(1) To connect cables with a c.s.a.>4mm2 and up to 10mm2 ,it is essential to use spectial connectors ,sold in bags lf 100 (reference:MC1-D-961860)
(2) If cable ends are used, choose the next size down (example: for 2.5 mm2,use 1.5mm2 )and square crimp the cable ends using a special tool

(1) Opening times depend on the type of contactor electromagent and its control mode .the closing time "C" is measured from the moment the coil supply is switched on to initial contact the main poles,the opening time "O" is measurd from the moment the coil supply is switched off to the moment the main poles separate.

Linked contacts conforming to draft standard IEC 947-4-5

Each contactor has 2 N/O and N/C contacts mechanically linked on the same movable contact holder

Mirror contact

The N/C contact on each contactor represents the state of the power contacts and can be connected to a PREVENTA safely module
