Description
About the 3VA1225-6EF42-0AA0
About the 3VA1225-6EF42-0AA0
The Siemens 3VA1225-6EF42-0AA0 is a four-pole molded case circuit breaker (MCCB) from the SENTRON 3VA1 series, rated 250 A with a breaking capacity of 70 kA (Icu) at 415 V AC (utilisation class H). It is equipped with the TM240 LI thermal-magnetic trip unit providing overload (L) and instantaneous short-circuit (I) protection. Rated for distribution and motor-feeder protection in low-voltage switchgear up to 690 V AC.
Certifications & Standards
- IEC 60947-2
Applications & Use Cases
At 250 A rated current and 70 kA breaking capacity, the 3VA1225-6EF42-0AA0 is dimensioned for feeder, sub-distribution and motor-circuit protection in low-voltage main and sub-distribution boards. The TM240 LI trip unit offers adjustable overload and short-circuit settings for selectivity coordination with upstream and downstream devices.
The IEC Frame 250 enclosure supports fixed mounting in form-separated switchgear (form 2–4) and accepts a range of Siemens 3VA accessories — auxiliary and alarm switches, shunt and undervoltage releases, rotary and motor operators — for adaptation to the specific installation and control scheme.
