SENTRON 3VA1010-3ED36-0KA0 — 100 A MCCB with Shunt Trip for Line Protection
The Siemens 3VA1010-3ED36-0KA0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated 100 A at 40 °C, designed for line-protection duty. Its TM210 thermal-magnetic release handles overload and short-circuit protection, and the integrated shunt trip (STL) allows remote tripping via a control signal — useful for emergency-stop or supervisory shutdown circuits. The 75.6 kA interrupting rating at 240 V AC gives substantial fault-current headroom for most commercial and light industrial panelboards.
Breaking Capacity and Voltage Ratings
Interrupting capacity drops with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. For a 480 V panel, the 32 kA at 440 V is the closest published figure — expect a similar value at 480 V. The 800 V rated insulation voltage (Ui) confirms the breaker's internal clearance is designed for 690 V systems.
Thermal Derating and Ambient Temperature
Rated 100 A from 40 °C through 50 °C, then derates linearly: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. If the breaker sits in a warm enclosure near other heat sources, use the 70 °C row for sizing. Operating ambient range is -25 °C to +70 °C; storage range is -40 °C to +80 °C.
Physical Fit and Mounting
Dimensions: 130 mm height, 76.2 mm width (3 inches — fits standard 3-pole MCCB footprint), 70 mm depth. Max power loss is 25 W, so factor that into enclosure thermal calculations. No trip indicator, no undervoltage release, no communication module — this is a straightforward line-protection breaker with a shunt trip for remote open command.
