Siemens
3VA2
Siemens 3VA2 MCCBs provide electronic overcurrent protection in a 160 A frame, with 63 A variants spanning six ETU trip unit models from basic LI to full LSIG selectivity. 3-pole and 4-pole configurations offer 55 kA or 85 kA breaking capacity at 415 V, with terminal, clamp, and nut-keeper connections. Integrated N-protection and ground-fault detection on select models extend coverage to main and feeder applications. The ETU electronic platform delivers temperature-compensated tripping independent of ambient conditions for simplified network coordination.
