The Siemens SENTRON 3VA2216-5MN32-0AE0 is a 3-pole molded case circuit breaker (MCCB) rated at 160 A continuous, designed specifically for motor protection. It carries phase failure detection as standard, which is essential for preventing single-phasing damage on three-phase motor loads. The interrupting capacity reaches 187 kA at 240 V and 121 kA at 415 V, so it can handle high-fault-current scenarios common in industrial distribution panels.
Ratings and what they mean for fit
The 160 A rating holds across the full operating temperature range from -25 °C to 70 °C — no derating needed up to 70 °C ambient. That simplifies panel thermal calculations: you don't have to upsize the frame for a warm enclosure. The interrupting capacity drops to 75.6 kA at 500 V and 4.5 kA at 690 V, so verify the available fault current at your system voltage before specifying. Maximum power loss is 19.7 W, which is moderate for a 160 A frame. That matters for enclosure heat rise — account for it in the thermal budget if the breaker is in a sealed, non-ventilated panel alongside other heat sources.
Integration and panel fit
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that fits most Siemens SENTRON mounting bases and panel cutouts. The breaker accepts up to 4 HQ auxiliary switches, configurable for status signaling or remote trip indication. No undervoltage release or shunt trip is fitted from the factory; those are ordered separately if needed. The basic switch variant is 3VA2216-5MN32-0AA0 — the -0AE0 suffix indicates the factory-fitted accessories and packaging variant. If you're replacing an existing unit, verify the accessory configuration matches your current installation.
