How do voltage stabilizers handle overloads?

Voltage stabilizers handle overloads through protective mechanisms designed to prevent damage to both the stabilizer and the connected appliances. Here’s how they typically do it:

1. Overload Protection Circuit

Most modern stabilizers include a built-in overload protection feature. When the connected load exceeds the rated capacity:

• The stabilizer will shut off automatically to prevent overheating or damage.
• Some models use a relay or circuit breaker to disconnect the output.
• Others might issue a warning beep or light before cutting off.

2. Thermal Overload Protection

If too much current flows for an extended time, internal components can overheat. Thermal protection:

• Uses a thermistor or thermal fuse to detect overheating.
• Automatically disconnects the output if the internal temperature exceeds a safe threshold.

3. Manual or Auto Reset

Depending on the model:

• Some stabilizers have a manual reset button you must press after an overload trip.
• Others automatically restart once the overload condition clears or the temperature drops.

4. Fuses or Circuit Breakers

Older or simpler models may rely on fuses or miniature circuit breakers (MCBs) that trip or blow when overloaded.

So in short: stabilizers protect themselves and connected devices by cutting off power in an overload situation, using a combination of sensors, relays, and breakers.
