It is designed for branch circuit protection in industrial and commercial power distribution panels, rated for the thermal-magnetic trip curve typical of the Tmax platform. The unit weighs 1.36 kgs, which sets the handling and DIN-rail or mounting-plate load expectation for the panel builder.
The 1.36 kgs mass tells the panel builder to account for the breaker's weight in the mounting structure — a standard DIN rail with end stops handles it, but a vertical bus stack may need additional support brackets. As an MCCB, the interrupting rating and continuous current capacity are defined by the Tmax frame size; the 2CDS273317R0337 order code locks in the specific thermal-magnetic trip unit and pole configuration. No auxiliary contact or shunt trip is included in this base order code — those are separate add-on accessories that clip onto the Tmax side profile.
