Product FAQs
8 answersWhat does the 1000A rating mean when selecting this breaker?
The Siemens 3VA5710-5EC31-0AA0 has a rated current of 1000A. Use that rating when evaluating circuit load requirements and coordinating breaker selection with conductor protection.
How do I select this breaker for the circuit voltage and available fault current?
The interrupting ratings are 85kA at 240VAC, 35kA at 480VAC and 25kA at 600VAC. Select the rating corresponding to the circuit voltage and verify that it is at least equal to the available fault current at the installation point.
What protection does the thermal-magnetic LI trip provide, and what can I adjust?
The LI trip provides long-time overload protection and instantaneous short-circuit protection. The thermal portion is fixed, while the magnetic portion is adjustable, allowing the instantaneous pickup to be coordinated with circuit requirements.
What should I plan for mounting and conductor termination?
This breaker uses unit mounting and lug terminals. Plan for individual breaker mounting and lug-based conductor connections, with proper conductor preparation and terminal tightening during installation.
Which standards and approvals should I consider for project requirements?
The breaker meets UL 489 and IEC 60947-2, with CE, CSA, UL and VDE approvals. Use these when checking whether the breaker meets the project's required circuit breaker standards and approval criteria.
What does the HACR rating mean for HVAC circuit selection?
HACR means heating, air conditioning and refrigeration. This rating is relevant when selecting circuit protection for HVAC equipment that requires a HACR-rated breaker.
How should I use the -25C to 70C temperature rating?
Consider the -25C to 70C temperature rating when evaluating the installation's thermal environment. Check expected temperatures at the breaker location, including heat generated by surrounding equipment.
What does the three-pole configuration mean for interrupting a three-phase circuit?
The Siemens 3VA5710-5EC31-0AA0 has one pole for each phase conductor in a three-phase circuit. The three-pole arrangement allows the phase conductors to be interrupted together.
