The TM210 release is fixed at 320 A instantaneous (li min and li max both 320 A), so it's a non-adjustable magnetic trip; the thermal element carries the full 25 A through 50 °C ambient, then derates to 24 A at 55–60 °C and 23 A at 65–70 °C. Rated insulation voltage Ui is 500 VAC; maximum DC operating voltage is 125 V. Power dissipation at rated load is 2.83 W maximum, which matters for thermal budgeting inside a densely packed panel. The breaker occupies a 25.4 mm (1 in) width per pole — standard for a 1-pole SENTRON 3VA frame. Overall dimensions are 130 mm height by 70 mm depth.","metaTitle":"Siemens 3VA1125-5ED16-0AA0 SENTRON MCCB, 1-Pole 25 A, 121 kA","metaDescription":"Siemens 3VA1125-5ED16-0AA0 SENTRON molded case circuit breaker, 1-pole, 25 A, 121 kA at 240 VAC.
