The Siemens SENTRON 3VA2116-5HL36-0DC0 is a 3-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. Breaking capacity hits 187 kA at 240 V AC, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V, so it handles high-fault utility feeds or transformer secondaries without cascading upstream. The part carries an undervoltage release (UVR) and two auxiliary switches HQ, factory-integrated into the supplied basic switch 3VA21165HL360AA0.
Panel footprint: 105 mm wide, 181 mm tall, 86 mm deep — fits standard MCCB mounting cutouts in SENTRON distribution boards or standalone enclosures. The undervoltage release trips on loss of control voltage; verify the release coil is powered from a stable 24 VDC supply if used as a remote shunt. Two auxiliary switches HQ provide status feedback for PLC or indication circuits.
