The N-conductor protection is adjustable from OFF to 20%–100% of the phase rating, giving flexibility for systems where the neutral is undersized or needs to be switched off. No undervoltage release or voltage trip is fitted as standard — those would be add-on accessories. ## Thermal Performance and Environmental Range That is unusual for a molded case breaker; most start derating above 40 °C. The maximum power loss is 19.7 W, which is moderate for a 160 A frame and manageable in a ventilated enclosure. The IP40 front protection means it is suited for indoor panel mounting, not washdown environments. As a Siemens SENTRON product, the 3VA2116-0KQ42-0AA0 carries the usual compliance documentation for industrial MCCBs: CE marking for the European market, UL/CSA listing for North America, and RoHS/REACH declarations. Specific certificate numbers should be verified against the project's local code requirements.","metaTitle":"Siemens 3VA2116-0KQ42-0AA0 SENTRON MCCB, 160 A, ETU860, 4-Po","metaDescription":"Siemens SENTRON 3VA2116-0KQ42-0AA0 molded case circuit breaker, 160 A continuous, ETU860 electronic trip, 4-pole, 440 kA at 415 V.
