SENTRON 3VA1196-3EF32-0AC0 — MCCB for Line Protection
It carries a continuous current rating of 16 A across ambient temperatures from 40 °C to 55 °C, derating to 15 A at 60 °C through 70 °C. Breaking capacity reaches 75.6 kA at 240 VAC, 52.5 kA at 415 VAC, and 32 kA at 440 VAC — figures that govern its fault-interruption capability in a distribution panel.
The 75.6 kA at 240 VAC is the headline interrupting rating; at 415 VAC it drops to 52.5 kA, and at 440 VAC to 32 kA. At 500 VAC and 690 VAC the rating holds at 11.9 kA. These values determine where the breaker sits in a selective coordination study — upstream of lower-rated devices that must clear faults before this one trips.
Thermal-Magnetic Release and Temperature Derating
The breaker holds 16 A continuously from 40 °C to 55 °C ambient; above that it derates to 15 A through 70 °C. Maximum power loss is 10.6 W per pole, which factors into enclosure thermal calculations.
Physical Fit and Auxiliary Switching
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that mounts on a DIN rail or panel base. The breaker ships with two factory-fitted auxiliary switches (HQ type) for remote status indication.
