Information About DH324NRK
The DH324NRK is part of Eaton’s heavy-duty safety switch series engineered for high-performance power isolation and circuit protection. This fusible disconnect switch uses Class H cartridge fuses to provide overcurrent protection while enabling manual switching of electrical circuits. The unit incorporates a visible double-break rotary blade mechanism that ensures positive opening and closing of contacts while improving durability and contact life. Designed for service entrance installations and outdoor environments, the switch features a painted galvanized steel enclosure with a NEMA 3R rating to protect internal components from weather exposure.
Key Features:
- 200 Amp Current Rating: Supports medium-capacity electrical circuits in commercial and industrial installations.
- Fusible Safety Switch Design: Provides overcurrent protection through installed Class H cartridge fuses.
- Three-Pole, Four-Wire Configuration: Designed for systems requiring a solid neutral connection.
- NEMA 3R Weather-Resistant Enclosure: Suitable for indoor and outdoor installations exposed to rain or moisture.
- Visible Double-Break Blade Mechanism: Ensures clear visual confirmation of circuit disconnection and improved contact performance.
- Padlockable Handle Design: Allows multiple padlocks for increased personnel safety during maintenance.
- Door Interlock Safety Feature: Prevents opening the enclosure when the switch is in the ON position.
- Service Entrance Capability: Designed for use in service entrance applications with proper configuration.
The DH324NRK delivers the reliability and precision required for safe circuit isolation and overcurrent protection in electrical distribution systems.
