The TM210 designation on the overcurrent release means a thermal-magnetic trip with fixed settings — no interchangeable trip unit, no electronic adjustments. This is a straightforward, field-proven design for standard feeder and branch-circuit protection where you don't need the selectivity tuning of an electronic release. Breaking capacity is specified across five voltage points: 187 kA at 240 V AC, 121 kA at 415 V AC, 75.6 kA at 440 V AC, and 17 kA at both 500 V and 690 V AC. The 187 kA figure at 240 V is well above typical utility fault levels in North American 277/480 V panels when the breaker is applied on the 240 V line-to-line tap. At 690 V the 17 kA rating is the limiting case for European 400 V systems — coordination studies should use the 415 V or 440 V column depending on actual line voltage. The 3VA1150-5ED32-0AA0 is a 3-pole MCCB with a width of 76.2 mm (3 in), depth of 70 mm (2.76 in), and height of 130 mm (5.12 in). These dimensions match the standard 3VA1110 frame footprint — so if you're replacing a 3VA1110-5ED32-0AA0 in an existing panel, the mounting holes and bus-bar spacing are identical. No rewiring or bus rework needed. This is standard for panel-mounted MCCBs inside an IP54 or higher enclosure — no gasketing required on the front bezel. Maximum power dissipation is 14.6 W at rated load. In a dense panel with multiple breakers side by side, that heat adds to the enclosure's internal rise — factor it into your thermal calculation if the panel is near the 70 °C operating maximum. The storage minimum of -40 °C covers cold warehouse conditions without special handling. It is a plain thermal-magnetic breaker — add external accessories if those functions are required.","metaTitle":"Siemens 3VA1150-5ED32-0AA0 SENTRON MCCB, 50 A, 3-Pole, TM210","metaDescription":"Siemens SENTRON 3VA1150-5ED32-0AA0 molded case circuit breaker, 50 A rated at 40 °C, 3-pole, TM210 thermal-magnetic release.
