The undervoltage release is integrated — it will trip on loss of control voltage, a common requirement for emergency-stop circuits and safety disconnects in conveyor or pump panels. Above that it derates linearly: 24.06 A at 55 °C, 23.13 A at 60 °C, 22.19 A at 65 °C, and 21.25 A at 70 °C (–). In a sealed enclosure or next to heat-generating drives, that 70 °C ceiling is the real limit — not the 25 A label. The 140 mm width and 107 mm depth fit a standard 4-pole MCCB footprint; the IP40 front means the face is protected against tools and wires >1 mm but not against moisture, so mount it in a dry, lockable section of the panel.","metaTitle":"Siemens 3VA2125-5JQ46-0CJ0 SENTRON MCCB, 25 A, 187 kA at 240","metaDescription":"Siemens 3VA2125-5JQ46-0CJ0 SENTRON molded case circuit breaker, 25 A rated current, 187 kA interrupting at 240 V.
