The Siemens SENTRON 3VA2110-6HL32-0AH0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at up to 70 °C ambient — no derating needed across the full temperature range. It is designed for line protection in distribution panels, with a breaking capacity of 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. The 800 V rated insulation voltage suits it for 400 V and 690 V systems. The 86 mm depth, 105 mm width, and 181 mm height fit standard Siemens switchboard mounting.
At 415 V and 440 V the 187 kA rating still covers most industrial service-entrance and feeder applications. The drop to 3.7 kA at 690 V means this breaker is not intended for 690 V main feeders; it is a 240–500 V device. The 100 A continuous rating holds flat from 40 °C through 70 °C, so no thermal derating is needed even in a warm enclosure.
