SHORT CIRCUIT AND OVERLOAD PROTECTION FOR ALL DEVICES

IEC standard 60947-4-1 make a distinction between two different types of protection, (called “coordination”), which are designated types “1” and "2".

Any short-circuit that occurs is cleared safely by either type of coordination.

The only difference between the 2 categories concerns the extent of the SSR damage caused by the short-circuit.

Type "1" coordination requires that in the event of a sh

ort-circuit, the Solid State Contactor does not endanger personnel or installations,

but permanent damage to the SSC is permissible. In this case the SSC may need to be replaced. For this type of co-ordination,

the use of fusing or circuit breakers adequate to protect the system and wiring from short circuits, (but not specifically considering SSC protection), can be used.

Type "2" coordination r

equires that under a short-circuit condition, the circuit is interrupted, the SSC does not endanger persons or installations,

and in addition the SSR will be able to operate after the fault condition is repaired.

Type of coordination 1

Note: All the Schneider Electric Thermal magnetic circuit breakers GV2 family (GV2ME and GV2P) is fully mechanical compatible with the DRC contactor using the GV2AF3 connection block.

(Conforming to the IEC60947-4-2 and UL508)

The DRC Series can accept the LAD7C1 module (pre-wiring kit allowing direct connection of the NC contact of relay LRD to the contactor)

When the LAD7C1 module is used, the common terminal for the control input is not anymore the ”A2” terminal of DRC but it is the “96” terminal of the overload relay.
