Siemens 3VA4120-6ED14-0AA0 Molded Case Circuit Breaker

Siemens 3VA4120-6ED14-0AA0 is a 1-pole molded‑case circuit breaker (MCCB) from the Sentron 3VA41 family, rated for 20 A and up to 600 V, and it comes with a TM210 thermal‑magnetic trip unit for both overload protection and fast short‑circuit action. This non‑interchangeable‑trip device uses load‑lug terminals and has an overload setting of In = 20 A with an instantaneous trip Ii = 15 × In, delivering robust protection for branch circuits and feeders in commercial or light industrial panels, with a short‑circuit interrupt rating up to 65 kA at 277 V. The unit carries UL frame designation and is designed for integration into Siemens protection schemes, enabling coordinated protection with other Siemens devices. With its compact 1P form factor and precise, factory‑set protection, it is well suited for applications where reliable, fast isolation of fault conditions is required in a single‑pole protective solution.
