Residual Current Device

Residual Current Device

Details
A residual current device (RCD) detects leakage current to earth and trips the circuit quickly to protect people against electric shock and to reduce fire risk from earth faults. It monitors the vector sum of the line and neutral currents and operates when the residual current exceeds the rated sensitivity, typically 30 mA for personal protection. It can be supplied as a standalone RCD or combined with overcurrent protection as an RCBO.

Residual Current Device

Product Description

A residual current device (RCD) detects leakage current to earth and trips the circuit quickly to protect people against electric shock and to reduce fire risk from earth faults. It monitors the vector sum of the line and neutral currents and operates when the residual current exceeds the rated sensitivity, typically 30 mA for personal protection. It can be supplied as a standalone RCD or combined with overcurrent protection as an RCBO.


RCD performance depends on precise tripping parameters, so we can configure rated sensitivity, poles and breaking capacity to the application, with OEM branding. Batch production with 100% inspection verifies tripping consistency before delivery, which is important for buyers supplying safety-critical products.

Applications

 
 

Residential final circuits

Protects socket and lighting circuits against earth leakage where people are at risk.

 
 
 

Wet and outdoor areas

Provides additional protection for bathrooms, kitchens and outdoor circuits where shock risk is higher.

 
 
 

Construction and temporary supplies

Protects temporary site distribution from earth faults and improves overall electrical safety.

 

 

Customization

We customize the residual current device in rated residual current, poles, type (RCD or RCBO) and customer branding, based on the application specification. OEM production is supported.

 

Packaging & Transportation

Devices are packed in export cartons with internal protection, and bulk orders are additionally packed in seaworthy wooden cases, after 100% inspection before packing. Supported trade terms: FOB to a designated Chinese port and EXW.

 

FAQ

Q: Can you supply this as an RCBO with overcurrent protection?

A: Yes. We can supply both RCD and RCBO versions according to your specification.

Q: How long does sample development take?

A: Sample development generally takes about one week depending on the technical specification.

Q: Do you perform 100% inspection before packing?

A: Yes, 100% full inspection before packing is mandatory for all our products.
