IEC TS 63053:2017(E) provides general minimum requirements, recommendations and information for the drafting and testing procedures of standards for residual current operated protective devices, 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.

Overview

IEC TS 63053:2017 is a Technical Specification that defines general minimum requirements, recommendations and testing guidance for residual current operated protective devices (DC‑RCDs) intended for use in DC systems with a rated voltage up to 400 V DC and a rated current up to 125 A. The document is aimed at helping national and product standards drafters and test laboratories to specify and verify safe, reliable DC‑RCD operation in photovoltaic, industrial and battery‑based DC installations.

Key topics and technical requirements

The specification covers the full lifecycle of DC‑RCD standardization and testing, including:

Scope and classification: device types based on installation, adjustable residual operating current, time‑delay behavior, mounting and terminal types, number of poles, instantaneous tripping and I²t characteristics.

Rated quantities and characteristics: rated voltages, rated direct current, making/breaking capacities, residual operating and non‑operating currents, conditional short‑circuit currents and preferred/standard values.

Construction and safety: mechanical design, clearance/creepage, terminals, protection against electric shock, dielectric strength and temperature‑rise limits.

Operating performance: defined trip behavior for steady, sudden and high residual currents (including tests for I∆n and I∆no), time‑delay categories, and coordination with short‑circuit protective devices (SCPDs).

Robustness and EMC: mechanical/electrical endurance, short‑circuit performance, resistance to shock, heat, fire, and electromagnetic compatibility (including ripple immunity). Specific surge tests include the 0.5 μs/100 kHz ring‑wave test and 8/20 μs surge current tests.

Test program and preparation: recommended test circuits, short‑circuit and inrush current tests, verification of trip‑free mechanisms, ageing of electronic components and climatic/reliability tests (e.g., tests at 40 °C).

Practical applications and users

IEC TS 63053 is practical for anyone involved in the design, manufacture, testing, certification or regulation of DC safety systems, including:

Manufacturers of DC‑RCDs and DC switchgear

Test laboratories and certification bodies preparing product standards and type‑approval tests

System integrators and designers of photovoltaic (PV), energy storage and electric vehicle charging installations

Regulatory bodies and standards committees drafting national or product standards for DC protective devices

By using IEC TS 63053, stakeholders can ensure consistent safety performance, interoperability and clearer requirements for DC residual current protection.
