Eaton HJD3200L - 200 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Eaton HJD3200L is a 200A, 600V, 3-pole bolt-on molded case circuit breaker built for dependable branch circuit protection in panelboards and loadcenters. With a secure bolt-on mounting and a rugged, vibration-resistant bus connection, this unit delivers consistent protection where it matters most—behind every commercial, residential, or light industrial electrical installation.

Why the HJD3200L Stands Out

• Secure bolt-on mounting: A rigid connection minimizes movement and loosening over time, reducing the risk of degraded contact and heat buildup in demanding environments.
• Thermal-magnetic trip unit: Combines thermal overload protection with magnetic short-circuit protection, delivering stable, repeatable performance across varying loads and temperatures.
• Three-phase, 200A capacity: Ready for three-phase feeders and distribution circuits common in commercial and light industrial setups, while still fitting residential or mixed-use panels that require three poles.
• 600V maximum rating: Suitable for a broad range of panelboard and equipment applications, providing reliable protection where higher voltage circuits are present.
• OEM compatibility: Designed to pair with matching Eaton OEM loadcenters and panelboards for a coordinated protection system and straightforward replacement.

What Problems It Solves

In everyday electrical systems, overcurrent or a developing short can threaten equipment, downtime, and safety. The HJD3200L delivers:

• Immediate isolation of faulted circuits to prevent damage to wiring, devices, and feeders.
• Consistent trip characteristics that minimize nuisance trips and support reliable service continuity.
• A robust mechanical connection that withstands vibration and thermal cycling in dynamic environments.

Installation & Compatibility

Designed to work seamlessly with matching Eaton OEM loadcenters and panelboards, the HJD3200L simplifies replacement and upgrade projects. When selecting this breaker, ensure it matches the panelboard family and that the 3-pole 200A, 600V rating aligns with the system’s design and safety requirements. The bolt-on mounting promotes a tight, durable bus connection, helping maintain optimal electrical performance over the life of the installation.

Practical Tips & Best Practices

• Plan for coordinated protection by pairing the HJD3200L with Eaton-compatible panelboards to ensure consistent trip characteristics and ease of maintenance.
• Inspect mounting hardware and bus connections during installation to confirm a firm, vibration-free fit that preserves contact integrity.
• Use in applications where three-phase protection is required or preferred for balanced loading and device protection in commercial or light industrial settings.

With the Eaton HJD3200L, you’re choosing proven, reliable overcurrent and short-circuit protection built to endure demanding environments while delivering predictable performance across a range of panelboard configurations.
