Product details

Siemens SENTRON 3VA2110-8HN42-0AA0 – 100 A, 4-Pole MCCB with ETU350 Trip Unit

The Siemens SENTRON 3VA2110-8HN42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for a continuous current of 100 A across the full operating temperature range from 40 °C to 70 °C — no derating needed up to that ceiling. It carries a breaking capacity of 440 kA at 240 V AC, 330 kA at 415 V, and 220 kA at 500 V, making it suitable for high-fault-current industrial distribution panels.

Breaking Capacity and Trip Unit – What It Means for Your Panel

At 415 V the rating is still 330 kA, and at 690 V it drops to 52.5 kA — the physical arc-quenching limit at higher voltage. The ETU350 release is an electronic trip unit with adjustable pickup and time-delay settings, giving you selective coordination flexibility downstream.

Mounting and Integration – DIN-Rail or Panel-Mount

The 3VA2110-8HN42-0AA0 has a footprint of 140 mm wide by 181 mm high by 86 mm deep — a standard 4-pole MCCB form factor that fits most low-voltage switchboard cubicles.
