Product: Dual power transfer isolation switch HGO84P40A Key benefits Automatic, fast transfer between mains and backup power to maintain continuous power supply for critical home devices. Fast response with switching time under 50 ms to minimize interruption. Designed for straightforward installation in Pz30 distribution boxes to improve transfer reliability in residential track TV setups. Robust construction for longterm performance: flameretardant housing and corrosionresistant components. What it does Automatically switches to backup power when the city mains supply is abnormal and switches back when mains are restored. Provides isolation between power sources to reduce risk of backfeed during transfer. Performance and operating parameters Coil operating range: normal operation from 85 percent to 110 percent of rated working voltage. Operation below this range may cause coil heating. Switching time: less than 50 ms. Contact material: allcopper with silver point contacts for good conductivity and reliable connection efficiency. Compatibility and application Model HGO84P40A is tailored for home track TV installations. Specifically compatible with Pz30 distribution box installations to improve transfer performance. Suitable for residential distribution panels where automatic transfer and isolation between two power sources is required. Physical and packing information Unit weight: 290 g. Bulk packing: outer box dimensions for 240 pieces: 45 x 24 x 33.3 cm. Net weight of packing (240 pieces): 19.9 kg. Typical use scenarios 1. Home track TV system: automatic transfer to backup power during mains interruption to keep televisions and media equipment running with minimal downtime. 2. Residential distribution box installation: fitted in Pz30 distribution boxes to provide reliable automatic switching and isolation between city power and backup supply. 3. Small residential or light commercial systems where compact, fast automatic transfer and isolation are required for essential circuits. Materials and build Housing: flameretardant material that is rugged and corrosionresistant. Contacts: allcopper silver point contacts for conductivity and effective connection. Notes for installation and operation Ensure coil supply stays within 85 percent to 110 percent of the rated voltage to avoid coil overheating. Confirm compatibility with the target distribution box model Pz30 before installation. Follow local electrical codes and standard installation practices when integrating into distribution panels.
