LRELL4X48PG 48A 4P Circuit Breaker | AmpState

LRELL4X48PG is a 48 A, 4-pole circuit breaker chosen for dependable circuit protection in panelboards, load centers, and broader electrical distribution networks. This part is especially valuable for retrofit work and maintenance planning where keeping the exact part number consistent simplifies ordering, records, and service history.

Why this 4-pole 48 A breaker stands out

• Four-pole design supports multi-wire or 3-phase circuits, delivering coordinated protection across all conductors.
• 48 amp rating provides targeted protection for medium-load branch circuits, helping prevent overcurrent events without unnecessary interruptions.
• Designed to integrate with standard panelboard and load-center footprints, preserving mounting alignment and compatibility with existing enclosures.
• Part-number stability makes this model ideal for retrofit projects and long-term maintenance plans where procurement consistency matters.
• AmpState offers availability and expert help to verify fit and compatibility, reducing guesswork during replacements.

Ideal for who and where

• Facilities managers and electricians tackling retrofits or panel updates who need a reliable, version-stable component.
• Maintenance planners building stock for predictable maintenance windows with minimal downtime.
• Systems engineers protecting multi-wire and three-phase distribution networks where a cohesive, four-pole solution is required.

Practical use cases

• Replacing a failed 4-pole breaker in an aging panelboard to restore protected loads quickly.
• Adding a ready-to-go spare in facilities with critical distribution circuits that cannot tolerate extended outage times.
• Retrofits where panel specifications call for a specific LRELL4X48PG part number to maintain documentation and compatibility across maintenance cycles.

How it supports safer, more reliable electrical distribution

By delivering coordinated protection across all lines in multi-wire and three-phase configurations, this breaker helps prevent nuisance trips and ensures that protective devices operate in harmony during fault conditions. Its alignment with standard panel and load-center designs minimizes retrofit headaches and simplifies future service planning.
