SF3C100 | Circuit Breaker | 3-Pole

SF3C100 is a robust 3-pole circuit breaker built for demanding industrial environments where protection must be precise and downtime minimized. Designed with maintenance, retrofit, and replacement projects in mind, this device offers a like-for-like path to restore reliable three-phase protection without rewriting panel layouts or wiring schematics. Note: Confirm fit and ratings before ordering. Part number SF3C100 is the best reference for compatibility, ensuring you match the exact pole count, mounting footprint, and trip characteristics your system requires.

Three-pole protection for three-phase systems

This SF3C100 device delivers coordinated protection across all three phases, helping safeguard motors, drives, and other three-phase equipment. By maintaining synchronized trip behavior, it reduces the risk of unbalanced faults that can stress equipment and cause unintended shutoffs.

Why it matters in the field

• Drop-in replacement: Designed to align with common industrial panel configurations so you can swap in without extensive rewiring.
• Consistent protection: Keeps the same interruption and trip performance you rely on, preserving system safety and uptime.
• Long-term reliability: Built for industrial use where ongoing protection and predictable operation are essential.

Ideal use cases

• Maintenance: Replace aging or failed breakers to restore full circuit protection quickly.
• Retrofit: Upgrade legacy systems to modern protection devices while preserving existing voltages and current ratings.
• Replacement stock: Keep SF3C100 on hand as a standard, compatible component for service contracts and routine spares.

Pre-purchase checklist

• Poles: 3-Pole (as described) to match your three-phase circuit.
• Ratings: Verify the current and voltage ratings align with your panel and load requirements.
• Mounting and terminals: Confirm the device’s mounting style and terminal configuration fit your enclosure and wiring setup.
• Trip characteristics: Ensure the trip curve meets the protection needs of your equipment and control logic.

How SF3C100 compares to typical replacements

Unlike generic substitutes, SF3C100 is specified to align with established industrial panels and three-phase protection schemes. By sticking to the exact part number, you minimize compatibility risks, maintain consistent electrical clearance and bus interface, and reduce downtime during replacements or upgrades.

For technicians and engineers, choosing SF3C100 means predictable serviceability, straightforward ordering, and a clear reference point for future replacements. If your system relies on a 3-pole industrial breaker with matching specs, SF3C100 offers a reliable, well-supported option that keeps your electrical infrastructure running smoothly.
