Motor-protection MCCB with full-current flat rating and 330 kA interrupt at 240 V
The Siemens SENTRON 3VA2216-7MN32-0AE0 is a 3-pole molded case circuit breaker (MCCB) rated 160 A continuously from 40 °C through 70 °C — no derating needed across that band, which simplifies panel build and saves a line-item check on the BOM. Its interrupting capacity hits 330 kA at 240 V and stays at 242 kA through 440 V, then drops to 187 kA at 500 V and 4.5 kA at 690 V. That 330 kA figure at 240 V is the headline number for high-fault service-entrance or large-motor branch circuits where available fault current is high. This is a motor-protection design, meaning the trip curve and thermal memory are tuned for motor starting inrush — it will hold through a 6× to 8× FLA start and still clear a locked-rotor fault fast. Phase failure detection is built in, so a lost phase on the line side trips the breaker and prevents single-phasing damage to the motor. The breaker ships with the basic switch variant 3VA2216-7MN32-0AA0 and is configured with four HQ auxiliary switches. No undervoltage release, no ground-fault monitoring, and no communication function are fitted on this order code — it is a straight motor-protection MCCB for standalone or light-curtain integration.
Dimensions and panel fit
The breaker measures 105 mm wide × 181 mm high × 86 mm deep — a standard SENTRON 3VA2 frame footprint. It mounts via screw-clamp lugs; no DIN-rail adapter is used at this frame size. The 86 mm depth leaves clearance behind a standard 200 mm deep enclosure backplate for wiring and lug access.
Operating conditions and power loss
Ambient operating range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Maximum power loss at rated current is 19.7 W — a factor for enclosure thermal calculations if the panel is densely packed. Short-time delay is adjustable between 4 s and 17 s for selective coordination downstream.
