Eaton HJD3070 - 600 V, 3-Pole Circuit Breaker | AmpState

Overview

Designed by Eaton for dependable protection, the HJD3070 is a 3-pole molded case circuit breaker rated at 600 V. It provides reliable branch-circuit overcurrent and short-circuit protection in panelboards and load centers, helping you build safer electrical systems for residential, commercial, and light industrial applications.

Key Features

• Compact molded case design optimizes panel space, making it easier to fit into tighter installations without sacrificing protection.
• Thermal-magnetic trip unit delivers stable, repeatable protection: the thermal element protects against long-term overcurrent, while the magnetic element provides instantaneous response to short circuits.
• OEM-compatible fit is designed to work with matching Eaton OEM load centers and panelboards for a seamless, reliable integration.
• Versatile for multiple sectors suitable for residential, commercial, and light industrial electrical protection needs.

Technical Specifications

• Manufacturer: Eaton
• Part Number: HJD3070
• Type: Thermal-magnetic molded case circuit breaker
• Voltage Rating: 600 V
• Number of Poles: 3
• Application: Branch circuit overcurrent and short-circuit protection

Ideal Use Scenarios

• Upgrading or configuring panelboards and load centers in residential renovations or new-build projects that require robust 3-pole protection.
• Protecting three-phase or multi-wire branch circuits in light commercial environments and small industrial setups where reliable short-circuit response is critical.
• Scenarios where OEM compatibility with Eaton load centers ensures consistent performance and straightforward replacement or expansion.

Why This Breaker Stands Out

Beyond basic protection, the HJD3070 emphasizes efficiency and reliability in real-world conditions. The molded case design minimizes space while maintaining durable construction, and the thermal-magnetic trip unit provides a balanced protection profile that you can trust across a range of loads and fault conditions. Its compatibility with matching OEM panelboards means fewer compatibility concerns and faster, cleaner installations.

Practical Tips for Best Results

• Match the HJD3070 to a compatible OEM load center to ensure proper mounting, electrical clearance, and trip coordination within the panel.
• Install per NEC guidelines and the panelboard manufacturer’s instructions to ensure correct protection settings and safe operation.
• Use in applications where a single device protects multiple conductors in a three-pole configuration to maintain balanced protection across phases.
