SELECTION GUIDE
Selecting a WLM7HU-250-3300 AC Photovoltaic MCCB
Specify the complete order code, circuit duty, installation conditions and required technical documents when requesting a WLM7HU-250-3300 quotation from W9 Group.
Specify the AC collection circuit
Provide the AC operating voltage, fault level and circuit arrangement. Confirm the selected voltage and capacity code together.
Match current to the release
Confirm the ordered current and time-current characteristics against conductor and load duty. Request any installation-dependent derating.
Choose the M or H capacity version
The original schedule separates M and H capacity columns. Request the complete order code and the applicable Icu/Ics row at the actual operating voltage.
Check panel integration
Request the matching mounting and terminal drawing, clearances, connection type and tightening instructions before panel manufacture.

BUYER FAQ
WLM7HU-250-3300 AC MCCB Configuration FAQs
Find answers about WLM7HU-250-3300 selection, configuration and ordering.
Is this photovoltaic MCCB an AC or DC breaker?
The target body and voltage table describe AC operation. Confirm a dedicated DC rating and pole diagram if a DC circuit is intended; the photovoltaic label does not establish that duty.
Which configuration is identified by the product summary?
The summary identifies 250A, 3P and 800V. The original frame schedule contains additional current choices, so confirm the offered current and release code.
Does the maximum series voltage apply to every version?
No single universal combination is established. Confirm the operating voltage and matching capacity code; use the exact row of the original AC schedule.
Are M and H breaking capacities interchangeable?
The original table provides separate M and H columns. Confirm Icu and Ics for the ordered version at the actual circuit voltage, rather than choosing a series maximum.
Can it mount on DIN rail?
The original mounting schedule does not mark DIN-rail mounting as available. Confirm the offered fixed or plug-in connection and the installation drawing for the exact unit.
Which trip settings should be specified?
Request the exact release functions, setting legend and time-current curves. A frame-current schedule is not an adjustment range for every trip-unit version.
What is needed for a WLM7HU-250-3300 quotation?
Send the required configuration, quantity, destination market and document requirements. Ask W9 Group to confirm price, minimum order quantity, samples and lead time for the selected configuration.
