3VA5150-6ED31-1AA0 SIEMENS

The 3VA5150-6ED31-1AA0 is a robust 3-pole circuit breaker from Siemens, designed for reliable line protection in industrial and commercial applications. This UL 489 certified breaker falls under frame size 125 and boasts a high breaking capacity class H, capable of interrupting fault currents up to 65kA at 480V. Equipped with a TM210 trip unit, it offers fixed thermal-magnetic (FTFM) protection, ensuring precise and dependable circuit control. The breaker's rated current (In) is 50A, with overload protection (Ir) fixed at 50A to prevent sustained overcurrent conditions. Its short-circuit protection (Ii) is set at 10 times the rated current (10 x In), providing rapid response to high-level fault currents. This model is specifically designed and approved for naval applications (SB), demonstrating its resilience and suitability for demanding environments. It maintains optimal performance even at elevated ambient temperatures of up to 50 degrees Celsius. Note that this particular model is supplied without connection terminals, allowing for flexible installation options based on specific application requirements. This circuit breaker provides superior protection and reliability.
