Circuit Protection

We carry Sprecher + Schuh and Lovato Electric — comprehensive range of miniature circuit breakers, supplemental protectors, and fuse holders for motor control and panel building.

Circuit Protection — Reliable Short Circuit & Overload Protection for Industrial Control

When it comes to circuit protection, AMPS stocks what you need and knows how to apply it. We carry two industry-trusted brands — Sprecher + Schuh and Lovato Electric — offering a comprehensive range of miniature circuit breakers, supplemental protectors, and fuse holders for motor control, panel building, and industrial applications.

Circuit protection devices are the last line of defense for motors, machinery, and control circuits — protecting against short circuits, overloads, and fault currents that can damage equipment and create hazardous conditions. AMPS can help you select and size the right circuit protection for your application.

KEY FEATURES
