Mainline Protector
Villas, Schools, Hospitals & Commercial

Why MCBs Aren't Enough
- • MCB / fuse only trips after a short circuit occurs
- • By then, electronics may already be damaged
- • Delayed reaction can lead to fire incidents
Common External Causes
- • Loose wiring & neutral open / breakage
- • Transformer blast or fault
- • Wiring mistakes during maintenance or road digging
- • Birds or animals stuck between electrical wires
Our Protection
- • Sustains 440V surges for 7+ days continuously
- • Instant spike & surge cut-off
- • Prevention is better than protection
