Part identity and key ratings
The Siemens SENTRON 3VA2010-5JP36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C, with no derating required up to the maximum operating temperature. Its interrupting capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — figures that define the available fault current it can safely clear at each voltage level without upstream coordination failure. This is the line protection version, fitted with an ETU550 electronic overcurrent release, and it includes a communication function for integration into higher-level monitoring or control systems.
Physical fit and panel integration
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a footprint that matches the standard SENTRON 3VA2 frame and will drop into existing panel cutouts or DIN-rail mounting arrangements for the series. Front face protection is IP40, suitable for enclosed panel installations where tools are required to access the breaker; the optional motor drive extension (listed as available) allows remote tripping or reset without opening the door.
Electrical ratings and application context
Rated insulation voltage is 800 V. Maximum power loss at rated current is 13.5 W — a figure that matters for thermal management inside a sealed enclosure, especially when multiple breakers are ganged. Storage temperature range is -40 °C to 80 °C; operating range is -25 °C to 70 °C, so the breaker can be warehoused in unheated spaces but must be within the narrower band when carrying load.
