Item description
Short description:
WAGO’s current and voltage tap for 95 mm² (950 kcmil) high-current through terminal blocks provides the ideal basis for successful energy
management, because current and voltage are required wherever electrical power is measured.
A combination of current transformer and voltage tap, this solution can be quickly and easily mounted into the jumper slot of WAGO’s 95 mm² (4/0
AWG) high-current through terminal block.
An integrated fuse reliably protects downstream energy meters. An integrated current transformer (conversion ratio: 250 A/1 A) allows precise
current measurement per EN 61869-2 (accuracy class: 0.5).
The current output connectors are marked with S1 (black) and S2 (red). Both termination and removal of fine-stranded conductors is performed via
push-buttons. The 5-pole configuration (2 x S1 and 3 x S2) provides the following advantages:
Current transformer (S1 and S2) can be short circuited via jumper (2000-402)
Direct ‘Y’ point jumper on current transformer
The voltage is connected using a redundant terminal block.
Additionally, the current and voltage tap can be marked either using continuous marking strips or via WMB Multi Marking System.
Features:
Power data can be directly tapped into the power supply
Easy installation – simply insert the tap into the jumper slot of the 95 mm² (4/0 AWG) high-current through terminal block
Integrated current transformer (250 A/1 A)
Accuracy class: 0.5
Fuse-protected voltage path
Note:
Suitable for 2-conductor through terminal blocks for DIN-rail mounting (285-195; 285-194)
Suitable for 2-conductor through terminal blocks with mounting flanges (285-181; 285-184)
