Standards and Notes
10.10 Temperature rise: The panel builder is responsible for the temperature rise calculation. Eaton will provide heat dissipation data for the devices.
10.11 Short-circuit rating: Is the panel builder’s responsibility. The specifications for the switchgear must be observed.
10.12 Electromagnetic compatibility: Is the panel builder’s responsibility. The specifications for the switchgear must be observed.
10.13 Mechanical function: The device meets the requirements, provided the information in the instruction leaflet (IL) is observed.
10.2.2 Corrosion resistance: Meets the product standard’s requirements.
10.2.3.1 Verification of thermal stability of enclosures: Meets the product standard’s requirements.
10.2.3.2 Verification of resistance of insulating materials to normal heat: Meets the product standard’s requirements.
10.2.3.3 Resistance of insulating materials to abnormal heat/fire by internal electrical effects: Meets the product standard’s requirements.
10.2.4 Resistance to ultra-violet (UV) radiation: Meets the product standard’s requirements.
10.2.5 Lifting: Does not apply, since the entire switchgear needs to be evaluated.
10.2.6 Mechanical impact: Does not apply, since the entire switchgear needs to be evaluated.
10.2.7 Inscriptions: Meets the product standard’s requirements.
10.3 Degree of protection of assemblies: Does not apply, since the entire switchgear needs to be evaluated.
10.4 Clearances and creepage distances: Meets the product standard’s requirements.
10.5 Protection against electric shock: Does not apply, since the entire switchgear needs to be evaluated.
10.6 Incorporation of switching devices and components: Does not apply, since the entire switchgear needs to be evaluated.
10.7 Internal electrical circuits and connections: Is the panel builder’s responsibility.
10.8 Connections for external conductors: Is the panel builder’s responsibility.
10.9.2 Power-frequency electric strength: Is the panel builder’s responsibility.
10.9.3 Impulse withstand voltage: Is the panel builder’s responsibility.
10.9.4 Testing of enclosures made of insulating material: Is the panel builder’s responsibility.
