What the 200 A continuous rating means for your panel
The 3VA2220-7MN32-0KL0 is a Siemens SENTRON molded case circuit breaker (MCCB) built for motor protection duty. Its headline number is the 200 A continuous rating — and the key here is that it holds that 200 A flat from 40 °C all the way up to 70 °C ambient. That means no derating curve to chase when the panel runs hot; the breaker delivers its full nameplate current across the operating range it's likely to see in a real enclosure. Rated for three-pole switching, it carries a 330 kA breaking capacity at 240 V, stepping down to 242 kA at 415 V and 440 V, then 187 kA at 500 V, and 5.2 kA at 690 V — numbers that tell you this MCCB is sized for high-fault industrial distribution, not light commercial service.
Motor protection features and auxiliary options
This MCCB is specifically designed for motor protection, which means its trip curve is shaped to handle inrush without nuisance tripping while still clearing a locked-rotor fault. It includes phase failure detection — a critical feature for three-phase motor circuits where losing one phase can burn out a winding before the overload relay notices. The breaker ships with a shunt trip release (STL) for remote emergency-off or supervisory tripping, plus a full auxiliary switch complement: 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ). That gives you status feedback for both the breaker position and the trip event. The basic switch assembly carries its own order code 3VA2220-7MN32-0AA0 if you ever need to reference the core switching unit separately.
Physical fit and panel integration
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep. That 86 mm depth is the dimension to watch when sizing the enclosure depth — it dictates the clearance needed behind the panel door for the breaker body and wiring gutters. The 105 mm width is the DIN-rail footprint for a 3-pole frame of this class. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C. Maximum power dissipation is 46 W — a figure to factor into enclosure thermal calculations if the panel is densely packed.
