Special features
Bolt-on mounting
Feature → Business Impact → Application: The BAB2100S is a two-pole, 100 A device with a 10 kAIC interrupt rating, delivering strong fault isolation to minimize damage and downtime in demanding enclosures. This translates to improved equipment life and lower replacement costs in motor drives and production lines. Application-wise, it fits 120/240 V control panels and machinery dashboards where space is limited, thanks to its compact 3.3 in width, 3.8 in depth, and 4.9 in height with 1 lb weight for easy handling during field installs. Feature → Business Impact → Application: Bolt-on mounting reduces installation time and improves reliability by ensuring repeatable torque and secure mounting, critical in vibration-prone environments and high-duty cycles such as packaging lines or conveyors. Application: Retrofit projects and spare-parts strategies. Feature → Business Impact → Application: HACR rated and certified capabilities provide compliance assurance for HVAC and motor-control applications, supporting NEC adherence and risk reduction in commercial facilities. Application: HVAC units, fans, pumps and general purpose motors. Feature → Business Impact → Application: Shunt-trip capability (where specified) enables remote isolation for enhanced safety and control in centralized protection schemes, reducing risk during maintenance and emergencies. Application: Integrated control systems and safety interlocks. Feature → Business Impact → Application: Non-Interchangeable trip design preserves consistent performance and reduces mis-matching of replacement components in legacy systems. Application: Fleet protection programs and asset standardization.

FAQs
Install the BAB2100S using its bolt-on mounting method in a suitable two-pole section of the control panel. It fits standard enclosure footprints with dimensions of 3.3 in width, 3.8 in depth, and 4.9 in height, weighing about 1 lb. Ensure the conductors are sized for 100 A and torque specs are followed to prevent overheating and secure bus connections.
The BAB2100S is rated for 120/240 V operation, with a 100 A amperage rating and a 10 kAIC interrupt rating. It is a two-pole, non-interchangeable device, suitable for standard industrial circuits. If remote isolation is required, shunt-trip capability may be used where specified by your panel design.
Yes. The BAB2100S is HACR rated and UL Listed with CSA Certification, making it appropriate for motor control and HVAC protection in commercial and industrial environments. This ensures NEC compliance and reliable performance under duty cycles common to motors, fans, and compressors, with reduced nuisance tripping in variable load conditions.
The device is UL Listed and CSA Certified, with HACR rating for motor and HVAC applications. These certifications support compliance in a wide range of international and domestic installations, providing traceability and safety assurance for panel assemblies, service upgrades, and fleet standardization.
By combining 100 A protection with a 10 kAIC interrupt rating, bolt-on installation, and durable construction, the BAB2100S reduces unplanned downtime and maintenance costs. The 1-year warranty adds initial risk protection, while standardization across a fleet lowers spare-part complexity and improves lifecycle costs in rugged industrial environments.
