The Eaton PLSM series is a complete line of modular overcurrent circuit breakers designed for modern electrical distribution panels. Built for professional electricians, this series delivers dependable protection for residential and commercial projects. Whether wiring a new building or upgrading a panel, PLSM breakers provide safety without unnecessary complexity.

Wide Range of Modular Circuit Breakers

The PLSM lineup covers common circuit protection needs. You will find single-pole, double-pole, and triple-pole options with ratings from 6A to 40A. The series includes both B and C trip characteristics, giving you flexibility to match the breaker to your load. B-curve models suit resistive loads like lighting, while C-curve units handle inrush currents from motors. Every unit belongs to the modular equipment category, fitting standard distribution boards.

Reliable Protection for 1, 2, and 3-Pole Applications

Circuit protection must match your system. The PLSM series offers single-pole breakers for standard circuits, double-pole units for isolated lines, and triple-pole versions for three-phase systems. Each breaker trips quickly during overloads or short circuits, protecting wiring and devices. The consistent design across pole counts means you can mix them in the same panel without confusion.

Easy Installation and Standard DIN Rail Mounting

Installers know that job time matters. PLSM breakers are engineered for fast mounting on standard DIN rails. Clear terminal covers and straightforward wiring make installation simple, even in tight panels. The compact modular footprint leaves room for surge protectors or contactors. Once snapped in, they lock securely, reducing rework and inspection delays.

Trusted Quality for Professional Installers

Eaton builds durable electrical components that last. The PLSM series meets strict safety standards and undergoes rigorous testing for consistent performance. The robust housing resists heat and impact, while internal contacts maintain low resistance over thousands of operations. Specifying PLSM breakers gives your clients peace of mind and ensures a product that installs right the first time.
