3VA5225-1MH31-0AA0 SIEMENS

The 3VA5225-1MH31-0AA0 is a robust 3-pole circuit breaker from Siemens, designed for starter protection within UL Frame 250 applications. This circuit breaker features a TM120M trip unit, configured for AM (Starter Protection) type protection. It has a rated current (In) of 250A, making it suitable for demanding motor starting applications. The device is equipped with short-circuit protection (Ii) adjustable from 5 to 10 times the rated current (In), providing effective protection against short-circuit events. Notably, this model does not include overload protection, focusing solely on short-circuit and starter-specific fault conditions. This makes it ideal for use in conjunction with other protective devices that handle overload scenarios. The absence of a connection further allows for flexible integration into various electrical systems, depending on specific installation requirements. As part of the 3VA5 series, it offers reliable performance and meets stringent quality standards. This circuit breaker is designed to enhance the safety and reliability of motor starter circuits. It ensures rapid interruption of fault currents to prevent damage to connected equipment.
