Siemens 3VA2025-7JP46-0AA0 — SENTRON MCCB, 25 A, 4-Pole, ETU550
The Siemens 3VA2025-7JP46-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for 25 A continuous current, 4-pole configuration, with an ETU550 electronic trip unit. It is designed for line protection in distribution panels and motor control centers, with a communication function for integration into higher-level monitoring systems. The interrupting capacity is 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V — per the datasheet. This SCCR headroom means it can handle high-fault-current scenarios typical of industrial mains without cascading upstream. The continuous current rating holds flat at 25 A across the entire operating temperature range from 40 °C to 70 °C — no derating needed within that band. The insulation voltage is rated at 800 V.
Integration and Mounting
Panel footprint: 140 mm wide, 181 mm high, 86 mm deep. The 4-pole body mounts on a DIN rail or direct panel-mount via the screw terminals. IP40 on the front face — suitable for enclosed distribution boards where the front is operator-accessible but the interior is protected. The ETU550 electronic trip unit supports communication functions for remote monitoring and trip-event logging. No undervoltage release or ground-fault monitoring version is fitted on this variant.
