Frequently Asked Questions

What is the advantage of a self-healing capacitor?

The self-healing property allows the capacitor to automatically restore insulation after a dielectric breakdown caused by over-voltage, ensuring the unit continues to operate reliably without immediate failure.

How does the internal safety device protect the system?

The capacitor is equipped with internal fuses and discharge resistors. In the event of an internal fault, the fuse disconnects the power supply, while the resistor ensures residual voltage drops to safe levels quickly.

Does this capacitor require specific maintenance for oil leaks?

No, this product uses a half-solid soak material with a high melting point (>70°C). This design eliminates the risk of oil leakage, making it environmentally friendly and maintenance-free.

What is the maximum allowable voltage for this series?

The BSMJ series can handle a maximum allowable voltage of up to 110% of its rated voltage, providing a safety margin for fluctuating power conditions.

In what environments can these capacitors be used?

They are ideal for low-voltage electric networks where power factor correction is required to reduce energy loss and improve the quality of the voltage supply.

How fast does the capacitor discharge after being switched off?

According to the technical parameters, the residual voltage will drop to less than 50V within 3 minutes after the power supply is disconnected.
