The ABB 2CDS273317R0337 is a SACE Tmax series Molded Case Circuit Breaker (MCCB) from the Miniature Circuit Breakers (MCB) category. 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.
What the ratings mean for the panel
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.
