Key specifications at a glance

• Amperage: 90A
• Poles: 3-Pole
• Voltage: 600V
• Part number: RK3090L

Why choose the RK3090L for your panel

The RK3090L is designed for maintenance, retrofit, and replacement scenarios where exact compatibility matters. Its three‑pole configuration protects all conductors in a three‑phase circuit, ensuring synchronized tripping and safer fault isolation across the system. This makes it an ideal fit for panelboards and switchgear that require a consistent 3‑pole, 600V protection device with a clear, proven reference part number.

How this helps in real-world use

• Retrofit made simple — when upgrading older panels, the RK3090L aligns with common form factors and ratings, reducing installation guesswork.
• Reliable protection for three‑phase loads — simultaneous interruption across all three hot legs minimizes arc faults and equipment damage.
• Maintenance and service efficiency — clear part number reference (RK3090L) streamlines ordering and compatibility checks for field technicians.
• Versatile installation contexts — suitable for commercial equipment, electrical rooms, and retrofit projects where 90A protection is appropriate at up to 600V.

Compatibility and installation tips

Before ordering, confirm fit and ratings for your specific panel or switchgear. The part number RK3090L serves as the best reference for compatibility, so match it to your panel label and manufacturer's documentation to ensure a drop‑in replacement or seamless retrofit.
