SECUR®LeanStreamer, NH in-line disconnectors
for fuses IEC 60269-2 / VDE 0636-2 size 00
VDE 0660 part 107 / EN 60 947-3 / IEC 60 947-3
3-pole switching
Outgoing connection top and bottom.
Arc chamber.
Shock-protected even with lid open and in park position.
Mechanical fuse retention.
Degree of protection IP30 (front side), degree of protection near terminal depends on installation.
Connection contacts:
– M8 screw; 2x M5 clamp, 12mm clear width
– Prism clamp terminal Cu, Al* 16 - 70mm 2 s(r), s(s), f +AE
(* Connections with aluminium conductors are not maintenance-free (see page 8/2)
For 60mm distance between busbar centres:
– screwless busbar contacting
For 100mm distance between busbar centres:
– screw-on connection to drilled busbars, screw M8
– mounting without drilling using a terminal clamp
For 185mm distance between busbar centres:
– with an adapter
for screwing onto undrilled busbars, screw M12
mounting without drilling using a terminal clamp
– with a double adapter
for screwing onto drilled busbars, screw M12
Type 3-pole switching
Type of current AC (50 - 60Hz)
Rated operating voltage (Ue)** 690V AC
Rated insulation voltage (Ui)** 1000V
Rated surge withstand capacity (Uimp) without fuse monitoring** 8kV
Rated operating current (Ie)* 160A
Utilisation categories AC-22B (690V)
without fuse monitoring** AC-23B (400V)
AC-23B (500V 125A)
Conditional rated short-circuit current*** 50kA
For VDE 0636-2 NH fuses of all operating classes with power dissipation per phase
* During continuous operation, the rated load factor specifi ed according to
VDE 0660 part 500/EN 60 439-1, table 1, must be observed.
12W
For AC-23B, the distance to earthed parts must be at least 50mm at the top and 25mm at the side.
** Fuse monitoring Ue, Ui 400V AC, Uimp 4kV, level of soiling: 2 (mains connections)
*** Type tested with fuses of characteristic gL/gG.
Pilot switch for lid position indication:
2 (changeover) switches can be used
Rated operating voltage (rated operating current) 250V AC (5A), 30V DC (4A)
Electronic fuse monitoring:
2 LEDs
with latching properties or remote reset, programmable using
2 changeover switches
2 x Cu 2.5mm 2 solid conductors, DIN 46 288 or
2 x Cu 1.5mm 2 stranded conductors with sleeves, DIN 46 228-1/-2/-3
The internal resistance of the measuring needle lies above the MOhm level and thereby meets
VDE requirements regarding contact voltage (>1000 Ohm/V.)
To release turn off the upstream main switch.
