Terminal wiring for electrical energy meters

Many people are messing up with the energy meter type descriptions.

There are two standards for the wiring of bottom-connected
energy meters.

  • DIN 43857
  • BS 5685

In meter- or test bench descriptions you can find various expressions, all with the same meaning.
 

DIN 43857 refers also to:
– DIN terminal
– asymmetrical connection
– sequential wiring
– LLLLLLNN (for 3 phase 4 wire meters)
– LLNN (for singlephase meters)
– AABBCCNN (for 3 phase 4 wire meters)

DIN wiring
El cableado DIN siempre tiene este método.

BS 5685 refers also to:
– BS terminal
– symmetrical connection
– LLLNNLLL (for 3 phase 4 wire meters)
– LNNL (for singlephase meters)
– ABCNNCBA (for 3 phase 4 wire meters)

BS wiring
The BS wiring always looks similar to this.

    1. Thank you for your message. The DIN 43857 refers only to outer dimensions and terminal wiring. In the example are only shown the three-phase 4 wire connections.
      For a quote we need some basic information like: single phase or three phase meter, nominal current and maximum current. Better you select a meter type from our energy meter overview and use the contact form for the RFQ.
