Full Description:
Built-In Safety: Advanced PTC Protection
The standout feature of the IMITOS WD-30 is its integrated PTC (Positive Temperature Coefficient) Protection. Standard mechanical doorbells can become major fire hazards if an outdoor doorbell switch gets physically stuck in the "on" position, causing the internal coils to overheat rapidly. The IMITOS WD-30 mitigates this risk entirely. The internal PTC protection mechanism acts as an automatic, resettable safety fuse. If an abnormal surge or a stuck switch causes the current to rise, the PTC component increases its electrical resistance to drastically minimize current flow, protecting the internal wiring from overheating, melting, or catching fire. Once the issue is resolved and the temperature drops, the PTC self-resets to its normal operating state without needing manual fuse replacements.
Engineered for Malaysian Homes
