The single-pole construction switches the positive leg only; neutral is not switched, so the breaker must be installed in the ungrounded conductor per the polarity marking on the device. Temperature derating is significant: at 40 °C the rating drops to 15.1 A, at 50 °C to 14.16 A, and at 60 °C to 13.14 A. If the panel ambient runs 50 °C, size for 14 A continuous load, not 16 A. The humidity envelope caps at 95% RH up to 55 °C, then derates to 35% RH at 75 °C — relevant for unventilated enclosures in humid tunnels or washdown areas.","metaTitle":"Siemens SENTRON 5SY5116-6CC12 MCB, B-16 A, 1P DC, 10 kA","metaDescription":"Siemens SENTRON 5SY5116-6CC12 miniature circuit breaker, 1-pole DC, B characteristic, 16 A at 35 °C, 10 kA breaking capacity, 250 V DC max, railway-rated, current production.

The 5SY5116-6CC12 is the railway-specific variant with the 50 m/s² vibration rating and wider temperature range (-40 to 75 °C). Do not assume drop-in interchangeability without verifying the DC voltage rating and breaking capacity of the alternative against your application."},{"question":"Where can I buy 5SY5116-6CC12?","answer":"This part is sourced and quoted to order against an RFQ through independent industrial-automation distribution.
