Eaton Cutler-Hammer 20A Miniature Circuit Breaker CHBAB1020 Black 1P

Description

Product Overview

The Eaton Cutler-Hammer CHBAB1020 is a 20‑amp miniature circuit breaker designed for use in residential and light‑commercial distribution panels. Constructed from high‑quality thermoplastic housing with a sleek black finish, this breaker combines durability with a low‑profile footprint, allowing it to fit into standard 1‑pole 120 V slots without sacrificing performance. The breaker features a QCKLAG (quick‑clear) mechanism that trips rapidly under overload conditions, protecting wiring and connected devices from damage. With a rated breaking capacity of 10 kA, it meets stringent UL standards for safety and reliability. The CHBAB1020 model number is clearly stamped on the front, making identification and replacement straightforward during maintenance or upgrades.

Usage

This breaker is ideal for protecting lighting circuits, small appliance outlets, and dedicated loads such as HVAC units or electric water heaters. Its 20‑amp rating aligns with typical branch‑circuit requirements in modern homes, while the compact design makes it suitable for panels where space is at a premium. Installers can easily snap the breaker onto the bus bar, and the bolt‑on mechanism ensures a secure connection that resists loosening from vibration. Whether you are wiring a new construction, retrofitting an older home, or expanding a commercial panel, the CHBAB1020 provides the confidence of reliable over‑current protection. It is also compatible with most standard load‑center brands, simplifying inventory management for electricians and contractors.
