Product FAQs

7 answers
How do I select the current setting for the Siemens 3VA6712-6KQ31-2AA0?

This breaker is rated 1200A and has an adjustable trip range of 500-1200A. Choose a setting within that range appropriate for the circuit load and conductor protection requirements, rather than treating 1200A as a fixed trip setting.

Which system voltages can this breaker be used on?

The breaker is rated for 240VAC, 480VAC and 600VAC. Select it for the applicable system voltage and check the interrupting rating at that voltage.

How much available fault current can this breaker interrupt?

The interrupting ratings are 100kA at 240VAC, 65kA at 480VAC and 35kA at 600VAC. The available fault current at the installation point must not exceed the rating for the system voltage.

What protection functions does the LSIG electronic trip include?

LSIG includes long-time, short-time, instantaneous and ground-fault protection. These functions address sustained overcurrent, faults handled with a short delay, faults requiring immediate tripping and ground faults, allowing protection settings to be planned for the circuit.

What temperature range should I use when selecting the installation location?

The temperature rating is -25C to 70C. Use this range when evaluating the temperature conditions the breaker will experience at its installation location.

Does this breaker meet UL 489 requirements?

The breaker has UL approval and meets UL 489, the standard for molded case circuit breakers. This supports selection where a UL 489 molded case circuit breaker is required.

What does the pole count mean when selecting this breaker?

This breaker has three poles and a three-phase rating. Pole count determines how many circuit conductors the breaker can interrupt, so include it in your circuit protection selection.
