Molded Case Circuit Breaker, 3-Pole, 100 A, 480Y/277 V AC, Bolt-On, Type EDB

Product Description

This molded case circuit breaker is a Type EDB, 3-pole device rated 100 A for 480Y/277 V AC systems, designed for bolt-on installation in Square D NF panelboards. It employs a fixed thermal-magnetic trip unit providing long-time and instantaneous protection for branch circuits across lighting, HVAC, and general distribution applications. The breaker features LI functions, VISI-TRIP indication of trip status, and short-circuit/overload protection with interrupting ratings up to 18 kA at 480 V per published data. Aluminum lugs accept a broad conductor range to simplify termination in panelboard assemblies, and the E-frame construction maintains a compact footprint at 5.66 x 2.94 x 4.05 inches. Suitable for HID and HACR applications, it includes local trip indication and is listed to UL 489 and certified to CSA standards. Use where reliable, bolt-on panelboard protection and consistent coordination within the EDB family are required.
