It's designed specifically for the 100 A, 160 A, and 250 A frame sizes of that breaker family. The stored-energy design means a spring is charged by the motor, then released to toggle the breaker contacts. This gives consistent make and break times of 0.08 s regardless of fluctuations in the control supply voltage — important when coordinating upstream-downstream tripping in a selective scheme. ## Control supply and power draw The operator accepts a control supply of 42 V to 60 V, both AC (60 Hz) and DC — a single part number covers both supply types across that range, which simplifies stocking for panels that mix control voltages. The operating apparent power is 300 VA, so size the control transformer accordingly; a 500 VA transformer is a common safety margin for this draw plus auxiliary loads. At 105 mm wide, 118.7 mm tall, and 162.8 mm deep, this operator mounts directly onto the 3VA2 breaker — no additional DIN-rail footprint beyond the breaker itself. The stripped-length spec of 7 mm on the control wiring terminals matches standard ferrule length for 1.5 mm² to 2.5 mm² stranded conductors. The 60 V maximum control supply is the absolute limit — do not exceed it even momentarily, as the internal electronics and charging circuit are not rated above that.","metaTitle":"Siemens 3VA9267-0HC20 SENTRON SEO Motor Operator, 42-60 V AC","metaDescription":"Siemens SENTRON 3VA9267-0HC20 SEO motorized operating mechanism for 3VA2 100/160/250 breakers. 42-60 V AC/DC control supply, 300 VA.
