Industrial LA3100PT 100A 3-Pole 600 V Circuit Breaker Potential Transformer is a purpose-built solution for reliable three‑phase protection and precise metering in demanding industrial environments. Built to handle the rigors of heavy electrical systems, this unit combines a robust 100 A circuit breaker with a built‑in potential transformer, delivering safe, scalable signaling for protection relays and power monitoring equipment.

Why the LA3100PT stands out

• Three‑pole design for balanced three‑phase protection—ensures synchronized switching and consistent fault isolation across L1, L2, and L3 in 3‑phase circuits.
• 100 A current rating supports common industrial feeders and motor circuits, providing dependable protection for equipment and personnel.
• 600 V voltage rating aligns with industrial distribution standards, enabling compatibility with a wide range of equipment and panel configurations.
• Integrated potential transformer (PT) delivers a scaled, safe signal to protection relays and meters, reducing wiring complexity and improving signal integrity for accurate fault detection and power quality monitoring.
• Compact, single‑unit solution minimizes panel footprint and simplifies installation by combining protection and metering signaling in one component.

Who benefits from the LA3100PT

This device is ideal for:

• Industrial facilities with three‑phase feeders—manufacturing lines, processing plants, and heavy tooling environments.
• Electrical panels and subpanels requiring reliable protection with convenient metering inputs for relays and instrumentation.
• Data centers, cold storage, and facilities where precise monitoring and rapid fault isolation are critical to uptime and safety.
• retrofit projects where reducing wiring and integration time is a priority without sacrificing protection standards.

How it solves real-world problems

With the LA3100PT, you gain:

• Reduced installation complexity—the built‑in PT streamlines wiring to relays and meters, cutting installation time and potential wiring errors.
• Improved protection accuracy—the PT provides clean, proportional signaling for relay inputs, helping guards respond faster to faults and anomalies.
• Enhanced system visibility—integrated metering signals enable better monitoring of current draw, allowing proactive maintenance and energy-management insights.

Practical guidance for use

For optimal results with the LA3100PT:

• Connect the three line terminals to the three‑phase supply and tie the neutral or ground references as required by your panel design.
• Route the potential transformer secondary to compatible protection relays or metering inputs, ensuring polarity and ratios align with protection schemes.
• Verify torque specifications on all terminations and inspect for secure connections to prevent arcing and downtime.
• Label the device clearly as LA3100PT to simplify future maintenance and audits, and maintain documentation for relay compatibility and PT ratios.
