CNSX Vigi add-on
Addition of the Vigi add-on does not modify circuit-breaker characteristics:
| Rated Voltage | Model | Dimension（mm) | Weight（kg） |
| 220-440V 440-550V | CNSX、CNSV、CNS 100-250A 3P | 105*236*86 | 2.5 |
| CNSX、CNSV、CNS、CEZC 400-630A 3P | 135*355*110 | 8.8 | |
| CNSX、CNSV、CNS 100-250A 4P | 140*236*86 | 3.2 | |
| CNSX、CNSV、CNS、CEZC 400-630A 4P | 180*355*110 | 10.8 |
Vigi add-on may be equipped with an auxiliary contact (SDV) to remotely signal tripping due to an earth fault.
Use of 4-pole Vigi add-on with a 3-pole CNSX “In a 3-phase installation with an uninterrupted neutral, an accessory makes it possible to use a 4-pole Vigi add-on with connection of the neutral cable.”
“Vigi add-on are self-powered internally by the distribution-system voltage and therefore do not require any external source. They continue to function even when supplied by only two phases.”
