The interrupting capacity tells the real story: 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. For a 100 A frame, those numbers mean it can sit upstream of a transformer or a feeder panel and still clear a bolted fault without the arc flash climbing upstream. The initial setting starts at 20 A and the full-scale value is 100 A, so it's adjustable within that band — useful when you're protecting a variable load and want to dial in coordination without swapping the breaker. This breaker carries a communication function, which means it can report status or trip events back to a controller — useful for a maintenance team that wants to know why a line dropped without walking the panel. The auxiliary switch configuration is 4 HQ switches, which gives you four independent signal contacts for remote indication or interlocking. Those dimensions are for the breaker body itself; you'll need to account for the handle throw and any auxiliary wiring space. ## What the interrupting ratings mean for coordination At 240 V, the 187 kA interrupting rating is high enough to be used as a main breaker in most low-voltage switchboards without worrying about series ratings. The drop to 75.6 kA at 500 V and 3 kA at 690 V is typical for a 100 A frame — at 690 V you're limited to relatively low-fault systems.","metaTitle":"Siemens 3VA2010-5JQ32-0AE0 SENTRON MCCB, 100 A, 187 kA at 24","metaDescription":"Siemens 3VA2010-5JQ32-0AE0 SENTRON molded case circuit breaker, 3-pole, 100 A rated at 40-70 °C, 187 kA interrupting at 240 V.
