Guía de selección
Selecting an AC Photovoltaic MCCB by Voltage, Poles and Fault Duty
Specify the AC/DC circuit duty, supply voltage, current, pole arrangement, breaking-capacity code and trip-unit configuration when you request a WLM7HU-400 quotation from W9 Group.
Specify the circuit side
State the AC inverter-output or distribution duty, supply voltage and pole arrangement.
Specify the current and trip unit
Reference WLM7HU-400 and ask for the exact operating current and trip-unit functions. Confirm whether the offered unit is a breaker or switch-disconnector.
Confirm fault duty
Provide prospective fault current and request Icu/Ics at the intended voltage, pole arrangement and capacity code.
Check panel fit
Use the catalog dimensions only for initial planning; request the installation drawing, terminals and clearances for the ordered device.

Preguntas frecuentes del comprador
WLM7HU-400 AC MCCB FAQs: Current, Trip Unit and Voltage Checks
Find answers about WLM7HU-400 selection, configuration and ordering.
What does WLM7HU-400 identify?
The catalog identifies the WLM7HU series with a 400 A designation. Confirm the fitted current rating, pole arrangement and complete order code.
Can I apply the highest series voltage to every pole arrangement?
Confirm the rated operational voltage and wiring drawing for the selected pole arrangement. A series voltage list does not establish every voltage/pole combination.
Which protection functions are included?
Request the actual trip-unit configuration and coordination curves. Confirm breaker versus switch-disconnector and any optional accessories in the quotation.
What is needed for a WLM7HU-400 quotation?
Envíe la configuración requerida, la cantidad, el mercado de destino y los requisitos documentales. Solicite a W9 Group que confirme el precio, la cantidad mínima de pedido, las muestras y el plazo de entrega para la configuración seleccionada.
What is this WLM7HU molded case circuit breaker used for?
The source identifies the WLM7HU series for its stated photovoltaic circuit duty, but exact breaker versus switch-disconnector and protection functions depend on configuration. Request the matched datasheet and trip-unit details.
How should I confirm the breaking capacity?
Provide prospective fault current and request Icu/Ics for the intended voltage, pole arrangement and capacity code; do not apply the series voltage list to every configuration.
