ITE | HJ3B175 | Circuit Breaker | 175A | 3-Pole | 600V | 65kA | Bolt-On

The ITE HJ3B175 Circuit Breaker is a bolt-on, 3-pole protective device built for demanding 600V electrical systems. With a 175A rating and a 65kA interrupting capacity, it delivers solid, reliable overcurrent protection for motor feeders, panel boards, and three-phase distribution in industrial and commercial environments.

• Amperage: 175A
• Poles: 3-Pole
• Voltage: 600V
• Interrupting rating: 65kA
• Mounting: Bolt-On
• Part number reference: HJ3B175

Key benefits come from its bolt-on design, which provides a secure, vibration-resistant fit in compatible enclosures. The 600V rating makes it suitable for a wide range of mid- to high-voltage distribution applications, while the 3-pole configuration ensures synchronized protection across all phases of a 3-phase system. The 65kA interrupting capacity offers stronger fault-current handling, helping to minimize damage during short-circuit events and protect downstream equipment.

Compatibility and use cases

• Maintenance and retrofits where exact specifications are required.
• Replacement in existing panels that call for HJ3B175 or equivalent 3-pole, 600V protection.
• Industrial and commercial power distribution upgrades that demand reliable, long‑lasting circuit protection.

Important compatibility note: Confirm fit and ratings before ordering. The part number is the best reference for compatibility.

Practical installation tips

• Ensure the enclosure supports bolt-on breakers and is rated for 600V systems.
• Verify bus bar alignment and that the enclosure accommodates a 3-pole device.
• Keep a spare HJ3B175 on hand for planned replacements to minimize downtime.

Designed for electricians and panel technicians focused on dependable three-phase protection, the ITE HJ3B175 is a concrete, specification-driven choice for upgrade projects, retrofits, and in-kind replacements in demanding electrical environments.
