- DC ISOLATORS 32A, 60A
- DC SURGE PROTECTION TO CLASS 1 OR CLASS 2 – for solar PV array or battery surge SPD
ALTERNATING CURRENT
- circuit breakers – SABS only
- 220VAC 1PH-2POLE/3POLE
- 400VAC 3PH – 3P/4POLE
- SURGE PROTECTION TO CLASS 1 OR CLASS 2 SPD
- MCB AND MCCB protection breakers all AMPS to 2400A
BEWARE OF UNCERTIFIED PROTECTION GEAR
BEWARE OF USING AC FOR DC PROTECTION as it is not the same!! (arc lengths , responsiveness and protection levels are different!!)
Danger of fire leading to potential safety or death as well as non-compliance electrical installation
