Eaton BAB3100HS1 Thermal Magnetic Circuit Breaker 100A

Product Description

The EATON BAB3100HS1 is a thermal magnetic circuit breaker designed for overcurrent protection in commercial and residential electrical distribution systems. Thermal magnetic technology provides dual-mode protection: a bimetal strip responds to sustained overloads while an electromagnetic trip reacts to high-level short-circuit faults. The unit is a 3-pole configuration rated at 100 amps, making it suited for three-phase branch or feeder circuits where reliable fault interruption is required. Licensed electricians and electrical contractors are the primary installers of this breaker in panelboard and loadcenter applications.

This breaker is applied in commercial, industrial, and residential settings where a compact bolt-on or plug-in style circuit breaker is specified for 3-pole overcurrent protection. It fits panelboards and loadcenters designed to accept the BAB breaker series. Typical applications include motor branch circuits, feeder protection, and multi-wire branch circuits requiring coordinated overcurrent protection across all three phases simultaneously.

Key Features

• Thermal magnetic trip mechanism provides overload and short-circuit protection
• 3-pole design trips all phases simultaneously on a fault
• 100 amp continuous current rating for heavy branch and feeder loads
• Compact form factor fits BAB-series compatible panelboards and loadcenters
• Packaged 8 units per carton for contractor and supply-house stocking

Compatibility

Designed as an OEM-style replacement or new-installation thermal magnetic circuit breaker for panelboards and loadcenters that accept the EATON BAB breaker series footprint.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panelboard before removing or installing any circuit breaker. Verify that the bus bar and panel are rated to accept this breaker series and that the circuit conductor ampacity is properly coordinated with the 100 amp rating. Do not exceed the breaker's marked voltage and interrupting ratings for the installation.
