## Item description 

## Short description: 

WAGO's Current and Voltage Tap for 185 mm² (350 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, the current and voltage tap can be quickly and easily mounted into the jumper slot of WAGO's 185 mm² (350 kcmil) high-current through terminal block. An integrated fuse reliably protects downstream energy meters. An integrated current transformer (conversion ratio: 350 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 185 mm² (350 kcmil) high-current through terminal block 

- Integrated current transformer (350 A/1 A)
