Here is the breakdown of its microsecond response process:\r\n<h3 style=\"color: #333333;\">Phase 1: Normal Operating State (High Impedance)<\/h3>\r\nUnder continuous operating voltage (e.g., 230V\/400V AC), the Metal Oxide Varistor exhibits extremely high electrical resistance (several megohms). To the electrical network, the SPD acts as an open circuit, drawing virtually zero leakage current.\r\n<h3 style=\"color: #333333;\">Phase 2: Transient Overvoltage Trigger (Clamping Phase)<\/h3>\r\nWhen a transient voltage spike hits the line (exceeding the Maximum Continuous Operating Voltage, U<sub>c<\/sub>), the MOV instantly transitions within nanoseconds (&lt;25 ns) from high impedance to extremely low impedance (a few ohms).\r\n<h3 style=\"color: #333333;\">Phase 3: Energy Diverting &amp; Voltage Clamping<\/h3>\r\nThe 20kA SPD creates a safe low-resistance path to the ground. The massive surge current (up to 20kA) is safely diverted away from your sensitive equipment to the earth ground system. Simultaneously, the residual voltage across the protected line is clamped down to a safe level\u2014known as the <strong>Voltage Protection Level (U<sub>p<\/sub>)<\/strong>.\r\n<h3 style=\"color: #333333;\">Phase 4: Instant Reset<\/h3>\r\nOnce the surge energy dissipates (usually within microseconds), the MOV automatically returns to its initial high-impedance state, restoring normal line operation without causing breaker trips or system downtime.\r\n<div style=\"background-color: #f4f9f9; border: 1px solid #009292; padding: 20px; border-radius: 6px; margin: 25px 0;\">\r\n<h3 style=\"color: #009292; margin-top: 0;\">Tool: Quick SPD Sizing Assessment<\/h3>\r\n<p style=\"font-size: 14px; margin-bottom: 15px;\">Are you selecting an SPD for a Main Panel or Sub-Panel?

For main service entrances exposed to direct lightning, Type 1 SPDs with impulse current (I<sub>imp<\/sub>) ratings are recommended.\r\n\r\n<strong>Q3: How long does a 20kA Surge Protection Device last?<\/strong>\r\nA: Lifespan depends on grid stability and surge frequency. Under normal conditions, quality MOV-based SPDs last 5 to 10+ years. The visual status window on Britec SPDs indicates when replacement is required.\r\n\r\n<strong>Q4: How do I know if my 20kA SPD module needs to be replaced?<\/strong>\r\nA: Britec 20kA SPDs feature a mechanical status indicator. Green indicates normal working condition; Red indicates the internal thermal disconnector has opened, requiring pluggable module replacement.\r\n\r\n<strong>Q5: Can a 20kA SPD protect against direct lightning strikes?<\/strong>\r\nA: A Type 2 20kA SPD handles indirect lightning surges and grid switching spikes. Direct lightning strikes require Type 1 spark-gap or heavy-duty combination SPDs installed at the building entrance.\r\n\r\n<strong>Q6: What is the typical Clamping Voltage (U<sub>p<\/sub>) of a 20kA SPD?<\/strong>\r\nA: Typical U<sub>p<\/sub> values for a 20kA 230V AC SPD range between 1.2kV and 1.5kV, safely below the withstand voltage of standard commercial equipment.\r\n\r\n<strong>Q7: Does a 20kA SPD require an upstream backup circuit breaker or fuse?<\/strong>\r\nA: Yes. A dedicated backup miniature circuit breaker (MCB) or backup fuse prevents short-circuit risks in the rare event of an unisolated SPD failure.\r\n\r\n<strong>Q8: Can 20kA SPDs be used in DC solar PV applications?<\/strong>\r\nA: AC 20kA SPDs cannot be used on DC circuits. However, Britec offers specially designed 20kA DC PV Surge Protective Devices rated for up to 1000V\/1500V DC installations.\r\n\r\n<strong>Q9: How do you mount a 20kA SPD in an electrical panel?<\/strong>\r\nA: Britec 20kA Type 2 SPDs feature standard 35mm DIN-rail mounting, allowing effortless snap-on installation alongside standard circuit breakers.\r\n\r\n<strong>Q10: Can Britec Electric customize 20kA SPDs for OEM projects?<\/strong>\r\nA: Yes, Britec Electric provides full OEM\/ODM manufacturing, including custom housing colors, branding, voltage configurations, and technical certifications.\r\n\r\n<hr style=\"border: 0; border-top: 1px solid #cccccc; margin: 30px 0;\" \/>\r\n\r\n<h3 style=\"color: #009292;\">Related Resources<\/h3>\r\n<ul>\r\n \t<li><a href=\"https:\/\/www.britecelectric.com\/tr\/\" target=\"_blank\" rel=\"noopener\">Explore Britec Electric Full SPD Product Catalog<\/a><\/li>\r\n \t<li><a href=\"https:\/\/www.britecelectric.com\/tr\/contact-us\/\" target=\"_blank\" rel=\"noopener\">Contact Britec Technical Support for Project Consultations<\/a><\/li>\r\n<\/ul>","protected":false},"featured_media":2556,"parent":0,"menu_order":56,"template":"","meta":{"_acf_changed":false},"blog_category":[9],"class_list":["post-2555","blog","type-blog","status-publish","has-post-thumbnail","hentry","blog_category-industry-news"],"acf":{"des":"Discover how 20kA Surge Protection Devices (SPDs) shield industrial & commercial power systems from voltage spikes.
