Product Overview

The QO2100VH is a Square D QO series plug‑in miniature circuit breaker rated 100 amps for 120/240V single‑phase service.

It features a 22 kA interrupting rating and is HACR rated (Heating, Air Conditioning, Refrigeration).

Key Features

• 100 Amp, 2‑pole plug‑in breaker for 120/240V systems
• 22 kA interrupting rating
• HACR rated for HVAC and refrigeration equipment
• Square D QO series form factor (plug‑in miniature)

Function and Purpose

This breaker provides overcurrent protection for branch circuits and loads requiring up to 100 amps on 120/240V single‑phase systems. As a 2‑pole device, it simultaneously interrupts both ungrounded conductors when a fault or overload occurs.

• Protects conductors and connected equipment from overcurrent conditions
• 2‑pole design ensures simultaneous disconnect of both hot legs

Electrical Ratings and Performance

Use this model where the system requires a 100 A trip rating and a 120/240V nominal voltage. The breaker has a 22 kA interrupting rating, indicating the maximum fault current it is rated to safely interrupt.

• Ampacity: 100 A
• Voltage: 120/240V
• Interrupting rating: 22 kA

Panel Compatibility and Form Factor

The QO2100VH is a plug‑in miniature breaker in the Square D QO series form factor. It is intended for installation in panels that accept Square D QO plug‑in breakers.

• Plug‑in QO series form factor
• Designed for use with compatible Square D QO panelboards (confirm panel model for mechanical fit)

Typical Applications

This breaker is HACR rated, making it suitable for protecting circuits that serve heating, air conditioning, and refrigeration equipment where HACR listing is required.

Beyond HVAC loads, it can be used where a 100 A, 2‑pole protective device with a 22 kA interrupt rating is appropriate.

• HVAC and refrigeration circuits (HACR rated)
• General 120/240V branch circuit protection up to 100 A
