. Therefore, if one of the
contacts weld due to abnormal conditions
in the control circuit, the other contacts will
also remain in the same position as when the
welding occurred. This means that the open
contacts must maintain an air distance 0.5mm
when the coil is energized at 110% Vc or
when it is de-energized.

General information
Type NL & TNL, DC operated
Type NL
Description
• Magnetic circuit variants: NL types: d.c. operated with solid magnetic circuits.
• 2 versions: 4 pole or 8 pole
The width of 8 pole devices is identical to that of 4 pole devices; only the
depth is increased.
• Bifurcated auxiliary contacts.
• Alone or mounted with a 4 pole CA5 auxiliary contact block, these devices
offer “positive safety” between their auxiliary contacts.
Application
Type NL control relays are used for switching auxiliary circuits and control
circuits.

Type TNL
Description
• Magnetic circuit variants
– NL types: D.C. operated with solid magnetic
circuits.
– TNL types: D.C. operated with solid magnetic
circuit and large coil voltage range.
• 2 versions
– 4-pole/1-stack or 8-pole/2-stack
– The width of 8-pole devices is identical to that of
4 pole devices; only the depth is increased.
• Double sharp auxiliary contacts.
• Alone or mounted with a 4-pole CA 5 auxiliary contact block, these devices offer
"positive safety" between their auxiliary contacts.
Application
Type NL and TNL control relays are used for switching auxiliary circuits and control
circuits.

Holes for screw mounting (screws not
supplied). Distances between holes
according to EN50002.
Terminals delivered in open position
with captive screws (screws of unused
terminal should be tightened).
Screwdriver guidance for all screws
makes it possible to use motorized
screwdrivers.
All terminals provide protection against
accidental direct contact with live parts
according to VDE0106 – Part. 100.
