The Siemens SENTRON 3VA2116-5KP32-0KL0 is a 3-pole molded case circuit breaker rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That means it holds its full 160 A rating in a warm panel, which is the spec that matters when you're stacking breakers in a confined enclosure. Breaking capacity hits 187 kA at 240 V, 121 kA at 415/440 V, and still clears 75.6 kA at 500 V — high enough for most industrial service-entrance or distribution applications where fault current is substantial.
Communication function is onboard, so it can report status to a higher-level control system.
The 160 A continuous rating is flat across the 40–70 °C range — unusual for an MCCB, which typically derates above 40 °C. That flat curve means you can install it in a hot enclosure or near other heat sources without losing headroom. Maximum interrupting capacity of 1 600 A frames the breaker's ability to handle short-circuit currents; the minimum 240 A rating is the lower bound of the adjustable thermal-magnetic trip range.
