描述：MAINS-PLUGTRAB? Pluggable two-pole modular lightning surge protector MAINS-PLUGTRAB is a slim design surge protector designed to protect the low voltage single-phase power supply of very sensitive equipment. It quenches over voltage as a result of inductive or capacitive connections. Its pluggable design allows for easy maintenance (surge protector plug combined with a base for electrical connection). Disconnection feature provides continuity of electrical power supply. Features a mechanical indicator which provides a status (operational or out of order) at all times and changeover contacts for alarm reports. Connects in series directly upstream of the device that will be protected, and is mounted on a symmetric profile. Protection class: | III ---|--- Rated voltage Un: | 230 V / 400 Vac Current rating In: | 20 A Max. permanent rated voltage Uc: | 250 Vac Max. discharge surge current Imax (8/20 μs): | 6.5 kA Rated discharge surge current In (8/20 μs): | 2.5 kA Protection level (Up): | 2.2 kV Protection level Up for 5 kA: | 1.2 kV Number of 17.5 mm pitch | 1 Footprint (L x H x thickness): | 18 x 97 x 66 mm Max. connection (rigid / flexible): | 2.5 / 4 mm2 Operating temperature: | \- 25 °C → + 85 °C Protection level: | IP 20 ### 電涌保護(hù)設(shè)備，SPD（DIN 導(dǎo)軌） 電壓浪涌經(jīng)常被稱為峰值或瞬態(tài)過壓，它通常由開關(guān)熒光燈、熔絲燒斷或附近的雷電活動造成。 最壞的電壓浪涌通常由雷電造成，電壓最高可達(dá) 6000V，且電流浪涌最高可超過 3000A。 由雷擊導(dǎo)致的電壓和電流浪涌最大值取決于建筑物布線系統(tǒng)內(nèi)的位置。 BS7671：2011 年第一次修正版，第 443 和 534 部分涵蓋風(fēng)險評估，并提供電子設(shè)備保護(hù)指導(dǎo)，供安裝工程師遵循。 BSEN 62305 標(biāo)準(zhǔn)系列可提供最全面的雷電和浪涌保護(hù)信息。
