3VA5191-1MH31-0AA0 SIEMENS

The 3VA5191-1MH31-0AA0 is a robust 3-pole circuit breaker from Siemens, designed for starter protection applications within UL frame 125 systems. This circuit breaker utilizes a TM120M trip unit, configured for AM (Starter Protection) functionality. It has a rated current (In) of 10A, making it suitable for protecting circuits with relatively low current demands. Notably, this model does not incorporate overload protection, focusing solely on short-circuit protection. The short-circuit protection (Ii) is adjustable within a range of 5 to 12 times the rated current (In), allowing for customization based on specific application requirements. This adjustability ensures rapid response to fault currents, minimizing potential damage to connected equipment. The 3VA5191-1MH31-0AA0 is designed without connection terminals, providing flexibility in choosing appropriate connection methods for the installation. This circuit breaker is ideal for applications where reliable short-circuit protection is paramount and overload protection is handled separately. Its compact design and robust construction make it suitable for a variety of industrial and commercial settings. Siemens' commitment to quality ensures long-term reliability and performance.
