Siemens 3VA4130-4ED34-0AA0 Molded Case Circuit Breaker

Its rated current is 30A. Select it when the circuit's load calculation and conductor-protection requirements call for a 30A breaker.

The rated voltage is 600VAC, with interrupting ratings of 25kAIC at 480Y/277VAC and 14kAIC at 600Y/347VAC. Compare available fault current with the interrupting rating at the applicable system voltage. The 600Y/347V rating applies to that wye system configuration.

No. Both the thermal and magnetic trip settings are fixed. The thermal-magnetic LI trip provides long-time overload protection and instantaneous short-circuit protection, so select it for applications that do not require adjustable trip settings.

The conductor range is 14-8 AWG copper or aluminum, and the load-side connection is a lug. Choose a conductor within that range that also meets the circuit's ampacity and installation requirements.

Yes. The reverse-feed feature allows incoming power to enter from either end of the breaker. This supports installations where the incoming conductor routing calls for the opposite feed direction.

HACR means heating, air conditioning and refrigeration. The rating is relevant when selecting circuit protection for those loads, alongside the required current, voltage and interrupting ratings.

The breaker is 5.1 in high, 3.0 in wide and 3.0 in deep. Use these dimensions to plan its physical footprint and depth, while accounting separately for conductor routing and termination space.

The operating temperature range is -25C to 70C. Evaluate the temperature where the breaker will operate, including heat generated inside the enclosure, when selecting the installation location.

The Siemens 3VA4130-4ED34-0AA0 has a three-phase rating and three poles. Use these ratings to check the circuit's phase count and the number of phase conductors requiring overcurrent protection.
