Rated current is flat at 50 A from 40 °C through 50 °C ambient, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. ## Breaking Capacity by Voltage — SCCR Planning The 3VA1150-5EF36-0DA0 delivers 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. The steep drop above 440 V is typical for this frame size — the arc extinction physics limit the interrupting rating at higher line voltages. For a 480 V panel, the relevant figure is the 440 V rating (75.6 kA), since the breaker's performance at 480 V is bounded by the next-lower tested voltage point. The breaker measures 130 mm high, 76.2 mm wide (3 in), and 70 mm deep. The depth of 70 mm (2.76 in) leaves clearance behind the panel for wiring and the UVR coil connections. Maximum power dissipation is 17.1 W at rated load.","metaTitle":"Siemens 3VA1150-5EF36-0DA0 SENTRON MCCB, 50 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1150-5EF36-0DA0 molded case circuit breaker, 50 A rated at 40 °C, 3-pole, 187 kA breaking capacity at 240 V.
