The Siemens SENTRON 3VA2110-5JP32-0KC0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying 100 A continuously at 40 °C and interrupting up to 187 kA at 240 V.
At 55 °C it drops to 96.25 A, at 60 °C to 92.5 A, and at 70 °C to 85 A. The interrupting curve falls off with voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V. The shunt trip (STL) is built in — part number 3VA9688-0BL33 for the integrated auxiliary trip. Two auxiliary switches (HQ type) are included, giving you status feedback for the PLC or a remote annunciator. Communication function is present — the ETU550 supports it via a plug-in module.
Panel fit
That 105 mm width is a standard 4-module (4 x 27 mm) footprint for SENTRON 3VA2 breakers — it clips onto the mounting plate or DIN rail adapter. The 86 mm depth includes the handle and terminals; leave clearance for cable bending radius below the line and load lugs.
