Its interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V — figures that govern its placement in a selective coordination study. At 55 °C it derates to 62 A, at 60 °C to 61 A, at 65 °C to 60 A, and at 70 °C to 58 A. If the breaker lives in a non-air-conditioned enclosure near a heat source, use the 58 A figure at 70 °C for the continuous load calculation — not the catalog 63 A. The 3-pole width of 76.2 mm (3 inches) matches the standard MCCB footprint for a 63 A frame — it occupies one 3-inch slot in a panelboard or switchboard. No special adapter plate needed for a standard SENTRON mounting base. ## Power loss budget Maximum power dissipation is 17.3 W at rated current. For a 3-pole breaker in a sealed enclosure, that 17.3 W contributes to the internal temperature rise — factor it into the thermal derating calculation above.","metaTitle":"Siemens SENTRON 3VA1163-5EF36-0AA0 MCCB, 63 A, 3-Pole, TM240","metaDescription":"Siemens SENTRON 3VA1163-5EF36-0AA0 molded case circuit breaker, 63 A continuous, 3-pole, TM240 release. 187 kA at 240 V.
