The Siemens SENTRON 3VA2110-5HN32-0JL0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 100 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Interrupting capacity sits at 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, which covers most industrial fault-current scenarios without cascading upstream.
What the ratings mean for fit
The 100 A continuous rating holds flat from 40 °C to 70 °C ambient — that is a full thermal band with no derate curve to calculate, which simplifies panel sizing in warm enclosures or near other heat sources. The 187 kA at 240 V is the high-end interrupting figure; at 415 V it still delivers 121 kA, enough for most low-voltage distribution boards. The 3.7 kA at 690 V is the tail — if your system runs at 690 V, verify the available fault current stays under that limit. The breaker ships with a shunt trip release (STL) and a complement of two auxiliary switches plus one trip alarm and one electrical alarm switch (HQ configuration). That means remote tripping and status feedback are built in without needing an add-on module.
Physical integration
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a standard MCCB footprint that fits most panel-mounted or DIN-rail adapters. The 3-pole design with line-protection trip curve suits feeder or branch-circuit duty in switchboards and motor control centers.
