Meet the Square D EHB340301082 Circuit Breaker — a precise, rugged solution for 480V, 3-phase power distribution. With a 30A rating and a 3-pole bolt-on design, this device is engineered for maintenance, retrofit, and replacement tasks where exact specifications matter. The part number EHB340301082 is the strongest reference for compatibility, so verify fit and ratings before ordering to ensure a secure installation.

Key specifications

• Amperage: 30A
• Poles: 3-Pole
• Voltage: 480V
• Mounting: Bolt-On
• Part number: EHB340301082

Why this bolt-on, 3-pole breaker is the right choice

This breaker is purpose-built for environments where 480V, three-phase power is the norm. The bolt-on mounting provides a secure, mechanically robust connection suitable for vibration-prone industrial settings, while the 3-pole design ensures simultaneous disconnection of all hot conductors, enhancing overall safety during trips and maintenance. Because it’s a precise match for systems that require the EHB340301082 specification, it’s especially valuable for retrofits and replacements in panels that rely on bolt-on protection devices.

Ideal use cases

• Retrofit projects in industrial panels that require a 30A, 3-pole, 480V bolt-on breaker
• Maintenance replacements for failed or worn 480V 3-phase protection devices
• New equipment installations in facilities with 480V power distribution, where a specific bolt-on configuration is needed

Buying and installation guidance

• Confirm compatibility by matching your equipment’s required part number and mounting type—EHB340301082 is the authoritative reference for fitment.
• Ensure the panel or switchgear supports bolt-on breakers of this size and voltage class.
• Prepare for installation by verifying torque specs and adherence to panel manufacturer guidelines to maintain safe, reliable operation.

What sets it apart from generic options

This device isn’t a one-size-fits-all solution. It’s a precise match for Square D systems that demand a 30A, 3-pole, 480V bolt-on breaker. Its specific configuration, paired with the exact part number, reduces the guesswork in maintenance and retrofit projects and helps protect critical 480V circuits with the intended protection characteristics.

Care, handling, and best practices

• Store and handle in clean, dry conditions to preserve contact integrity and mounting hardware
• When installing, follow panel-specific instructions and ensure proper seating and secure mounting to prevent arcing or loose connections
• Keep the part number readily available for future replacements or ordering consistency
