It carries an undervoltage release and two HQ auxiliary switches built in — no add-on module needed for basic trip signaling or shunt control. At 415 V the interrupting rating is 75.6 kA, dropping to 52.5 kA at 440 V and 11.9 kA at both 500 V and 690 V. That gives the panel designer clear selectivity boundaries: at 400 V class the breaker can clear a bolted fault downstream of a larger upstream device without nuisance trip of the main. ## Thermal derating and power dissipation Derating starts at 55 °C (158 A) and drops to 150 A at 70 °C. For a panel with internal temperature rise of 15–20 K above room ambient, that means the breaker can be loaded to nameplate in a 50 °C enclosure without forced ventilation. Maximum power loss is 40.5 W — relevant for thermal simulation of densely packed distribution boards. ## Integrated auxiliary and release options Factory-fitted with two HQ auxiliary switches and an undervoltage release (UVR). No trip indicator or voltage trigger is installed; no communication module or ground-fault monitoring is present on this variant. ## Environmental limits The storage minimum matters for unheated warehouses in cold climates — the breaker can sit at -40 °C without damage, though it must be warmed above -25 °C before energizing.","metaTitle":"Siemens 3VA1116-4EF32-0BC0 SENTRON MCCB, 160 A, 3-Pole, 121","metaDescription":"Siemens SENTRON 3VA1116-4EF32-0BC0 molded case circuit breaker, 160 A, 3-pole, 121 kA breaking capacity at 240 V.
