What the ratings mean for a kiln or panel
The 3VA1110-5EE32-0CH0 is a 3-pole SENTRON molded case circuit breaker rated for 100 A continuous current at 40 °C, with a TM220 thermal-magnetic release tuned for line protection. The interrupting capacity sits at 187 kA at 240 V and still delivers 121 kA at 415 V — enough headroom to clear a high-fault bus without cascading upstream. That SCCR matters when the breaker sits downstream of a large transformer or in a cement plant where the dust and heat already stress every joint. Operating range runs from -25 °C to 70 °C, and the rated current holds at 100 A all the way to 50 °C. Above that it derates smoothly — 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, 90 A at 70 °C. For a panel sitting near a kiln or in an unvented enclosure, that derating curve is the one that governs the real load you can hang on it. It carries an undervoltage release (UVR) as standard, plus 2 auxiliary switches and a separate trip alarm switch (HQ). The auxiliary contact version is built into the breaker — no external add-on needed for status feedback to a PLC or alarm annunciator.
Panel fit and integration
Dimensions: 130 mm high, 76.2 mm wide, 70 mm deep. The 76.2 mm width is a standard 3-pole MCCB footprint — it drops into the same panel cutout as other SENTRON 3VA frames. The IP40 front face keeps dust out of the mechanism in a clean panel environment; for washdown or outdoor duty you would need an enclosure around it.
