Breaking capacity and thermal derating
The 3VA1110-5EF36-0BC0: The 187 kA at 240 V is the highest interrupting rating on this breaker; at 415 V it drops to 121 kA, at 440 V to 75.6 kA, and at 690 V to 17 kA. Above that, derating applies: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C.
Fit and integration
The 3VA1110-5EF36-0BC0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a compact footprint for a 100 A MCCB. It is designed for panel mounting, not DIN rail; the width matches the standard SENTRON 3VA base frame.
