What this MCCB carries and where it fits
The Siemens 3VA2110-5HL36-0DH0 is a SENTRON 3VA2 molded case circuit breaker rated for 100 A continuous current across the full 40 °C to 70 °C ambient range, meaning no derating is needed in a warm panel — the breaker holds its full 100 A all the way up to 70 °C. Three-pole construction, line-protection design, with an undervoltage release (UVR) integrated and a 2-auxiliary-switch plus 1-trip-alarm-switch HQ complement for status feedback to a PLC or annunciator. Breaking capacity is 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the 187 kA figure at 240 V covers high-fault utility feeds common in North American distribution, while the 121 kA at 415 V handles European industrial networks. Dimensions are 86 mm deep, 105 mm wide, 181 mm tall — the 105 mm width is the standard 3-pole MCCB footprint for a 100 A frame, so it drops into existing SENTRON panel-mounting plates or DIN-rail adapters without re-drilling.
Sourcing and lifecycle posture
Maximum power loss is 12.5 W — a modest thermal load for a 100 A frame, but worth accounting for in a densely packed panel with multiple breakers side by side.
Integration and auxiliaries
The basic switch assembly carries order code 3VA21105HL360AA0 — this is the internal switching mechanism; the complete breaker ships with it installed. Undervoltage release (UVR) is built in — trips the breaker if control voltage drops below the dropout threshold, standard for emergency-stop circuits or undervoltage protection of motor feeds. Auxiliary switch complement is 2 form-C (changeover) switches plus 1 trip-alarm switch HQ — the HQ contact closes only on a fault trip, giving a distinct signal from a manual open. No communication function or ground-fault monitoring on this variant — it is a pure line-protection MCCB with local indication only.
