The shunt trip lets a remote signal (e.g., emergency-stop relay or fire-alarm panel) open the breaker without a manual trip. The auxiliary switches report the main-contact position back to a PLC or status lamp. For a panel that runs hot — say 55 °C ambient inside the enclosure — the breaker still carries 24 A continuous, which is 96 % of the nameplate. That is a shallow derating curve typical of SENTRON 3VA; you do not need to oversize for a warm cabinet unless the load is right at the limit. The 76.2 mm width (3 inches) is standard for a 3-pole MCCB in this frame size; it occupies one 3-module position on a DIN-rail assembly.","metaTitle":"Siemens 3VA1025-4ED32-0HC0 SENTRON MCCB, 25 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1025-4ED32-0HC0 molded case circuit breaker, 25 A, 3-pole, 121 kA breaking capacity at 240 V AC.
