CHB380 | Circuit Breaker | 3-Pole | 240V | 10kA | Bolt-On

CHB380 is a rugged 3-pole circuit breaker designed for industrial panels, delivering reliable protection for 240V systems with a 10kA interrupting capacity. It's built for maintenance, retrofit, and replacement projects where precise compatibility matters.

Key specifications

• Poles: 3-Pole
• Voltage: 240V
• Breaking capacity: 10kA
• Mounting: Bolt-On
• Reference: Part number CHB380 ensures alignment with compatible enclosures

Why choose CHB380 for your panel upgrade

When your goal is a quick, field-ready replacement or a seamless retrofit, the CHB380's bolt-on design minimizes wiring changes while delivering solid three-phase protection. This breaker is ideal for upgrading aging gear in 3-phase 240V circuits, helping to reduce downtime and maintain system reliability.

Use cases and applications

• Maintenance replacements in industrial control panels that previously used CHB380-compatible bolt-on breakers
• Retrofits to modernize older equipment with a 3-pole, 240V protection scheme
• New installations in compatible enclosures where a 3-phase, 240V breaker with 10kA capacity is required

Installation and compatibility tips

Before ordering, confirm fit and ratings using the CHB380 part number as the best compatibility reference. Ensure your enclosure accepts bolt-on breakers of this pole count and voltage, and follow standard electrical safety practices during installation. If you're replacing an existing unit, have the enclosure’s mounting hardware ready and verify that the bus bar configuration aligns with a 3-pole, 240V setup.
