The Siemens SENTRON 3VA2025-6HM36-0AA0 is a 3-pole molded case circuit breaker (MCCB) designed for line protection, carrying a rated continuous current of 25 A across its full operating temperature range from -25 °C to 70 °C with no derating needed. Its breaking capacity is substantial: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V — meaning it can safely interrupt high fault currents across common industrial voltage levels without upstream cascading. The unit measures 86 mm deep, 105 mm wide, and 181 mm high, fitting standard panel cutouts for 3-pole MCCBs in this class.
Rated insulation voltage of 800 V and a maximum power loss of 0.84 W mean it runs cool in a closed panel — thermal management is not a concern even in densely packed enclosures. The trip indicator is absent on this variant, and there is no undervoltage release or communication function — it is a straightforward thermal-magnetic MCCB for basic overcurrent and short-circuit protection. Storage temperature range of -40 °C to 80 °C covers unheated warehouses and shipping containers; operating range of -25 °C to 70 °C suits most indoor industrial environments.
