PRODUCT DESCRIPTION
OFAF3H500 Five-Hundred-Ampere Fuse Link
ABB OFAF3H500 is a 500 A DIN-type fuse link in the FuseLine OFAF universal gG range. The ABB catalogue places it in IEC size 3 and rates the AC range up to 500 V. Its gG characteristic provides the general-purpose fuse behavior specified for that range rather than the aM motor-fuse characteristic.
The exact OFAF3H500 row lists 44.0 W power loss and a delivery batch of one fuse link. The dimensional and DC-rating table also lists size 3, 250 to 500 A fuses at 440 V DC for a 15 to 20 ms time constant. Fuse-base fit, voltage type and the circuit coordination remain distinct selection requirements.

SYSTEM INTEGRATION
Integrate OFAF3H500 within ABB FuseLine OFAF
Select an IEC size 3 fuse base suitable for the OFAF3H500 knife-contact arrangement and the intended circuit. The 500 A current selection must be coordinated with the installation rather than chosen only from the available holder format.
Use the 500 V AC gG rating for the AC circuit selection. Where a DC circuit is involved, apply the separate 440 V DC table only within the listed 250 to 500 A size 3 range and its 15 to 20 ms time-constant condition.
Include the 44.0 W catalogue loss in the enclosure heat review and use the applicable fuse-base mounting instructions. The gG and aM ranges have different purposes; a mechanically similar fuse must not silently change the circuit characteristic.
Features:
- Rated current: 500 A
- AC voltage rating: 500 V AC
- ABB FuseLine OFAF
Use OFAF3H500 only within the documented ABB FuseLine OFAF arrangement and applicable installation instructions.
INTERCHANGEABILITY
Replace OFAF3H500 within ABB FuseLine OFAF
Verify OFAF3H500, 500 A, gG and IEC size 3 against the removed fuse and the circuit schedule. Identify whether the circuit is AC or DC before comparing the voltage rating.
Isolate the circuit and confirm it is safe before handling the fuse link under the site electrical procedure. Inspect the fuse-base contacts and holder condition, and use the appropriate handling equipment for the installed base.
After replacement, confirm secure seating, the unchanged current and characteristic selection, and the circuit condition that caused the original fuse operation. Do not raise the current rating to prevent repeated operation without a coordination review.
Features:
- OFAF3H500 complete suffix
- Applicable DC current group: 250 to 500 A, IEC size 3
- 500 A, gG and IEC format 3 matched
Use OFAF3H500 only within the documented ABB FuseLine OFAF arrangement and applicable installation instructions.

Is OFAF3H500 a 500 A or 500 V designation?
The exact OFAF3H500 catalogue row is 500 A; its OFAF gG range is separately rated up to 500 V AC. -
Which IEC fuse format fits OFAF3H500?
ABB lists OFAF3H500 in IEC size 3, so the fuse base and knife-contact arrangement must match that format. -
What power loss is listed for OFAF3H500?
The exact manufacturer row for OFAF3H500 gives 44.0 W power loss. -
Is OFAF3H500 an aM motor fuse?
No. OFAF3H500 is listed in the universal gG range. Do not replace it with an aM characteristic based only on current and physical fit. -
Can the AC voltage label of OFAF3H500 be used as its DC rating?
No. For OFAF3H500, the separate size 3 DC table gives 440 V DC at 250 to 500 A with a 15 to 20 ms time constant. -
What must be inspected before fitting a new OFAF3H500?
Inspect the fuse-base contacts, holder condition and circuit fault cause before installing OFAF3H500, after the circuit is safely isolated. -
What is the catalogue delivery batch for OFAF3H500?
ABB lists a delivery batch of one fuse link for OFAF3H500; confirm the ordered quantity separately on the distributor quotation. -
Which ratings should a distributor preserve in a OFAF3H500 quote?
State OFAF3H500, 500 A, IEC size 3 and gG, with the intended AC or DC circuit requirement. Identify any fuse base or handling accessory separately.
