Schneider Electric HDL36100SA 3 Pole Circuit Breaker
The Schneider Electric HDL36100SA is a 3 Pole thermal magnetic molded case circuit breaker with a current rating of 100 Amps and a voltage rating of 600VAC. It has an interrupting rating of 18kAIC at 480VAC. The HDL36100SA has a feed-thru connection type and includes long time and instantaneous trip functions.
What does the "SA" suffix mean in the HDL36100SA catalog number?
The "SA" suffix indicates that this breaker comes with a factory-installed 110-130 VAC shunt trip. This accessory allows the breaker to be tripped remotely using a control voltage signal.
What does the "D" in the HDL36100SA part number signify?
The "D" designates the interrupting rating tier within the Square D PowerPacT H-frame family. For this specific breaker, the D-rating provides an 18 kA interrupting capacity at 480 VAC.
Is the HDL36100SA compatible with Square D I-Line panelboards?
No, the HDL36100SA is a unit-mount (feed-thru) circuit breaker designed to be hardwired in industrial control panels, switchboards, or standalone enclosures. It does not have the plug-on jaw connections required for I-Line panelboards.
Can the HDL36100SA be reverse fed?
Yes, standard thermal-magnetic PowerPacT H-frame breakers like the HDL36100SA are suitable for reverse feeding. This allows you to connect the incoming line power to either the top or bottom lugs without affecting the breaker's protective functions.
Can I field-install a shunt trip on a standard HDL36100 instead of buying the HDL36100SA?
Yes, PowerPacT H-frame breakers support field-installable accessories. However, purchasing the HDL36100SA provides the 110-130 VAC shunt trip already factory-installed, which saves assembly time and ensures proper factory testing.
What type of trip unit is equipped on the HDL36100SA?
This breaker features a fixed thermal-magnetic trip unit with Long-Time (L) and Instantaneous (I) protection. Both the thermal overload and magnetic short-circuit trip thresholds are factory-fixed and cannot be adjusted.
Does the HDL36100SA include a Visi-Trip indicator?
Yes, Square D PowerPacT H-frame breakers feature a Visi-Trip indicator. When the breaker trips, the handle snaps to a center position and a highly visible red indicator appears, making it easy to identify a tripped breaker in a crowded panel.
