ge UVH3LP21K 400A 24 V Circuit Breaker

The GE UVH3LP21K is a rugged 400A, 24 V DC circuit breaker designed to safeguard high‑current, low‑voltage DC circuits in demanding environments. Built to interrupt fault currents and protect wiring, feeders, and downstream equipment, this device plays a critical role in keeping power systems reliable and safe.

Key specifications you can rely on

• Current rating: 400 A
• Voltage rating: 24 V DC
• Part number: UVH3LP21K
• Configuration: DC circuit breaker designed for low‑voltage, high‑current applications

Why this 400A, 24V DC breaker is essential

In systems where a 24 V DC supply powers critical equipment, the ability to quickly and reliably interrupt overcurrent is non‑negotiable. The UVH3LP21K delivers robust protection for heavy‑duty DC feeders, reducing the risk of insulation damage, downstream component failure, and electrical fires. Its 400 A rating makes it well suited for main feeds and high‑current branches in industrial panels, solar storage circuits, and other low‑voltage DC distributions.

Ideal use scenarios

• 24 V DC solar storage and battery‑based power systems requiring solid overcurrent protection
• Industrial control panels and electrical enclosures that run on 24 V DC
• Telecom, data center, or remote site power rails where reliable DC protection is critical
• Replacement or upgrade for GE‑ecosystem panels that require UVH3LP21K compliance

What sets it apart

This GE circuit breaker is purpose‑built for DC applications, where arc behavior and interruption dynamics differ from AC systems. With its 400 A capacity and 24 V DC rating, it provides precise, dependable protection for high‑current DC circuits, helping you maintain operational uptime while keeping safety a top priority.

Practical guidance for deployment

• Confirm that your system operates at or below 24 V DC and within the 400 A protection range.
• Use as a primary protection device for heavy DC feeders or as a trusted protective link in modular GE panels or compatible assemblies.
• Keep a replacement UVH3LP21K on hand for quick swaps to minimize downtime after a fault event.

Designed for professionals who manage reliable DC power infrastructure, the GE UVH3LP21K 400A 24 V circuit breaker combines durable construction with essential overcurrent protection — a smart, safety‑conscious choice for your low‑voltage distribution needs.
