Indoor Grounding Switch

We are pleased to introduce SanGao Indoor Grounding Switch JN15A-12/31.5 indoor medium voltage AC grounding switch (sensorless), which is an advanced high-performance product.

SanGao Indoor Grounding Switch for Switchgear is a mechanical switch device used to protect circuit components. It can maintain a certain amount of current for a certain period of time in abnormal situations such as short circuits. Under normal circuit conditions, it does not carry any current. It will only start in abnormal situations.

Earthing Switch for Indoor Grounding is an essential device in every electrical installation, as it can protect technicians and switchgear in the event of abnormal current conditions, which is connected to the components of the switchgear to ensure the safety of electrical equipment and prevent further damage, such as fire or personal injury.

It has short circuit closing capability, which can protect other electrical equipment from potential damage, and can be seamlessly integrated with various medium voltage switchgear. In addition, it is also an important protective component in the maintenance process of high voltage electrical equipment.

Product Characteristics

●Dual safety functions

It has the capabilities of maintenance grounding and short-circuit closing. During equipment maintenance, it provides reliable grounding protection; when there is an incorrect power supply, it can forcibly close the short-circuit current, creating conditions for the upstream circuit breaker to trip, thereby protecting other equipment inside the cabinet.

●High standard compliance

The design and performance usually strictly follow GB1985 (domestic standard) and IEC 62271 (international standard), ensuring the safety and reliability of the product.

●Wide system adaptability

It is suitable for power systems with rated voltages of 3-12 kV and three-phase AC 50 Hz. It can be integrated with various metal enclosed switchgear to achieve "five prevention" interlocks.

●Stable mechanical and electrical performance

It adopts a spring energy storage rapid operation mechanism. Its closing speed is independent of the operator, ensuring rapid and reliable operation. It usually has a high rated short-time withstand current and rated peak withstand current.
