The Siemens SENTRON 3VA1125-4ED26-0AA0 is a 2-pole molded case circuit breaker (MCCB) rated 25 A at 40 °C, designed for line protection in distribution panels. Its TM210 thermal-magnetic release provides fixed overload and short-circuit protection without adjustable trip settings — a straightforward fit for standard feeder circuits where coordination is set by the breaker rating, not field tuning. Breaking capacity hits 121 kA at 240 V AC and 75.6 kA at 415 V AC, giving substantial SCCR headroom for high-fault installations. The 70 mm depth and 50.8 mm width keep the footprint compact for a 25 A MCCB — mounts cleanly on a DIN rail or panel-mount base inside a standard enclosure.
Lifecycle & Sourcing
This part carries a current-production lifecycle status. Sourced to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
Integration Notes
Front face carries IP40 protection — suitable for dry indoor panels where dust ingress is minimal. Rated operating temperature range from -25 °C to 70 °C; storage range from -40 °C to 80 °C. The TM210 release is non-interchangeable, so verify the 25 A rating matches your load before mounting. No undervoltage release, no ground-fault monitoring, no communication function — this is a basic thermal-magnetic MCCB for simple overcurrent protection. Insulation voltage rated 500 V; AC operating voltage 415 V, DC operating voltage 250 V.
