Above 50 °C the curve steps down: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, 150 A at 70 °C. That thermal profile means you can size the breaker for a 160 A bus without oversizing the enclosure ventilation, as long as the internal ambient stays under 50 °C. Breaking capacity is specified per voltage level: 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. For a 480 V panel the relevant figure is the 440 V rating (32 kA) — the next step down in the standard voltage ladder. That gives you the SCCR headroom for most industrial distribution boards fed from a typical 1 MVA transformer. ## TM240 release and line protection design The overcurrent release is a TM240 thermal-magnetic type — fixed thermal pickup at 160 A (the breaker's frame rating) and magnetic instantaneous trip set at 240 A. The auxiliary switch configuration is two HP-style switches — these are the standard form-C contacts for status indication back to a PLC or a panel lamp. No communication function, no voltage-triggered accessory; the breaker is purely electromechanical. The 3-pole width (76.2 mm) matches the standard SENTRON 3VA1 frame footprint — it occupies three 25.4 mm pole spaces on a DIN rail or a mounting plate. The basic switch supplied is order code 3VA11163EF320AA0, which is the internal switching mechanism; the complete breaker includes the TM240 release and the two auxiliary switches pre-assembled.","metaTitle":"Siemens 3VA1116-3EF32-0AB0 SENTRON MCCB, 160A, 75.6kA at 240","metaDescription":"Siemens SENTRON 3VA1116-3EF32-0AB0 molded case circuit breaker, 3-pole, 160A rated at 40°C, 75.6kA breaking at 240V.
