Full Description:
Key Features & Technical Benefits
- Double Pole (DP) Isolation: Unlike standard single-pole switches that only break the Live (L) wire, this double-pole mechanism simultaneously cuts off both Live (L) and Neutral (N) wires. This complete circuit disconnection prevents residual current leakage, protecting your appliances from electrical surges and significantly reducing the risk of electric shocks during maintenance or off-state periods.
- Integrated Red Neon Power Indicator: The built-in red neon indicator illuminates whenever the switch is toggled ON. This visual cue provides instant visibility from a distance, allowing homeowners to confirm whether energy-intensive appliances like water heaters or air conditioners are running.
- Heavy-Duty 20A 250V Rating: Rated specifically for 20 Ampere alternating current at 250V AC, the switch easily accommodates appliances up to 4000W to 4500W. This makes it ideal for continuous operations without risk of overheating or melting switch terminals.
- Standard 3x3 Module Sizing: Designed with universal 85mm x 85mm dimensions, the switch fits into standard Malaysian 3"x3" concealed or surface PVC pattress boxes for hassle-free installation during renovations or wiring upgrades.
Appliance Compatibility & Ideal Use Cases
- Storage & Instant Water Heaters: Fully supports single-point and multi-point water heater units commonly installed in Malaysian bathrooms.
- Air Conditioners (Wall-Mounted Split Units): Built to manage high startup current surges for 1.0 HP, 1.5 HP, 2.0 HP, and up to 2.5 HP air conditioning units.
- Heavy Commercial Equipment: Suitable for high-wattage kitchen appliances, industrial ventilation fans, high-load pumps, and dedicated power circuits.
