The 70 mm depth, 76.2 mm width, and 130 mm height fit standard Siemens SENTRON panel footprints; the 3-pole block occupies three 25.4 mm module positions on the DIN rail. ## Thermal performance and power loss The breaker dissipates a maximum of 40.5 W at rated load — a figure to factor into enclosure thermal calculations, especially when multiple breakers are ganged. The continuous current rating holds flat at 160 A from 40 °C through 50 °C, then begins a gradual derating: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. This thermal curve is typical for thermal-magnetic MCCBs and governs the real-world ampacity in warm panels. ## Breaking capacity by voltage The interrupting rating varies with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The 75.6 kA at 240 V covers most North American 240/120 V distribution; the 52.5 kA at 415 V suits European 400 V networks. The 3VA1116-3EF32-0CH0 measures 70 mm deep, 76.2 mm wide, and 130 mm tall. The trip indicator is present, giving a visual flag when the breaker has tripped on fault.","metaTitle":"Siemens 3VA1116-3EF32-0CH0 SENTRON MCCB, 160 A, 75.6 kA","metaDescription":"Siemens SENTRON 3VA1116-3EF32-0CH0 molded case circuit breaker, 160 A at 40 °C, 75.6 kA breaking at 240 V. 3-pole with undervoltage release.
