Siemens 3VA 3VA4150-4ED34-0AA0 Circuit Breaker

Siemens 3VA4150-4ED34-0AA0 is a three-pole Sentron molded‑case circuit breaker rated for 50 A with a 25 kA short‑circuit rating at 480 V, designed to protect feeders in distribution panels. Built on the UL 125 frame (3VA4) and configured for TM210/FTFM use, it provides reliable overload and instantaneous protection with fixed overload setting In = 50 A and a fixed instantaneous setting Ir = 50 A, plus an instantaneous pickup Ii = 10 × In. The device uses standard terminal connections (klemmenaansluiting) for secure wiring and is commonly employed in commercial and light industrial electrical installations to guard circuits feeding motors, transformers, and other loads. Its compact, three‑pole form factor suits panelboards and switchgear where solid, predictable trip characteristics and coordination with upstream protection are required.
