Specifications
IMO 55A SI55-PEL64R-4 Enclosed DC Switch 4 Pole 600Vdc
Special Features
- True DC Isolation: Designed specifically for DC isolation in solar PV systems, providing reliable protection against arcing and ensuring safety in high-voltage environments.
- High Current and Voltage Rating: Supports up to 55A and 1500V DC, suitable for a wide range of solar installations.
- Compact, Enclosed Design: Rated for IP66 (front panel) and NEMA 4X, offering robust environmental protection in harsh outdoor conditions.
- Safe-Lock Handle: Patented handle design offers three positions (ON-OFF-LOCK), preventing unauthorized access and enhancing safety during maintenance.
Technology Overview
The IMO SI55-PEL64R-4 is built to withstand the demands of DC switching, utilizing a rotary “knife contact” mechanism to ensure fast arc suppression (3 ms typical) and minimal wear. The isolator is fully compliant with EN 60947-3 and UL508i standards, making it suitable for PV systems requiring high-reliability switching and isolation.
Installation
The isolator is designed for ease of installation with a panel mount (64x64 mm escutcheon plate) and lockable rotary handle. It is polarity-independent, allowing for flexible wiring configurations in DC applications.
Applications
- Solar PV Installations: Ideal for residential and commercial solar setups, where high DC voltage and current ratings are essential.
- Safety and Compliance: Suitable for systems requiring compliance with UL and IEC standards for reliable, secure DC isolation.
