The Siemens SENTRON 3VA2110-0KP46-0AA0 is a 4-pole molded case circuit breaker rated 100 A continuous at 40 °C, with an ETU850 electronic trip unit that supports adjustable N-conductor protection (OFF, 20 % to 160 %).
At 86 mm deep, 140 mm wide, and 181 mm tall, the 3VA2110-0KP46-0AA0 fits the standard SENTRON 3VA frame footprint.
Trip unit and protection capabilities
The N-conductor protection can be set from OFF to 20 %–160 % of the rated current, which is useful for systems with harmonic loads or unbalanced neutral currents. Rated insulation voltage is 800 V, and the breaker handles ambient temperatures from -25 °C to 70 °C, with no derating needed up to 70 °C (100 A continuous across the full range).
