Introduction

NETWORK INTERLOCK DEVICE (NI)

The Network Interlock Device locks the breaker In

OFF position electrically and mechanically.

When this device receives a pulse all local

breaker functionality is disabled except the

tripping of the device on any over current fault.

On the receipt of a 2nd pulse normal operation is

re-instated. The presence of mains power does

not affect the locking and/or re-instatement of

this device. Each device has a local RESET button

that only can be accessed after breaker cover

removal.
