Interrupting capacity is 75.6 kA at 240 V, dropping to 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V and 690 V. That 75.6 kA at 240 V is the headline number for North American 240/120 V split-phase or 240 V delta services; at European 400 V class, you still have 52.5 kA, which clears most industrial fault levels below large transformer secondaries. Three-pole construction, 800 V rated insulation voltage, and maximum power loss of 14.6 W. Useful for remote trip indication without stealing an auxiliary contact. ## Mounting dimensions and panel fit Width 76.2 mm (3 in), height 130 mm (5.12 in), depth 70 mm (2.76 in). The storage limits are wider because the breaker is not carrying current or under mechanical stress — the -40 °C floor matters if the panel is shipped or stored in an unheated warehouse in a cold climate.","metaTitle":"Siemens 3VA1150-3EF36-0AH0 SENTRON MCCB, 50A, 75.6kA at 240V","metaDescription":"Siemens 3VA1150-3EF36-0AH0 SENTRON molded case circuit breaker, 3-pole, 50A rated (40-70°C), 75.6kA interrupting at 240V.
