Information About H221NRB
The H221NRB is part of the Square D F Series heavy duty safety switches manufactured by Schneider Electric for industrial and commercial power applications. It exceeds the mechanical endurance requirements of NEMA KS-1 and UL 98 standards, ensuring long-term durability under frequent operation. The switch features a dual cover interlock and a color-coded handle to provide clear visual indication of switch status and prevent unsafe access during operation. It is commonly installed as a service or equipment disconnect where robust construction, fusible protection, and weather-resistant enclosures are required.
Key Features
- Heavy duty fusible disconnect: Designed for high-reliability isolation and overcurrent protection.
- Quick-make, quick-break mechanism: Ensures fast and positive circuit opening and closing.
- Square D F Series design: Built to exceed NEMA KS-1 and UL 98 mechanical endurance standards.
- Dual cover interlock: Prevents enclosure access while the switch is in the ON position.
- NEMA 3R enclosure: Provides protection for outdoor installations exposed to rain and sleet.
- Color-coded handle: Offers clear visual indication of switch status.
- Wide SCCR capability: Supports high short-circuit current ratings with appropriate fuses.
The H221NRB delivers the reliability and precision required for heavy duty electrical disconnect applications in outdoor and industrial environments.
