QYU ONE-POLE 277 VAC SUPPLEMENTARY PROTECTORS
Description
QYU 277 Vac supplementary protectors are available for surface, flush or DIN-rail mounting in 1-pole
construction. Supplementary protectors are 3/4 in. (19.05 mm) wide.
Table 9:
Applications
One-pole QYU 277 Vac supplementary protectors are UL Recognized Component (meets UL 1077) to
be applied on systems where the maximum phase-to-ground voltage is 277 Vac or less, including use
of 240 Vac corner grounded delta “grounded B” systems.
These devices are designed to provide supplemental overcurrent protection in accordance with Article
240-10 of the 2005 NEC, which states that thermal-magnetic supplementary protectors cannot be
used to replace the primary branch-circuit protection in an application. When used in combination with
branch-circuit protection, as required in Article 210 of the 2005 NEC, these supplementary protectors
can be used to protect lighting fixtures, appliances and other equipment or internal circuits and
components of equipment.
Tripping Characteristics
The QYU trip characterstics are identical to those of the same amperage QOU circuit breaker. See trip
curves 730-1, -3, -4 and -5.
