Product details

The Siemens SENTRON 3VA1112-4ED22-0AA0 is a 2-pole molded case circuit breaker (MCCB) rated 125 A continuous at 40 °C, with a TM210 thermal-magnetic trip unit. Breaking capacity reaches 121 kA at 240 V AC and 75.6 kA at 415 V AC — figures that govern fault-clearing capability in a distribution panel. The 70 mm depth and 50.8 mm width fit standard MCCB mounting footprints; IP40 on the front suits enclosed panel installation.

Thermal derating and trip unit

Rated 125 A at 40 °C, 45 °C, and 50 °C; derates to 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. The TM210 trip unit provides fixed thermal and magnetic settings for line protection — no adjustable long-time or short-time pickup. For DC applications, refer to the 3VA device manual for switching power limits.
