SELECTION GUIDE

Selecting an 800A Earth Leakage MCCB by Sensitivity and Poles

Specify the selected current, poles, leakage sensitivity and delay, waveform requirement, voltage, fault duty and alarm mode when requesting a WLM6LY-800 quotation from W9 Group.

01

Choose the ordered current

The 800 A page lists 500, 630, 700, 800 A. Confirm the selected current and full model suffix, including the pole arrangement.

02

Specify leakage protection

Provide the required sensitivity, waveform response and delay. Confirm the actual available settings; residual-current making capacity is not the sensitivity setting.

03

Check voltage and fault duty

Use the selected configuration’s operational-voltage and breaking-capacity data. Confirm the capacity code and do not substitute insulation voltage for operating voltage.

04

Define alarm, mounting and wiring

Confirm tripping versus alarm-only behavior, mounting form, neutral routing and the connection drawing. Request the required test and commissioning instructions.

Before specifying WLM6LY-800: Confirm current, poles, residual-current sensitivity and delay, alarm / trip mode, operating voltage and voltage-specific fault ratings. The source mixes generic RCCB prose and configuration data; do not treat the prose as a complete order specification.

BUYER FAQ

WLM6LY-800 Earth Leakage MCCB FAQs: Sensitivity, Alarm and Fault Duty

Find answers about WLM6LY-800 selection, configuration and ordering.

Which current choices are listed for WLM6LY-800?

The summary identifies 800 A. The frame schedule lists 500, 630, 700, 800 A. Confirm the selected current and complete order code; the schedule is not a guaranteed adjustment range.

Is this an RCCB without overcurrent protection?

The target table describes a molded-case device with overcurrent and leakage releases. Confirm the complete protection functions in the matching datasheet; generic RCCB text is insufficient to classify the ordered unit.

What leakage sensitivity can I order?

A definitive sensitivity schedule is not established by the available page. State your required residual-current pickup and delay, then confirm the available combination with W9 Group.

Does the listed residual-current type cover every waveform?

The table lists AC residual-current response. Confirm the expected leakage waveform and required device type; do not assume support for other waveforms from the electronic release description.

Can the breaker signal leakage without tripping?

A leakage-alarm non-tripping function is marked as an option. Confirm whether it is available, which mode is supplied and how the alarm is wired for the exact order code.

How should I select voltage and breaking capacity?

Request the operational-voltage and Icu / Ics data for the pole arrangement and capacity code. Confirm discrepancies between the summary and table before installation; no universal fault rating is assigned here.

What is needed for a WLM6LY-800 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.
