The Allen-Bradley Bulletin 100 NEMA Contactors are heavy-duty motor control devices designed to meet NEMA standards for industrial applications. Known for their durability and reliability, these contactors are built to handle higher horsepower loads and are commonly used in harsh environments, including oil & gas, water treatment, and manufacturing facilities. Bulletin 100 NEMA Contactors provide straightforward installation and long-lasting performance in both starter and switching applications.

These contactors are used for starting and stopping motors, switching resistive or inductive loads, and isolating power in industrial systems. Because they meet NEMA standards, they’re often selected for high-load or high-reliability applications in sectors like utilities, industrial manufacturing, and infrastructure.
NEMA contactors are typically larger, more conservatively rated, and built to last under continuous duty with higher margins. IEC contactors are more compact and modular, optimized for specific application ratings. NEMA designs are favored in North America for systems requiring high endurance and broad application flexibility.
Coil voltages commonly include 24V DC, 120V AC, 240V AC, and 480V AC. The coil code is typically indicated in the suffix of the part number. It’s important to confirm voltage compatibility when ordering replacement or spare units.
Yes, Bulletin 100 NEMA contactors support a variety of auxiliary contact blocks, timing relays, and mechanical interlocks. These accessories allow for customization in multi-motor systems, interlocked starter panels, or advanced control schemes.
Yes. They are commonly paired with thermal overload relays such as the Bulletin 592 series to form full motor starters. This combination offers reliable protection against motor overcurrent and excessive heat buildup.
