The shunt trip (STL) release allows remote trip via a control signal, so it integrates into emergency-stop or undervoltage protection schemes. Rated current holds flat at 1000 A from 40 °C up to 50 °C, then derates to 960 A at 55 °C and 900 A at 70 °C. In a warm enclosure or high-ambient panel, plan for that thermal curve — the breaker doesn't lose headroom until past 50 °C. The 120 mm depth keeps it within typical distribution panel clearances without requiring deep gland plates. ## Sourcing and lifecycle — active, no LTB watch needed That means a replacement shunt trip can be ordered separately if the release fails in service. ## Breaking capacity across voltages — where it fits Breaking capacity scales with system voltage: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, 52.5 kA at 690 V. At 415 V — the most common industrial distribution voltage — 121 kA covers virtually all transformer sizes up to 2500 kVA. At 690 V the 52.5 kA rating still suits heavy motor circuits with high short-circuit current. ## Integration — panel fit and wiring notes Three-pole design with line protection trip curve (TM240 thermal-magnetic release). No undervoltage release fitted, no ground-fault monitoring — those are add-on accessories if the application requires them. The 330 W maximum power loss means ventilation in the enclosure matters; in a sealed cabinet with other high-current devices, account for the heat load. The communication function is absent — this is a stand-alone breaker, not a metering or networked unit.","metaTitle":"Siemens 3VA1510-5EF32-0JA0 SENTRON MCCB, 1000A, 121kA @415V","metaDescription":"Siemens SENTRON 3VA1510-5EF32-0JA0 molded case circuit breaker, 3-pole, 1000A rated at 40°C, 121kA breaking capacity at 415V AC.
