Why a 2-pole, 600 V breaker matters

This two-pole design protects both conductors in a typical 240 V circuit, ensuring simultaneous disconnection during a fault. The 600 V rating expands its applicability to higher-voltage distributions where safety and rapid isolation matter most. Built by Square D, a trusted name in electrical protection, this breaker is engineered to perform consistently under demanding conditions.

Ideal use cases

• Mid-range branch circuits in commercial or light industrial panels that require 35 A protection.
• Replacement in sistemas that specify the HJA260351 part number for compatibility and reliable operation.
• Motor, heater, or equipment feeders where dual-hot protection is essential for safety and code-compliant isolation.
• Panels and enclosures that serve higher-voltage distributions within permitted 600 V applications.

What sets this apart from similar breakers

• Direct compatibility: Specifically identified as HJA260351, reducing guesswork during replacement or panel upgrades.
• Balanced protection: The two-pole design ensures both lines clear faults together, minimizing risk to adjoining equipment and improving overall circuit safety.
• Industry-grade reliability: Backed by Square D’s longstanding reputation for protective devices in panels and feeders.

Practical tips for installation and use

• Verify that your panel requires a 2-pole, 600 V-rated device and that the format matches HJA260351 before installation.
• Consult your panel labeling and manufacturer guidelines to ensure proper mounting, alignment, and replacement procedure.
• Use this breaker for new builds or refurbishments where a 35 A protection level on a dual-hot circuit is needed, balancing safety with performance for connected loads.
