The Siemens SENTRON 3VA2116-5KP32-0JA0 is a 3-pole molded case circuit breaker rated for 160 A continuous current at 40–70 °C without derating — the full thermal range is flat at 160 A, so no capacity fade in a hot panel. Breaking capacity hits 187 kA at 240 V, 121 kA at 415/440 V, and still holds 75.6 kA at 500 V; at 690 V it drops to 3.7 kA, which tells you this breaker is sized for 400–500 V distribution, not 690 V motor circuits. Line protection design with a built-in shunt trip (STL) and communication function — the shunt trip lets a remote signal or undervoltage relay trip the breaker independently of the overload curve, useful for emergency-off or interlock circuits. No ground-fault monitoring on this variant.
Integration & Mounting
Dimensions: 181 mm high, 105 mm wide, 86 mm deep — fits standard SENTRON 3VA panel cutouts and busbar systems. The 105 mm width is the 3-pole footprint; if your existing panel was cut for a 3VA2116-5JP32-0AE0 (same frame size), it drops in without busbar or mounting-plate changes.
