Product FAQs
8 answersWhat circuit rating should I use when selecting the Siemens SHND6A120LSIG?
This is a 1200A, three-pole molded case circuit breaker for a three-phase circuit. Select it when the circuit design calls for that current rating and pole configuration.
Can this breaker be used on a 480VAC or 600VAC circuit?
It is rated for 480VAC and 600VAC circuits. Match the voltage rating to the circuit voltage, and use the interrupting rating associated with that voltage when evaluating available fault current.
How much available fault current can this breaker interrupt?
Its interrupting rating is 65kA at 480VAC and 50kA at 600VAC. The available fault current at the installation point must not exceed the interrupting rating for the circuit voltage.
What does the adjustable LSIG electronic trip do?
LSIG provides long-time, short-time, instantaneous and ground-fault protection through an adjustable electronic trip. These functions address sustained overloads, short circuits and ground faults. Choose trip settings to meet the circuit's protection and coordination requirements.
What conductor sizes can I terminate at the breaker?
The lug terminals accept conductor sizes from 250 kcmil to 500 kcmil. Select conductors within that range while also meeting the circuit's ampacity requirements.
Can I feed this breaker through its load-side terminals?
Yes. Its reverse-feed construction allows the incoming supply to connect at the load side, giving flexibility in the direction of the power feed.
What does the HACR rating mean for my application?
HACR refers to heating, air-conditioning and refrigeration applications. The HACR rating supports selection for circuits that require HACR-rated breaker protection.
Which approvals and breaker standard apply to this model?
The breaker has UL and CSA approvals and meets UL 489. UL 489 covers molded case circuit breakers used for branch-circuit protection, making this standard relevant when selecting the required type of circuit protection.
