Request DatasheetOverview
A complete final-circuit protection range from a single approved make, so discrimination between the MCB, the MCCB upstream and the incoming ACB actually holds when a fault occurs. Supplied with the accessories that installations really need — shunt trips, auxiliary contacts, under-voltage releases, rotary handles and terminal shrouds.
Technical specifications
| MCCB range | 16 A – 1600 A, 25 – 70 kA |
|---|---|
| MCB range | 0.5 A – 125 A, 10 kA |
| Tripping curves | B, C and D characteristic |
| RCCB sensitivity | 30 mA / 100 mA / 300 mA |
| Accessories | Shunt trip, aux contact, UV release |
| Standard | IS/IEC 60898 & IS/IEC 60947 |
Specifications are indicative. Final ratings are confirmed against your site conditions and the approved make.
Applications
- Final circuit and sub-distribution protection
- Earth-leakage protection in buildings
- Panel internal and control circuit protection
