What it is and what the ratings mean
The Siemens 3VA1132-6EF36-0HH0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection in distribution panels. It's a 3-pole unit rated 32 A at 40 °C, with a rated insulation voltage of 800 V. The headline number here is the interrupting capacity: 220 kA at 240 V AC, dropping to 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V and 690 V. That 220 kA figure means it can safely clear a fault of that magnitude on a 240 V supply without rupturing — critical for high-fault locations like a main service entrance or a large motor control center where the available fault current is substantial. The 32 A continuous rating holds flat from 40 °C up to 50 °C, then derates slightly to 30 A at 70 °C, which is a solid thermal curve for a panel that might run warm.
Auxiliaries and integration
This MCCB comes factory-fitted with 2 auxiliary switches plus 1 trip alarm switch (HQ designation) and a shunt trip release (STL). That means you get remote status indication and the ability to trip the breaker from a remote pushbutton or a safety relay — useful for emergency-stop circuits or remote shutdown sequences. The shunt trip is a separate voltage-triggered release, so you don't need an undervoltage release module for that function. The breaker itself is 70 mm deep, 76.2 mm wide, and 130 mm tall, which is a standard SENTRON 3VA footprint for a 3-pole frame at this rating. It will fit existing 3VA panel cutouts and busbar arrangements without modification.
