FAQs
To install the BAB3055HS, align it with the panel’s mounting holes and bolt it on in a three-pole configuration. Connect the three phase terminals and, if used, wire the 120–240 V shunt trip. Verify the 240/415 V rating and torque per Eaton’s datasheet, then perform insulation checks before energizing. The bolt-on design speeds retrofit projects.
Not interchangeably. The BAB3055HS uses a non-interchangeable trip unit, so it protects a circuit exactly as specified and maintains UL Listed and CSA Certified status. If you need a different amperage or voltage, choose a compatible BAB series model with matching trip characteristics to preserve protection coordination and compliance. Consult Eaton’s technical sheet for approved substitutions to ensure safety and warranty coverage.
The device provides a 55 A amperage rating, a 10 kAIC interrupt rating, and a 240/415 V operating range in a three-pole, bolt-on package. It is HACR rated and CSA Certified UL Listed, with a 120-240 V shunt trip option available. This combination supports reliable protection for high-demand industrial loads while maintaining regulatory compliance.
It’s well-suited for motor control centers, service panels, and distribution boards in manufacturing, packaging, and process industries. The three-pole 240/415 V rating supports multi-phase protection for feeders, MCCs, and control panels, while bolt-on mounting simplifies retrofit into existing gear. Its HACR rating helps meet energy safety requirements across commercial and industrial facilities.
Warranty is one year, reflecting Eaton's confidence in reliability. The robust 10 kAIC interrupt rating reduces nuisance trips and unplanned downtime, contributing to ROI through fewer process interruptions. The bolt-on mounting and standard terminals simplify maintenance, stock planning, and spares management, while CSA UL compliance supports regulatory assurance across regions.
