In a hot panel — say, next to a transformer or in a non-ventilated enclosure — the 23 A limit at 70 °C is the number to use for your load calculation, not the 25 A nameplate. Operating voltage is 415 V AC or 250 V DC; insulation voltage is rated 500 V. Dimensions are 70 mm deep, 50.8 mm wide, 130 mm tall — a standard 2-pole MCCB footprint that fits most DIN-rail or panel-mount bases in the SENTRON range.","metaTitle":"Siemens 3VA1125-5ED22-0AA0 SENTRON MCCB, 25A, 2-Pole, 187kA","metaDescription":"Siemens 3VA1125-5ED22-0AA0 SENTRON molded case circuit breaker, 25A rated, 2-pole, TM210 release, 187kA at 240V AC interrupting capacity.
