IEC Frame 160 Starter protection TM120M AM protection High short-circuit setting (Ii) Terminal connection

Product description

The Siemens 3VA1112-5MH36-0AA0 is a 3-pole circuit breaker from the 3VA1 IEC Frame 160 series, specifically designed for starter protection applications. It features a breaking capacity class M with an Icu of 55 kA at 415V. This model utilizes TM120M AM protection with a rated current (In) of 125A and is designed without overload protection, focusing on short-circuit protection (Ii=7...16 x In) via terminal connection.

This breaker is suitable for protecting electric motors and other starting equipment where precise short-circuit interruption is critical and overload is managed by other means. Its higher short-circuit trip setting (Ii) is optimized for motor starting characteristics.
