MP25, EL25 ... EL100 industry current sensors
Technical data

Utilisation
Sensors to measure DC, AC or pulsating currents with
a galvanic insulation between primary and secondary
2 circuits.
Type MP25P1: the rating (from 5 to 25 A) is deter-
mined via a combination of the primary connections
(see technical data: "Arrangement of primary terminals
and related characteristics").

General data Secondary connection
Direction of the current 3 soldering pins.
– MP25P1 type: A primary current flowing from pins 1- 5 to pins
6-10 results in a positive secondary output Unit packing
current from terminal M
– MP25P1 type: 40 per pack
– EL type: A primary current flowing in the direction of the
arrow results in a positive secondary output – EL type: 50 per pack
current from terminal M. – EL…BB type: 25 per pack.

Fixing Conformity
