SENTRON 3VA1116-5FD46-0AA0 — 4-pole MCCB, 80 A, TM210 release
The Siemens SENTRON 3VA1116-5FD46-0AA0 is a 4-pole molded case circuit breaker rated for 80 A continuous, designed for line protection in distribution panels. Its TM210 thermal-magnetic overcurrent release handles overload and short-circuit protection without undervoltage or ground-fault monitoring built in. Interrupting capacity peaks at 187 kA at 240 V, steps down to 121 kA at 415 V, 75.6 kA at 440 V, and holds 17 kA at both 500 V and 690 V — covering most industrial distribution voltages with headroom for high-fault service-entrance panels. Thermal derating is minimal: the breaker carries a full 160 A at 40 °C through 50 °C, then drops to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. That 150 A floor at 70 °C means the 80 A rating is well within the thermal headroom even in a crowded, warm enclosure.
Panel fit and integration
Dimensions are 130 mm high, 101.6 mm wide, and 70 mm deep — a 4-pole footprint that fits standard Siemens SENTRON mounting bases. The IP40 front protection means it's suited for enclosed distribution boards where splash or tool ingress is not expected on the face. Rated insulation voltage is 800 V, and maximum power loss at rated current is 38 W — a figure to factor into enclosure thermal calculations, especially when multiple breakers are ganged in a single cabinet.
