Product FAQs
7 answersHow should I use the 400A rating when selecting the Siemens 3VA6340-7JP31-0AA0?
The 400A rated current is a selection point for matching the breaker to the circuit's load and conductor-protection requirements. Evaluate the adjustable trip settings separately when determining how the breaker will protect the circuit.
How much available fault current can this breaker interrupt?
The UL 489 interrupting ratings are 200kA at 240VAC, 100kA at 480VAC, and 35kA at 600VAC. Select the rating that corresponds to the circuit voltage and ensure it is at least equal to the available fault current at the installation point.
What protection functions does the LSI trip include?
LSI means long-time, short-time and instantaneous protection. Long-time protection addresses sustained overloads, while short-time and instantaneous functions address higher-current faults with delayed and immediate tripping, respectively. Use these functions when evaluating the circuit's protection requirements.
When should I choose this 3-pole breaker?
This is a 3-pole breaker for 3-phase circuits. Choose it when the circuit requires overcurrent protection on three phase conductors.
What does fixed mounting mean for installation and service?
Fixed mounting means the breaker is secured in place rather than installed as a withdrawable unit. Plan installation and service access around its fixed position.
What dimensions should I account for in the equipment layout?
The breaker measures 9.8 in high, 5.4 in wide and 5.4 in deep. Use these body dimensions when planning the layout, while also allowing space for conductor routing, termination work and service access.
Can I adjust the electronic trip settings?
Yes. The adjustable electronic trip lets you configure the protection response rather than use a fixed trip response. Choose this feature when your circuit design calls for adjustable protection settings.
