This document applies to Load-Shedding Equipment (LSE) for household and similar uses. The load-shedding function is used in energy management systems to optimize the overall use of electrical energy including production and storage. Load-shedding can be used for example for energy efficiency purposes as per IEC 60364-8-1. This document applies to LSE for operation under normal conditions: AC circuits with rated frequency of 50 or 60 Hz with a rated voltage not exceeding 440 V (between phases), a rated current not exceeding 125 A and a rated short circuit capacity not exceeding 25 000 A; or DC circuits 1). LSE are intended to control the energy supplied to one or more load, circuit or mesh when: defined conditions of time and current (power) are reached; a command by an external system is received. Note to entry : A LSE that monitors the loads based on time and power conditions is a LSE able to monitor voltage fluctuations from the network in addition to the current. Refer to definitions and relevant LSE characteristics for analogies. A LSE is intended to serve as: either as a single equipment having all the necessary means able to control the loads (e.g. the electrical energy management function is embedded in such an equipment); or a unit integrated into a more complex equipment or an independent equipment being part of an Electrical Energy Management System (EEMS); or an assembly of independent equipment forming a LSE (e.g. a LSE with external current sensors); or as a combination of the above points. LSE may have a wireless interface. Examples of LSE are given in Annex A. LSE is part of the fixed installation. LSE are intended for use in circuits with protection against electrical shock and over-current according to IEC 60364 series. NOTE 1 For example, fault protection (indirect contact protection) can be covered as follows: in TT systems, by an upstream RCBOs or RCCBs according to IEC 61008-1 and 61009-1; in a TN system, by an upstream over-current protective device. LSEs do not, by their nature, provide an isolation function nor the over-current protection. LSEs are normally installed by instructed persons (IEV 195-04-02) or skilled persons (IEV 195-04-01) and normally used by ordinary persons (IEV 195-04-03). 1 LSE for DC circuits are under consideration. This document contains all requirements necessary to ensure compliance with the operational characteristics required by type tests for LSEs based on single equipment or based on an assembly of independent equipments being part of a complete EEMS. These requirements apply for standard conditions of temperature and environment as given in 5.1. They are applicable to LSEs with a degree of protection of IP 20 intended for use in an environment with pollution degree 2. For LSE having a degree of protection higher than IP 20 according to IEC 60259, for use in locations where arduous environmental conditions prevail (e.g. excessive humidity, heat or cold or deposition of dust) and in hazardous locations (e.g. where explosions are liable of occur), special construction can be required. If other functions are included in LSE, these functions are covered by the relevant standards. LSEs can be provided with screwless terminals. LSEs covered by this document, with the exception of those rated 120 V or 120/240 V, are suitable for use in IT systems. This document does not intend to address communication aspects such as protocols, interoperability, data security and any other related aspects. Whenever needed, relevant standards can apply. The LSE shall not reduce the level of the integrity of the installation.
