FAQs
MDLPV3600W uses the MDL frame designed for complete breaker assemblies in photovoltaic protection schemes. When installing, verify enclosure clearances for an 8.25 in cube footprint and ensure panel bus connections align with lugs or bus bars compatible with theไม่มี terminals configuration. The no-terminals design simplifies field fitting, reducing installation time and potential miswiring in DC PV applications.
The MDLPV3600W is rated for 600 A with a maximum of 1000 Vdc. It provides an interrupt rating of 7.5 kAIC at 1000 Vdc and uses a three-pole MDL frame with fixed thermal and magnetic trip (T186). These specifications support high-current PV protection, rapid fault clearance, and compatibility with PVGuard configurations in DC distribution networks.
This device is specified as a three-pole breaker, making it suitable for three-phase PV DC protection schemes commonly found in PV array combiner boxes and DC distribution panels. Its MDL frame and 1000 Vdc rating enable reliable protection across all three conductors, ensuring balanced protection and simplified wiring in three-phase PV installations.
The MDLPV3600W carries UL Listed certification, a cornerstone for electrical safety compliance in North America. This certification supports regulatory acceptance for PV protection devices in utility and commercial solar installations. When designing for broader markets, verify regional requirements for additional marks such as CE or IP ratings, but for US-based PV systems, UL Listed provides strong alignment with industry standards.
Maintenance is typically low due to solid-state trip mechanisms and robust construction. The MDLPV3600W’s fixed thermal/magnetic trips reduce nuisance tripping and help maintain system uptime. ROI benefits stem from reliable PV protection, reduced repair costs after faults, and faster installation with the MDL frame’s compatibility, which lowers labor costs during retrofits and new-build PV projects.
