Product FAQs
6 answersWhat does the 1212 suffix indicate on the LAL363501212 catalog number?
The 1212 suffix designates a factory-installed auxiliary switch with a 1A/1B contact configuration (one normally open and one normally closed contact). This allows for remote monitoring of the breaker status.
How do I wire the auxiliary switch contacts on this 1212 suffix breaker?
The factory-installed auxiliary switch uses specific wire colors for connection: the yellow wire is normally open, the blue wire is normally closed, and the striped wire is the common connection.
Can I use parallel conductors with the lugs on the LAL363501212?
Yes, the included lugs support parallel runs. You can terminate either a single 1 AWG to 600 kcmil conductor or two 1 AWG to 250 kcmil conductors per phase, using either aluminum or copper wire.
Can I adjust the trip settings on the LAL363501212?
The instantaneous (magnetic) short-circuit trip threshold is adjustable, allowing you to tune the breaker response to inrush currents. However, the long-time (thermal) overload protection is fixed at 350 amps.
Is the LAL363501212 an I-Line or unit-mount breaker?
This is a unit-mount, feed-thru breaker. It is designed to be hardwired via lugs in switchboards, panelboards, or individual enclosures, rather than plugging into an I-Line busway.
Is the LAL363501212 suitable for HVAC applications?
Yes, this breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment that requires group motor protection.
