Description

The GE EP101ULD3 is a 1-pole miniature circuit breaker (MCB) in the ElfaPlus EP100 series, rated for 3A at 480Y/277V AC with a D-curve trip characteristic and 10 kAIC interrupt rating. It is approved under UL489 and IEC 60947-2, making it suitable for branch circuit device protection in both North American and international panel applications. Refer to manufacturer documentation to confirm compatibility with your specific application.

This breaker provides thermal-magnetic overcurrent and short-circuit protection on a single pole with a fixed thermal/fixed magnetic trip unit and D-curve instantaneous characteristics — designed for loads with high inrush currents such as motors, transformers, and solenoids. It mounts onto a standard 35 mm DIN rail with a bi-stable extraction system for secure installation and removal, and has a module width of 18 mm per pole. The terminal accepts 14 to 2 AWG copper or aluminum conductors via screw terminals, and reverse line feeding is permitted.

Each ElfaPlus MCB is rated for 10,000 operation cycles with a 6,000V impulse voltage withstand. The breaker includes a contact position indicator (red/green) and provides an option to lock the toggle in the OFF position. Certifications include UL489, cULus, CSA, IEC 60947-2, CE, EAC, CCC, and VDE.

About ACME MRO Solutions

We started ACME MRO Solutions to fix something we kept running into as contractors — plants down, parts slow, surplus listings you couldn't trust. Our goal is simple: get YOU the right component fast, with an honest description, so you can get back to running.

We describe what we see. Used items show signs of use; if a part has visible wear, damage, or a missing component, the condition description will say so. We don't claim anything is tested unless we tested it — and we don't bench-test parts where testing isn't practical or revealing (feed-through modules, breakers, mechanical components). When we do test something, we'll say so explicitly.

If something is our fault, we don't work through it — we make it right. We are proud to serve American manufacturing. Your uptime is our bottom line.
