Mounts on the top or bottom of a compatible circuit breaker via screw terminals, with a 0.25 m flying lead terminated in a 1 x 0.33 mm² cable. The sensor element measures 44.5 mm deep by 18 mm wide by 20 mm high — compact enough to fit in a crowded DIN-rail enclosure without blocking adjacent breaker toggles. Rated IP20 with IK05 impact protection, so it's suited for dry indoor switchboard environments where accidental tool contact is the main risk.
The 63 A maximum current (Imax) and 130 A saturation current define the measurement range: the sensor stays linear up to 63 A and can survive short-duration overloads up to 130 A without damage. Supply voltage is 100...125 V AC ±20 %, 50/60 Hz, drawing a starting current of 40 mA and a maximum power consumption of 1 VA — negligible load on the control transformer.
Carries CE marking under the Radio Equipment Directive 2014/53/EU and complies with IEC 61557-12, IEC 61010-1, IEC 61010-2-030, IEC 61326-1, ETSI EN 300 328, and ETSI EN 301 489-1 — covers both measurement accuracy and wireless coexistence. Rated for operating altitude up to 2000 m and relative humidity 0...95 % at 45 °C per IEC 60721-3-3, with vibration resistance 3M4.
