Eaton CHB260 Miniature Circuit Breaker

The Eaton CHB260 is a two-pole miniature circuit breaker (MCB) designed to protect electrical circuits from overloads and short circuits. It carries a 60 A rating and is specified for 120/240 V operation at 50/60 Hz, making it suitable for multi‑wire branch circuits encountered in many panel installations. As a 2P device, it interrupts both live conductors in a 120/240 V supply, ensuring simultaneous disconnection on fault conditions across the two poles. This CHB260 model is part of Eaton's NSB CHB260 family, offering a compact form factor that fits standard panelboards where two-pole protection is required. Use cases typically include protecting feeders and branch circuits in residential, commercial, or light industrial panels where 60 A capacity and dual-pole protection are appropriate. The 60 A rating supports circuits carrying substantial current while staying within common distribution panel limits, such as feeders to subpanels and high-load branch circuits.
