SENTRON 3VA1040-3ED36-0KH0 — 40 A MCCB for Line Protection
It carries a 75.6 kA breaking capacity at 240 V and 52.5 kA at 415 V, which means it safely interrupts high fault currents without cascading upstream — critical for selectivity coordination in a main or feeder breaker position.
Breaking Capacity and Thermal Performance
Breaking capacity is rated at 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. Thermal current rating holds at 40 A from 40 °C through 50 °C, then derates to 38.4 A at 55 °C and 36 A at 70 °C.
Auxiliary Circuit Configuration and Release Options
No undervoltage release is fitted, so the breaker does not drop out on voltage sag; if UVR protection is needed, select a different suffix. The trip indicator and voltage trigger are present, confirming visual and electrical trip indication.
The 76.2 mm width matches the 3-pole modular pitch for SENTRON 3VA breakers, so it occupies three 25.4 mm (1-inch) module spaces.
