SCCR Documentation for Control Panels
Short-circuit current rating (SCCR) is an important consideration when engineering an industrial control panel for the North American market. Per NEC 409.110, the SCCR of the overall panel is affected by the components and configuration used within the control panel.
SCCR documentation is developed based on the selected components, protective devices and panel configuration. The engineering process may require review of:
- Overcurrent protective devices
- Branch circuit components
- Power supplies
- Motor starters and contactors
- VFDs and servo drives
- Control transformers
- Busbars
- Terminal blocks
- Disconnects
- Manufacturer component ratings
- Combination ratings where applicable
Riches PowerTech does not assign an SCCR value simply for marketing purposes. The final SCCR should be supported by the applicable engineering calculation, component documentation and project requirements.
UL Listed and UL Recognized Components
Our industrial control panels may incorporate UL Listed or UL Recognized components from major manufacturers. Component selection is based on the project specification and applicable requirements.
NEMA 1
Suitable for many indoor industrial and commercial applications where protection against accidental contact and limited environmental exposure is required.
NEMA 3R
Used for applicable outdoor installations where protection against rain and environmental exposure is required.
NEMA 4 / 4X
Watertight enclosures for washdown applications, food processing, and corrosive environments. NEMA 4X uses stainless steel or fiberglass construction.
NEMA 12
Indoor dust-tight enclosures for industrial environments where protection against dust, lint, and fibers is required.
