SIRIUS 3RV1364-7AN10 — 100 A MCCB for Starter Combinations
The short-circuit trip is electronic, which gives more precise coordination with downstream contactors and overload relays compared to thermal-magnetic designs.
The breaking capacity varies by line voltage: 100 kA at 240 V AC, 200 kA at 400 V AC, 150 kA at 500 V AC, and 80 kA at 690 V AC. At 690 V, the 80 kA rating still covers most heavy industrial applications. The AC-3 operational current at 400 V is 100 A, matching the continuous rating — so the motor load and the breaker rating align without derating for typical induction motor starting duty.
Environmental and Installation Constraints
Shock resistance is 12 g for 11 ms, which is standard for industrial panel mounting. Maximum installation altitude is 2,000 m above sea level — above that, dielectric strength and current-carrying capacity derate per IEC 60947. The main and auxiliary/control circuits both use screw-type terminals, so expect to torque per the manufacturer's spec on the nameplate. The breaker accepts auxiliary switch modules, but this base unit ships with zero built-in contacts — you add what the circuit needs.
