The Siemens 3VA1116-5EE36-0KA0 is a SENTRON molded case circuit breaker (MCCB) rated for 160 A continuous at 40 °C ambient, with a 3-pole configuration and a TM220 thermal-magnetic overcurrent release. Its breaking capacity reaches 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V — covering standard industrial distribution voltages across the board.
Thermal derating and real-world fit
The 160 A rating holds steady through 50 °C ambient; above that it derates to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. In a warm panel — say a food-plant enclosure near ovens — that 150 A floor at 70 °C still leaves headroom for a 125 A continuous load.
Panel footprint and wiring
Depth is 70 mm, width 76.2 mm, height 130 mm.
What the TM220 release means in practice
The TM220 designation indicates a fixed thermal-magnetic trip: the thermal element protects against sustained overloads, the magnetic element against short-circuit currents. It's a straightforward, no-frills MCCB for a fixed-load application where you don't need remote monitoring or adjustable trip curves.
