The LI protective function (long-time and instantaneous) covers cable and busbar protection in line distribution panels. Breaking capacity steps down with voltage: 121 kA at 240 V, 76 kA at 415 V, 53 kA at 440 V, and 11.9 kA at 500 V. For a site electrical engineer working on selectivity, the S-class switching capacity (36 kA Icu at 415 V per the description) gives headroom for downstream coordination with smaller MCCBs or MCBs. The 50 A continuous rating holds flat through 50 °C, then derates to 49 A at 55 °C and 45 A at 70 °C — useful when the breaker sits in a warm enclosure near other heat sources. ## Mounting and connection details Front-connected box terminals accept the main circuit wiring. The IP40 front protection suits enclosed panel mounting — not washdown, but fine for dry indoor switchgear. The 160 A frame size gives physical room for larger cable lugs. No auxiliary contacts are fitted as standard (0 CO contacts), and no motor drive or neutral conductor upgrade is offered on this variant.","metaTitle":"SENTRON 3VM1150-4EE36-0AA2 MCCB, 50 A, 121 kA at 240 V","metaDescription":"SENTRON 3VM1150-4EE36-0AA2 molded case circuit breaker, 3-pole, 50 A rated, TM220 release, 121 kA at 240 V.
