Surge protection devices (SPDs) protect LV electrical installations and sensitive equipment from transient overvoltages caused by lightning strikes, switching surges and grid disturbances. Micron Electric UK's DIN-rail mounted SPD range covers Class I (Type 1), Class II (Type 2) and Class III (Type 3) protection — meeting the requirements of IEC 61643-11 and DEWA Distribution Standards for surge protection in UAE buildings and facilities.
| Class | IEC Type | Location | Impulse Current | Protects Against |
|---|---|---|---|---|
| Class I | Type 1 | Main distribution board (MDB) | Up to 100kA (10/350μs) | Direct lightning strike on building or supply |
| Class II | Type 2 | Sub-distribution board (SDB) | Up to 40kA (8/20μs) | Induced surges from nearby lightning, switching |
| Class III | Type 3 | At equipment (socket, panel) | Up to 10kA (8/20μs) | Residual surges reaching sensitive equipment |
| Class I+II | Type 1+2 | MDB (combined protection) | Up to 100kA | Both direct and induced surges — single device |
DEWA's latest distribution standards and the UAE's adoption of IEC 60364-5-53 require surge protection in all new LV installations. Buildings without SPDs risk equipment damage, fire and insurance liability. Micron Electric UK SPDs are pre-approved for use in DEWA-compliant LV boards across Dubai. Noor Al Bawadi, the authorized UAE distributor, stocks the full SPD range in Sharjah for immediate delivery to Dubai, Abu Dhabi and across the UAE.
