MCCB with shunt trip for line protection
The Siemens SENTRON 3VA2010-5HL36-0JA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C through 70 °C with no derating across that range, per the datasheet.
Breaking capacity is specified at five voltage points: 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. The steep drop above 500 V means this breaker is sized for 480 V or 600 V class systems where the available fault current stays under 75 kA; at 690 V the 3 kA limit restricts it to low-fault installations.
