Product FAQs
7 answersWhat does the -1212 suffix indicate on the Square D FHL36030-1212?
The -1212 suffix denotes that the circuit breaker includes a factory-installed 1A/1B auxiliary switch. This allows for remote signaling of the breaker's open or closed status to a control system or indicator light.
What is the modern replacement for the legacy FHL36030-1212 circuit breaker?
The FHL36030-1212 is a legacy F-frame breaker that has been discontinued. The direct modern replacement is the Square D PowerPacT H-frame series, specifically the HGL36030, though mounting adaptations may be required depending on your existing enclosure.
What types of equipment are compatible with the FHL36030-1212?
This unit-mount F-frame breaker is designed for installation in legacy Square D enclosures, industrial switchboards, and motor control centers that accept feed-thru lug configurations.
How is the FHL36030-1212 mounted in an electrical enclosure?
This is a unit-mount, feed-thru circuit breaker. It does not plug onto a busbar or use an I-Line connection. Instead, it secures directly to the enclosure backpan and uses mechanical lugs on both the line and load sides for hardwired point-to-point connections.
How does the thermal-magnetic trip unit function on the FHL36030-1212?
The breaker features a fixed thermal-magnetic trip unit with long-time and instantaneous (LI) functions. The thermal component provides protection against sustained overloads, while the magnetic component delivers immediate tripping during short circuits. Both trip thresholds are factory-fixed and non-adjustable.
Is the FHL36030-1212 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 specialized overcurrent protection.
Can the FHL36030-1212 be installed in a modern PowerPacT panelboard?
No, the FHL36030-1212 is a legacy F-frame breaker with specific physical dimensions. It will not fit into modern panelboards designed exclusively for PowerPacT H, J, or L-frame breakers without specialized retrofit hardware.
