Eaton CHH2100H4X Thermal Magnetic Circuit Breaker - UL 489

Two-pole bolt-on mounting simplifies panel installation and reduces wiring errors. This solid mechanical fit translates to faster tune-ups and fewer reworks on crowded Eaton CH series panelboards. In practical terms, technicians can swap breakers with minimal panel disruption when upgrading to larger continuous loads in industrial automation environments. The 100 A amperage rating protects feeders and main lugs while keeping nuisance trips within predictable thresholds. The bolt-on design also supports quick field replacement, reducing downtime during maintenance windows. This is valuable for manufacturing lines that demand steady, uninterrupted power to PLCs and drives. The 120/240 V voltage rating supports common industrial loads, enabling flexible distribution across machine panels and control cabinets without the need for additional transformers. This compatibility simplifies procurement and reduces spare-part inventories for mixed-load facilities. With a 42 kAIC interrupt rating, the breaker limits arc energy and enhances personnel safety during short-circuit events. This performance is vital for high-energy electrical environments where reliability and fault containment directly impact uptime and maintenance costs. UL 489 certification provides recognized safety compliance for low-voltage power distribution components, reinforcing regulatory alignment and reducing approval timelines for panel installations. The CHH2100H4X is built to endure industrial duty, with a robust bolt-on form factor that supports rapid replacements during planned outages or system upgrades. Compatibility with 37MM and 37SS three-phase modular metering stacks simplifies integration in modern power-distribution schemes, enabling scalable protection as facilities grow and processes evolve.
