Product: 1pcs SPD 60100KA 1P Surge Arrester Protection Device Electric House Surge Protector D 420V AC Overview A singlepole surge protection device designed for residential electrical systems. Intended to reduce the effect of transient overvoltage events by diverting surge current away from connected equipment. Compact 1pcs unit with a D classification and a rated operating voltage of approximately 420V AC. Key benefits Protects connected equipment from transient voltage spikes by diverting surge current away from sensitive devices. surge capacity rated 60100KA supports strong transient events while limiting damage to downstream equipment. Singlepole 1P format simplifies integration into singlephase domestic distribution boards and live conductor protection. Straightforward replacement or addition to existing protection arrangements without changing wholepanel layouts. Dclass designation suitable for handling energy, slowfront surges commonly associated with indirect lightning and switching events. Main features and attributes Function: Surge arrester for transient overvoltage protection in electric house installations. Surge current capacity: Rated 60100KA (kiloamperes) for handling large surge events. Poles: 1P singlepole configuration for live conductor protection in singlephase systems. Rated voltage: Approximately 420V AC, suitable for residential supply systems up to that voltage. Quantity: 1pcs unit supplied for singlepoint protection needs. Design focus: Compact singlepole form factor for ease of installation and minimal panel space usage. Compatibility and use Compatible with singlephase residential electrical distribution panels and supply circuits with nominal voltages near 420V AC. Suitable as a dedicated protection device for circuits supplying sensitive household electronics and appliances. Can be combined with upstream or downstream protective devices as part of a layered surge protection approach. Performance notes Designed to conduct surge currents within the 60100KA rating during transient events to reduce overvoltage stress on connected equipment. Singlepole design targets protection of the live conductor; grounding and earthing arrangements should meet local electrical codes to ensure effective operation. Practical applications Home electronics protection: Install at the distribution board to help protect televisions, routers, computers, and home entertainment systems from voltage spikes. Workshop or small business circuits: Protect singlephase power circuits feeding tools and control electronics from switching surges. Backup power or inverter input protection: Use on singlephase circuits near inverters or backup supplies to help reduce surge exposure to power conversion equipment. Installation and operational considerations Designed for installation by qualified electricians familiar with local wiring regulations and grounding practices. Intended for use in conjunction with proper earthing to ensure effective surge diversion. Check system voltage compatibility and placement within the distribution board before installation. What this product is for A focused solution for reducing the impact of transient overvoltage events on singlephase residential circuits, offering a compact singlepole option with a surge current rating of 60100KA and a rated operating voltage of approximately 420V AC.
