Interrupting capacity hits 187 kA at 240 V, 121 kA at 415/440 V, and still holds 75.6 kA at 500 V — high enough for most main feeder or large motor branch applications where fault current is substantial. The interrupting ratings tell you the maximum fault current the breaker can safely clear at each voltage: 187 kA at 240 V is typical for a main on a large low-voltage transformer; 121 kA at 415 V covers most industrial distribution; the drop to 3.7 kA at 690 V means this frame is not intended for 690 V main service — it's a 480 V class device. The ETU850 trip unit gives you curve shaping (LSIG) and communication, so it's suited for selective coordination studies and remote trip diagnostics. ## Panel integration Front IP40 protection means it's splash-protected on the face. The ETU850 supports communication, so plan for a communication cable route to the panel controller. The trip indicator is visible on the front.","metaTitle":"Siemens 3VA2116-5KP32-0AJ0 SENTRON MCCB, 160 A, 187 kA","metaDescription":"Siemens 3VA2116-5KP32-0AJ0 SENTRON molded case circuit breaker, 3-pole, 160 A continuous, ETU850 trip unit, 187 kA at 240 V.
