OVRHTE surge protective devices 

| Product manual  7

Applying power

–  Apply power to unit by closing the circuit breaker. 
–  Check OVRHTE lights. Protection is active when all lights are 

illuminated.

Troubleshooting

Unit should be replaced if:

–  Circuit breaker trips and cannot be reset
–  One or more lights on OVRHTE are not illuminated

Options

The OVRHTE is available with these options:

–  Dry relay contacts for remote monitoring. Upon failure of any 

phase, the relay’s N.O. and N.C. contacts will change state. 
The contacts are rated at 110VDC/125VAC with maximum 
switching power of 30W DC/62.5VA AC.

–  457.0 mm (18 in.) of 19.1 mm (.75 in.) nonmetallic flexible 

conduit and a fitting that connects to the provided 19.1 mm 
(.75 in.) hub.

–  19.1 mm (.75 in.) x 76.2 mm (3 in.) nipple that connects to the 

provided 19.1 mm (.75 in.) hub.

Standards/Compliance

–  Listed by UL to UL 1449 4th Edition for Type 2 SPD 

application, cUL, and UL1283

–  Compliant to IEEE C62.41.1-2002, C62.41.2-2002, and 

C62.45-2002

–  NFPA 70 [NEC], Article 285
–  RoHS compliant

Operation/Maintenance

The only operational verification necessary on the OVRHTE is to 
observe that the lights are illuminated. There is no maintenance 
to be performed on the OVRHTE nor does the OVRHTE contain 
any user-serviceable parts.
