Compliance with the following is acceptable for use as a ponent of an end product. 這些要求 適用 于 使用在 支路已有或不需要過載保護(hù) 的 電器或其他電力設(shè)施 上的具有 過載 、 過壓或欠壓保護(hù) 功能的輔助保護(hù)器 。終端產(chǎn)品的部件亦需遵從下述要求。 The acceptability of a protector in any particular application depends upon its ability to be used continuously under the conditions that prevail in actual service. Accordingly, for a particular application a protector may be affected by the requirements for the equipment it is used in, and it may be necessary to additionally evaluate features or performance characteristics that are not specified in this standard. 任意特定應(yīng)用下的保護(hù)器 的 可接受性取決于其 實(shí)際 使用狀況下持續(xù)工作 的能力 。因此，在某一特別應(yīng)用中，保護(hù)器可能受其外部設(shè)備的影響，并 可能 有必要對(duì)本標(biāo)準(zhǔn)未列明的特性進(jìn)行額外評(píng)估。 This standard also covers accessory devices that may be installed in or on the protector to perform a secondary function. Examples of accessories are alarm and auxiliary switches. 本標(biāo)準(zhǔn) 也 涵蓋安裝在保護(hù)器內(nèi)外，實(shí)現(xiàn)附屬功能的附件裝置，如警報(bào)和輔助開關(guān)。 Devices which ensure a manual restart due to the plete loss of voltage are covered by the Standard for S
