The Siemens SENTRON 3VA1110-3GF42-0AA0 is a 4-pole molded case circuit breaker rated 100 A continuous, designed for line protection in distribution panels. It carries a TM240 thermal-magnetic overcurrent release — the 240 refers to the frame size, and the breaker is fully rated at 100 A without derating up to 50 °C ambient; above that it drops to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. Interrupting capacity varies by line voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V and 690 V. The 70 mm depth and 101.6 mm width make it a standard-fit for most 4-pole MCCB slots in Siemens SENTRON switchboards.
Integration Notes
The 4-pole format covers three-phase plus neutral switching. The TM240 release is fixed — no interchangeable trip units. Front protection is IP40, so the breaker is suited for enclosed panel mounting; no washdown rating. No undervoltage release, no shunt trip, and no communication function are fitted on this variant. Maximum power dissipation is 25 W, which should be factored into enclosure thermal calculations. The insulation voltage rating is 800 V, adequate for 690 V line-to-line systems.
