What this MCCB is and what it does
The Siemens SENTRON 3VA1132-6EF36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a TM240 thermal-magnetic overcurrent release and a continuous current rating of 32 A at 40 °C. Its interrupting capacity reaches 220 kA at 240 V AC, 154 kA at 415 V, 121 kA at 440 V, and holds 17 kA at both 500 V and 690 V — so it can handle high-fault locations like transformer secondaries or large motor control centers without cascading upstream. The TM240 release means the thermal element is fixed at 240 A for the magnetic pickup; the breaker itself is rated 32 A continuous, so it's sized for a 32 A feeder or branch circuit, not for the magnetic trip threshold.
Thermal derating and panel fit
Current rating holds at 32 A from 40 °C up to 50 °C, then derates to 31 A at 55–60 °C and 30 A at 65–70 °C — useful when the breaker sits in a crowded enclosure with limited airflow. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits most Siemens SENTRON panelboards and distribution blocks without re-drilling. Front face carries IP40 protection, so it's suited for general indoor panel use where tools or fingers won't contact live parts; no washdown rating, so keep it behind a sealed enclosure door in wet environments.
