JB3100W | Circuit Breaker | 100A | 3-Pole | 600V

The JB3100W circuit breaker is an industrial-grade protection device designed for maintenance, retrofit, and replacement tasks where exact specifications matter. With a 100A rating, 3-pole configuration, and a 600V rating, it's built to safeguard three-phase electrical systems while minimizing downtime.

Key specifications

• Amperage: 100 A
• Poles: 3-Pole (three-phase protection)
• Voltage: 600 V

What makes the JB3100W unique

• Direct-fit compatibility for scenarios requiring exact specifications; the part number JB3100W is the most reliable reference when matching equipment
• Three-pole design ensures balanced protection across all phases, reducing the risk of uneven loading in industrial circuits
• Engineered for retrofit and replacement workflows, helping you swap in a like-for-like protector quickly and minimize downtime
• Clear fit-and-rating guidance: before you order, verify the fit and ratings in your panel or switchgear to ensure seamless operation

Who should consider this breaker

Maintenance teams, panel builders, and OEMs working with 600V three-phase distribution will benefit from a reliable, direct-replacement device that aligns with existing gear. If your system requires a 100A feed across three phases, the JB3100W is purpose-built for that duty.

Use cases and practical tips

• Replacement in aging control panels where the existing breaker matches a 100A, 3-Pole, 600V profile
• Retrofits where you need to upgrade to a 600V three-phase protection without reconfiguring wiring or bus bars
• Spare on hand for rapid restoration after a fault or during maintenance windows

Note: Confirm fit and ratings before ordering. The JB3100W part number serves as the best compatibility reference to ensure you’re selecting the exact device your system requires.
