Westinghouse | JDC3100 | Circuit Breaker | 100A | 3-Pole | 600V | 22kA | Bolt-On

Meet the Westinghouse JDC3100—a dependable three-pole circuit breaker engineered for reliable overcurrent protection in industrial and commercial panels. With a 100A rating, 600V capacity, and a bolt-on design, this unit is built for straightforward maintenance, retrofit, and replacement projects where precise specifications matter.

• Amperage: 100A
• Poles: 3-Pole
• Voltage: 600V
• Interrupting Rating: 22kA
• Mounting: Bolt-On

Why the JDC3100 stands out

Designed with practicality in mind, this Westinghouse breaker simplifies upgrades and replacements without sacrificing performance. The bolt-on mounting speeds up service calls, helping technicians swap units quickly while maintaining solid, secure connections. The 3-pole configuration ensures balanced protection across all phases, which is essential for three-phase systems common in commercial and light industrial equipment. A 22kA interrupting rating provides enhanced fault energy handling, contributing to safer shutdowns during overloads or short circuits.

Ideal use cases

• Maintenance and retrofit of existing three‑phase distribution panels
• Replacement for worn or obsolete breakers in commercial facilities
• Panel upgrades where exact specifications (100A, 600V, 3-Pole, bolt-on) are required
• New installations that demand a reliable, industry-standard protection device

Key compatibility notes

To ensure correct fit, rely on the part number JDC3100 as the primary reference for compatibility. Before ordering, confirm that the ratings align with your panel’s requirements and that the bolt-on mounting matches your enclosure. This approach minimizes downtime and ensures a trouble-free installation that complements existing protection schemes.

Practical tips for deployment

• Verify wiring diagrams and torque specifications for the bolt-on terminals to ensure a secure, code-compliant connection.
• Coordinate with your maintenance plan to schedule a controlled shutdown when replacing an existing unit—this minimizes process interruptions.
• Keep a reference chart of your panel’s breakers and cross-check with the JDC3100’s ratings to preserve system balance.
• Store spare units in a clean, dry environment to preserve terminal integrity and labeling clarity for future service needs.
