At 400 V AC the breaking capacity drops to 25 kA Icu, so if your distribution system runs at 400 V line-to-line, that's the figure to coordinate with upstream protection. The TM-D trip unit provides fixed long-time delay at 1 In and a fixed magnetic pickup at 500 A (10× In). That means the breaker is set for general distribution loads — no field-adjustable thermal or magnetic settings. For motor branch circuits requiring adjustable overloads, a different trip unit or a separate motor-protective breaker would be needed.
Deployment context
This MCCB mounts fixed to a backplate with front-connect terminals — no DIN-rail clip. The 25 mm pole pitch and 75 mm width fit standard panel cutouts for 3-pole molded-case breakers.
The IK07 impact rating means it withstands a 2 J hammer blow, typical for panel-mounted gear.
