Eaton OCPD Overcurrent Protection Device for Fire Pumps
This controller is quoted to your specifications. Call or Request a Quote Today.
The Eaton OCPD is an overcurrent protection device for electric fire pumps. It provides an upstream means of disconnecting incoming power from an electric fire pump controller, so the controller can be fully isolated for maintenance and site personnel safety. The OCPD is service entrance rated and UL listed for fire pump service. Every OCPD is built to order, so we quote each one to your horsepower, voltage and enclosure. Call (786) 336-5783 or send us your catalog number or spec section.
What the OCPD does
Installed upstream of the fire pump controller, the OCPD lets the controller be completely de-energized at the source. That reduces arc flash exposure when the controller is serviced, because no part of it needs to stay live. Per Eaton, the OCPD is acceptable for installation in the USA and is UL listed for fire pump service under the requirements of NFPA 20 section 9.2.3.4.1 and NEC (NFPA 70) section 695.4(B)(2)(a)(2), along with the requirements for the alternate (Source 2) circuit in NEC section 695.3(F)(2). Confirm requirements for your project with the engineer of record and the authority having jurisdiction.
The OCPD is used with electric fire pump controllers, including the EPCT Fire FD and FT series.
OCPD features
- Service entrance rated: suitable for use as service entrance equipment in the USA
- Flange-mounted disconnect: Eaton flange-mounted disconnect, lockable in both the open (OFF) and closed (ON) positions
- Lockable latches: lockable quarter-turn handles on Size 2–3 and Size 5 enclosures; key lock handle on the Size 6 enclosure (see the dimensional drawings in the bid submittal)
- Enclosure: UL Type 2 (drip-proof) standard
OCPD catalog numbers explained
OCPD catalog numbers follow the same horsepower, voltage and language pattern as Eaton's electric fire pump controllers. For example, OCPD-100-D-L1 is sized for a 100 HP fire pump motor at 480V, three phase, 60Hz, with English labels in the standard NEMA 2 enclosure.
| Segment | Example | Meaning |
|---|---|---|
| Model | OCPD | Overcurrent protection device for fire pumps |
| Horsepower | 100 | Fire pump motor horsepower the OCPD is sized for |
| Voltage | D | Supply voltage code, for example A = 208V/60Hz · B = 240V/60Hz · D = 480V/60Hz |
| Language | L1 | Label language (L1 = English) |
