What is PD IEC/TS 63053‒ Protective devices for DC systems about?
PD IEC/TS 63053 is an international standard that covers guidelines for the protective devices for DC systems.
PD IEC/TS 63053 provides general minimum requirements, recommendations, and information for the drafting and testing procedures of standards, for residual current operated protective devices. They are intended to be used in DC systems having a rated voltage not exceeding 400 V DC and a rated current not exceeding 125 A, hereafter referred to as DC-RCDs.
PD IEC/TS 63053 can also be used as a guide for DC-RCDs with voltages up to 1500 V DC.
PD IEC/TS 63053 is primarily intended to be used as a reference for drafting product safety standards for DC-RCDs.
Note: PD IEC/TS 63053 applies to a device:
- Which detects a residual current
- Compares it to a reference value
- Opens the contacts or poles when the residual current exceeds this reference value
Who is PD IEC/TS 63053‒ Protective devices for DC systems for?
PD IEC/TS 63053 on protective devices for DC systems is useful for:
- Manufacturers and suppliers of DC-RCDs
- Dealers and distributors of DC-RCDs
- Designers of DC-RCDs
- Test/ service providers for DC-RCDs
Why should you use PD IEC/TS 63053‒ Protective devices for DC systems?
DC systems are used for applications such as photovoltaic installations, data centres and telecom centres, and electric vehicle charging systems.
PD IEC/TS 63053 defines the operating characteristics for residual current operated protective devices for DC systems. It highlights the advantages of residual current devices for DC systems, to provide fault protection and protection against direct contact.
PD IEC/TS 63053 gives you technicalities for the various test methods, to ensure the high efficiency, reliability, and endurance of the DC-RCDs, as it contributes to providing protection against electric shock downstream of the device in DC networks.
PD IEC/TS 63053 proves to be very helpful to technical committees that are in the preparation of standards for residual current devices. It fulfils the requirement for the reference document for residual current devices intended to be used in DC supply systems is necessary.
