The Siemens SENTRON 3VA2116-7HM42-0AF0 is a 4-pole molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. It carries a line protection role, meaning it's the main feeder breaker in a distribution panel, not a motor-protective device. The interrupting capacity tells the story: 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The ETU330 electronic trip unit inside gives you adjustable long-time, short-time, and instantaneous protection curves plus ground-fault monitoring via summation current sensing on L+N conductors. That's the kind of selectivity you need when coordinating downstream branch breakers.
Panel Fit & Integration
That's a 4-pole MCCB that fits the standard SENTRON mounting pattern. Maximum power dissipation is 25.5 W at rated load.
What It Replaces or Crosses To
The 3VA2116 is a 160 A frame versus the 100 A frame on the 3VA2110-7HK42-0AA0. Same 4-pole, same ETU330 trip.
