The 210 mm width and 120 mm depth fit standard Siemens 3VA switchboard or distribution panel cutouts. ## Selectivity and coordination notes The interrupting ratings across voltages — 187 kA at 240 V, 121 kA at 415 V, 121 kA at 440 V, 75.6 kA at 500 V, 52.5 kA at 690 V — give the engineer the SCCR headroom for selective coordination with downstream breakers. No communication function — this is a stand-alone thermal-magnetic or electronic-trip MCCB without integrated fieldbus.","metaTitle":"Siemens 3VA1580-5EF32-0JL0 SENTRON MCCB, 800 A, 3-Pole, 121","metaDescription":"Siemens 3VA1580-5EF32-0JL0 SENTRON molded case circuit breaker, 800 A rated at 40 °C, 3-pole, interrupting 121 kA at 415 V.
