What this MCCB does and where it fits
The Siemens SENTRON 3VA1110-6EF36-0BH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection — meaning it guards feeder and distribution circuits against overload and short-circuit, not motor or generator windings directly. Its TM240 thermal-magnetic release provides fixed thermal and magnetic trip thresholds; the thermal element tracks the 100 A continuous rating across the 40 °C to 50 °C band without derating, then drops to 96 A at 55 °C and 90 A at 70 °C, so a panel sitting near a boiler house or unvented enclosure needs that headroom accounted for in the load schedule.
Interrupting capacity — what the numbers mean for coordination
Rated short-circuit breaking capacity is 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 690 V. At 415 V, that 154 kA figure is well above typical utility fault levels in most industrial low-voltage networks, so this breaker can be placed at the main distribution point without worrying about cascading failure into downstream gear — provided the upstream transformer and bus bracing are rated for that prospective fault current. The 17 kA at 690 V is a reminder that the interrupting capability falls off steeply above 480 V; if the system is 690 V, verify the available fault current stays under that ceiling or step up to a higher-rated 3VA frame.
Auxiliary and undervoltage release configuration
This variant ships with an undervoltage release (UVR) — design of the auxiliary release is undervoltage release (UVR) — and the auxiliary contact block is 2 auxiliary switches plus 1 trip alarm switch HQ. The integrated auxiliary trip order code is 3VA9608-0BB11. The UVR means the breaker trips if control voltage drops below a set threshold, which is standard for safety circuits that must fail to a safe state on loss of control power. No communication function, no phase failure detection, no ground fault monitoring — this is a plain-vanilla thermal-magnetic MCCB with UVR, suited for conventional distribution where those extras aren't required.
