Weidmuller Terminal blocks
PE terminal blocks
Functional description:
PE terminal blocks establish the electrical and mechanical connection between copper conductors and the mounting support plate. They have one or more contact points for connection with and/or bifurcation of protective earth conductors
Relevant standards: IEC 60947-7-2
Fuse terminal blocks
Functional description:
Fuse terminal blocks are made up of one terminal block bottom section with a fuse insertion carrier. The fuses vary from pivoting fuse levers and pluggable fuse holders to screwable closures and flat plug-in fuses
Relevant standards:
- IEC 60947-7-3 in conjunction with
- VDE 0636 IEC 60127-2
Feed-through terminal blocks
Functional description:
A feed-through terminal block is suitable for joining and/or connecting conductors and can have one or more connection levels that are insulated against one another.
Relevant standards:
- IEC 60947-7-1 / EN 60947-7-1
Multi-tier distribution terminal
Functional description:
Multi-tier distribution terminal blocks have several connection levels and are used to join and/or connect external, neutral and protective earth conductors with a conducting PE connection to the mounting support plate. The N conductor can be disconnected to measure the insulation.
Relevant standards:
- IEC 60947-7-1
- IEC 60947-7-2
- DIN VDE 0611-4
Test disconnect terminal blocks
Functional description:
You can use test disconnect terminal blocks to test and measure electric circuits in the absence of voltage. While the disconnecting point’s clearance and creepage distance is not assessed in dimensional terms, the specified rated impulse voltage strength must be proven
Relevant standards: - IEC 60947-7-1
Neutral conductor disconnect terminal blocks
Functional description:
Neutral conductor disconnect terminal blocks have one longitudinal disconnector for connection to a neutral conductor busbar. The longitudinal disconnector is used to measure the insulation resistance against earth. It also enables simple testing without any need to disconnect the neutral conductor
Relevant standards:
- IEC 60947-7-1
