The SQDQOB3601021 is a reliable Square D 3-pole 60A breaker designed for 250V applications, featuring a 120V shunt trip for enhanced safety and remote operation. Ideal for residential or commercial use, this breaker ensures efficient circuit protection and compliance with electrical standards, making it an essential component for your electrical system.
The 120V shunt trip is an accessory coil that allows the breaker to be tripped remotely — for example, by a fire alarm system, emergency stop button, or building automation control. When 120V AC is applied to the shunt trip terminals, it mechanically trips the breaker open. Wiring must be done by a qualified electrician in accordance with CEC requirements; a dedicated 120V control source must be available at the panel.
Yes. The QOB bolt-on series is used in both residential and light commercial Square D QO panelboards that accept bolt-on breakers. For larger commercial or industrial switchboards, a molded-case breaker may be more appropriate — contact us and we can help you determine the right fit for your application.
