Product FAQs
6 answersWhat does the 1027 suffix mean on the FAL341001027 catalog number?
The 1027 suffix indicates that this breaker is equipped with a factory-installed 24VDC shunt trip accessory.
How does the 24VDC shunt trip function on this breaker?
The shunt trip allows the breaker to be tripped remotely. When a 24VDC control signal is applied to the shunt trip leads, it energizes a coil that mechanically opens the breaker contacts, providing an added level of safety for emergency shutdowns or automated control.
What type of mounting does the FAL341001027 require?
This is a unit-mount, feed-thru circuit breaker. It bolts directly to the mounting pan or enclosure backplate and uses wire lugs on both the line and load sides, rather than plugging into a busbar.
Are the trip settings on the FAL341001027 adjustable?
No, it features a fixed thermal-magnetic trip unit. Both the long-time (overload) and instantaneous (short circuit) trip functions are factory set and cannot be adjusted in the field.
What equipment is this F-frame breaker designed to fit?
It is designed for use in legacy Square D enclosures, switchboards, and motor control centers that accommodate unit-mount F-frame breakers.
Is the FAL341001027 a current production breaker?
The FAL series is a legacy F-frame molded case circuit breaker. While it is widely used in existing Square D switchboards and motor control centers, newer installations typically use PowerPact series breakers.
