Information About HF366RA
The HF366RA is part of Siemens’ VBII Series of heavy-duty disconnect switches, engineered for high-performance switching and circuit protection. Designed for three-phase, 60 Hz systems, this fused switch accommodates three Class R fuses and delivers a maximum interrupting capacity of 200 kA at 600V. The visible blade design ensures clear verification of contact separation, while the quick-make, quick-break mechanism guarantees fast and positive switching. Featuring a defeatable dual cover interlock, padlock provisions, and a hook-stick operable red handle, the HF366RA prioritizes operator safety and compliance with NEC wire-bending space requirements. Suitable for both indoor and outdoor use, it is ideal for motor disconnects, service entrance applications, and industrial control systems.
Key Features:
- Heavy-Duty Construction: Type VBII switch built for demanding industrial and commercial environments.
- High Current Rating: 600A, 600VAC for large-scale electrical distribution systems.
- Visible Blade Design: Provides visual confirmation of contact separation for maximum operator safety.
- Double-Break Switching Action: Ensures reliable circuit interruption and extended switch life.
- NEMA 3R Enclosure: Outdoor-rated steel housing protects against dust, rain, and corrosion.
- Quick-Make, Quick-Break Mechanism: Guarantees fast, positive on/off operation under load.
- Padlockable Handle: Accommodates up to three padlocks for secure lockout/tagout compliance.
- Arc Chute Assembly: Efficiently dissipates heat during switching to enhance component longevity.
- Compliant Design: Meets or exceeds NEC wire-bending and clearance requirements.
The HF366RA delivers the safety, durability, and reliability required for critical disconnection and protection in industrial power systems.
