MCCB with ETU850 — 100 A, 4-Pole, Line Protection
The Siemens SENTRON 3VA2010-6KP42-0AA0 is a 4-pole molded case circuit breaker rated for 100 A continuous current, designed for line-protection duty in distribution panels and industrial switchboards. Breaking capacity reaches 242 kA at 240 V AC, 187 kA at 415/440 V, and 121 kA at 500 V — figures that place this MCCB comfortably in high-fault-current applications such as transformer secondaries or large motor control centers. The 100 A rating holds across the full ambient temperature range from 40 °C to 70 °C with no derating required, simplifying panel thermal calculations.
Panel Integration & Compliance
Dimensions are 181 mm height, 140 mm width, and 86 mm depth — a footprint that fits standard SENTRON 3VA panel cutouts and busbar systems. The ETU850 trip unit supports communication, enabling remote monitoring of load current and trip events via the SENTRON communication bus.
