SENTRON 3VA2 MCCB — 160 A, 3-Pole, Line Protection
Breaking capacity is rated 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — so at typical 400 V distribution voltages it clears fault currents well above most panel SCCR requirements without cascading upstream. The breaker ships with two HQ auxiliary switches and the undervoltage release pre-installed; the basic switch model is 3VA21165KP320AA0. No ground-fault monitoring module is included on this variant.
Panel Fit and Thermal Performance
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — the width is standard for a 3-pole SENTRON 3VA2 frame, so it drops into existing 3VA2 panel cutouts without modification. Maximum power loss is 28 W, manageable with natural convection in most enclosures. The unit is designed for fixed installation in distribution boards — no DIN-rail mounting on this frame size.
