Eighteen exact frequency records, seven content-distinct product images and nine dimension paths representing seven content-distinct drawings.

03

Confirmation

Certification scope, North American electrical suitability and final duty selection require written confirmation before quotation.

KBZE FAQ

Automatic control and source boundaries.

Is KBZE a separate published product entry from KBZ?

Yes. The published data Contents assigns KBZE its own pages 25-28, so this page is separate from the KBZ pages 21-24.

How does KBZE control water level?

An adjustable electric probe controls operation. Published data states that the pump stops within 60 seconds after the level falls below the probe and starts again when water reaches it.

What built-in protection does KBZE provide?

Published data lists reverse-phase, open-phase, impeller-jam, overload, abnormal-voltage and high-temperature responses, including automatic recovery where specified.

Are both published frequencies represented in the current catalog?

Yes. All nine exact KBZE codes have one current 50 Hz record and one current 60 Hz record.

Why do some current maximum values differ slightly from published data?

The current catalog retains decimal-resolved endpoints while published data tables use rounded values. Both sources are shown separately and should be confirmed against the approved curve before quotation.
