It belongs to the SENTRON 3VA series, which covers the compact-to-high-performance range of Siemens MCCBs for commercial and industrial power distribution. Breaking capacity varies with system voltage: 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Thermal derating is minimal up to 50 °C (full 80 A), then drops to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. The auxiliary release design is specified as shunt trip (STL), and the auxiliary switch design carries 2 auxiliary switches HQ. No undervoltage release, ground-fault monitoring, or communication function is included on this order code.
Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth — a standard 3-pole MCCB footprint that fits Siemens SENTRON distribution panels and most DIN-rail or base-mount enclosures. The 3-pole design covers three-phase circuits; line protection design means it is set up for feeder or branch-circuit protection, not motor-protective coordination out of the box. The cold end covers freezer and cold-storage environments common in refrigeration and cold-chain applications — the breaker runs cold and stays cold down to -25 °C ambient.
