That adjustable Ir range gives the panel builder flexibility to match the breaker to the actual continuous load without swapping the trip unit — useful when the connected load is slightly below the frame rating. The nut keeper kit included is a small but practical detail for DC Power OEM builds in China — it keeps the terminal hardware captive during assembly, saving a few minutes per panel.","metaTitle":"Siemens 3VA1112-4EF42-0AA0-ZD00 Circuit Breaker, 125A, 36kA","metaDescription":"Siemens 3VA1112-4EF42-0AA0-ZD00 IEC frame 160 circuit breaker, 4-pole, 125A, 36kA breaking capacity @ 415V.
