QOU260 Square D 60 A 2-pole 120/240V Circuit Breaker

Description

Product Overview

The QOU260 Square D circuit breaker is engineered to deliver dependable over‑current protection for a wide range of electrical applications. Rated at 60 amps and designed for a 2‑pole configuration, this miniature circuit breaker (MCB) operates seamlessly in both 120 V and 240 V environments, making it a versatile choice for residential, commercial, and light‑industrial panels. Constructed with a high‑quality thermally‑magnetic trip unit, the breaker responds quickly to overloads while providing a reliable magnetic trip for short‑circuit conditions. Its DIN‑rail mounting style ensures a compact footprint, and the lug‑type electrical connections allow for straightforward, secure wiring to busbars or terminal strips. The QOU260 meets rigorous industry standards for safety and performance, offering a durable solution that resists wear, corrosion, and mechanical stress over years of service.

Usage

This breaker is ideally suited for installation in distribution boards that serve lighting circuits, small appliance loads, and dedicated motor feeds. Whether you are outfitting a new home, upgrading an existing panel, or configuring a commercial office sub‑panel, the QOU260 provides the necessary protection for circuits that draw up to 60 amps. Its 2‑pole design makes it perfect for handling split‑phase loads, such as electric ranges, HVAC units, and water heaters that require both hot legs of a 240 V supply. The DIN‑rail mounting system simplifies panel layout, allowing electricians to slide the breaker into place without the need for additional hardware. The lug connections accept a range of wire gauges, facilitating flexible installation in tight spaces while maintaining a solid, low‑resistance connection.

FAQ

What voltage ratings does the QOU260 support?

The breaker is rated for a maximum voltage of 230 VAC, making it suitable for both 120 V and 240 V split‑phase applications commonly found in North American and international installations.

Can the QOU260 be used in outdoor panels?

While the breaker itself is designed for indoor use, it can be installed in outdoor-rated panels that provide adequate protection from the elements. Ensure the enclosure meets the required NEMA rating for outdoor exposure.

What wire gauge is compatible with the lug connections?

The lug terminals accept copper conductors ranging from 10 AWG to 14 AWG, allowing you to match the breaker to the appropriate circuit size and load requirements.

Is the QOU260 compatible with existing Square D panels?

Yes, the breaker conforms to Square D’s DIN‑rail specifications, so it integrates seamlessly with existing Square D distribution boards and load centers without the need for additional adapters.

How does the thermal‑magnetic trip mechanism work?

The thermal element reacts to prolonged overloads by bending a bimetallic strip, which gradually trips the breaker. In the event of a short circuit, the magnetic coil generates an instantaneous magnetic force that trips the breaker within milliseconds, providing rapid protection against dangerous fault currents.
