It's a 3-pole unit with a full-scale current rating of 63 A, and it carries an overload setting range from 95 A minimum to 756 A maximum, so the trip threshold is field-adjustable across a wide band to match the downstream conductor ampacity.
At 240 V it's rated for 187 kA — that's a very high figure, typical for a large-frame MCCB feeding a main switchboard or a high-fault industrial panel. At 415 V and 440 V it holds at 121 kA, then drops to 75.6 kA at 500 V, and falls off sharply to 3.7 kA at 690 V.
Thermal rating — flat across the operating range
That's unusual for an MCCB; many competitors start derating above 40 °C. Maximum power loss is 4 W, which is low enough that ventilation spacing in the panel is not a concern for this breaker alone.
Auxiliary and communication options
It also includes a communication function via a plug-in module.
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard 3-pole MCCB footprint that fits most Siemens SENTRON distribution panels and third-party enclosures with a 105 mm cutout. The depth of 86 mm means it will clear a typical 200 mm deep enclosure door without interference.
