FAQs
PV-355A-3L-15 is designed for straightforward integration with the SD3L-S-PV XL base. Ensure correct blade connections, align with the 3L fuse footprint, and verify top fuse status indicator visibility during commissioning. The unit measures 217 mm in depth, 82 mm in height, and 94 mm in width, which informs enclosure and clearance planning for outdoor UV-resistant environments.
With a 355 A amperage rating and a 1500 Vdc voltage rating, PV-355A-3L-15 supports large PV strings while maintaining rapid fault clearance. The 100 kAIC interrupt rating and pre-arc I2T of 44000 provide predictable performance, enabling reliable selective protection and minimizing arc energy in high-energy fault scenarios.
PV-355A-3L-15 is UL Listed and CSA Certified, with IEC 60269 compliance and CE RoHS marking. This combination ensures global regulatory alignment, facilitating cross-border project deployment and reducing the burden of multiple certification cycles for solar installations.
The top fuse status indicator provides immediate visual confirmation of fuse health, speeding fault localization during maintenance and reducing diagnostic time. This feature is especially valuable in outdoor or remote solar sites where quick status checks minimize downtime and support proactive replacement strategies.
Confirm compatibility with SD3L-S-PV XL fuse bases and verify the 3L fuse size matches the enclosure and mounting provisions. Check the physical footprint (217 mm depth, 82 mm height, 94 mm width) and ensure the enclosure allows proper heat dissipation given the 84 W watt loss. This ensures reliable operation and easy integration with existing protection schemes.
