FAQs
This model uses a three-pole enclosure rated for 600 V and 200 A, with dimensions of 21 in depth, 15.74 in width, and 14.04 in height. Plan for adequate front clearance for the pistol-handle and safe lockout/tagout access, and ensure mounting supports the NEMA 3R enclosure in the intended environment. Verification of panel space and fuse integration with CF/CST types is recommended during commissioning.
The switch is rated for 600 V AC, 200 A, with a three-pole configuration and a NEMA 18 electrical rating inside a NEMA 3R enclosure. These ratings support typical industrial control and motor control center applications, offering safe isolation for high power loads and robust fault protection in harsh environments.
Yes, the unit is CE Marked, indicating conformity with applicable health, safety, and environmental requirements in many regions. This makes it suitable for international projects where CE compliance is a purchase criterion, while local electrical standards should still be verified for site-specific installation.
The ER3R-200CF3PR-CST supports fuse types CF and CST. This compatibility enables straightforward integration with Bussmann fuse products, simplifying spare parts management and ensuring consistent overcurrent protection within existing protection schemes.
The enclosure provides rugged, safe isolation with a pistol-handle design for rapid de- energization, reducing maintenance downtime and improving safety during service. Its CF/CST fuse compatibility and standard 600 V/200 A ratings support reliable protection, ease of integration with Bussmann components, and scalable panel protection for growing production lines, ultimately lowering total cost of ownership.
