What this 3VM1116-4EE36-0AA2 brings to the panel
The TM220 thermal-magnetic release gives you adjustable overload protection from 112 A to 160 A, and fixed short-circuit pickup at 10× In, so it's a straight-ahead line-protection breaker, not a motor-protection piece with electronic adjustments.
The 121 kA at 240 V is the headline number, but out here in the grease the 76 kA at 415 V is what tells you whether this breaker holds on a 400 V distribution bus. At 440 V it still clears 53 kA, and at 500 V it drops to 11.9 kA. That's a solid safety margin for a 480 V plant.
Thermal performance across the temperature range
At 55 °C it's still at 158 A, at 60 °C it's 155 A, and at 65 °C it's 153 A. At the top end of 70 °C ambient you're at 150 A.
Connection and mounting details
The main circuit connects via box terminals arranged for front connection — standard for panel-mounted MCCBs where you're landing cable lugs or bus bars from the front. There are no auxiliary contacts included (0 CO contacts), and there's no provision for a motor drive or neutral conductor retrofit. The overcurrent release is the TM220 thermal-magnetic type with LI (long-time and instantaneous) protection, no ground-fault monitoring.
