Product FAQs
5 answersWhat does the -1021 suffix indicate on the FH36015-1021?
The -1021 suffix designates a factory-installed 120/240VAC shunt trip. This internal accessory allows the breaker to be tripped remotely by applying voltage to the shunt trip coil, which is commonly used for emergency stop stations or control interlock circuits.
Which panelboards are compatible with the FH36015-1021?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features an I-Line plug-on connection that mounts directly to the bus stack and cannot be installed in standard NQ, NF, QO, or Homeline enclosures.
Are the trip settings adjustable on this F-frame breaker?
No, the FH36015-1021 features fixed thermal and fixed magnetic trip elements. The long-time and instantaneous (LI) protection functions are factory calibrated and do not support field adjustments.
Does the I-Line connection require bolted line-side wiring?
No, the I-Line mounting style utilizes plug-on jaws that push directly onto the panelboard bus stack. Only the load-side connections require manual wiring to the provided lugs, which accept 14 to 4 AWG copper or aluminum conductors.
Can I add a shunt trip to a standard FH36015 breaker in the field?
Internal accessories for legacy Square D F-frame breakers are typically factory-installed. Purchasing the FH36015-1021 ensures the 120/240VAC shunt trip is already integrated and calibrated from the factory.
