162 Receptacles & Wall Boxes with Integral Circuit Protection MELTRIC’s receptacle/wall box combinations with integral circuit protection combine the safety of a MELTRIC DSN series switch-rated receptacle with the convenience of local circuit protection in a compact package. The receptacle is premounted to the box and wired to the circuit protection device for easy installation. Models are available with or without a viewing window and in either painted mild steel or stainless steel enclosures. The 20A and 30A models are available and equipped with fuse holders or mini-circuit breakers and the 60A models are available with fuseholders or supplementary protectors. Fuseholder Equipped Models MELTRIC’s DSN Series switch-rated plugs and receptacles are UL rated to withstand and close-into short circuit currents up to 100kA in circuits protected by RK1 current limiting fuses or other fuses with lower let through energy like Class CC and Class J fuses. This allows users to take advantage of the DSN’s capablities in applications where higher fault currents are not already protected with the required fusing. Fuseholder models feature Ferraz Shawmut Ultra-Safe Fuse Holders (UL 512 / IEC 269). The fuseholders have a blown fuse indicator light for each pole and pivot open for easy and finger safe fuse replacement. Fuses are not provided. They should be selected for the specific application. Circuit Breaker Equipped Models Circuit-breaker equipped models allow users to provide overload protection in a convenient location near the application. The 20A & 30A models feature Eaton WMZT miniature circuit breakers (UL 489) and the 60A models use Eaton WMZS supplementary protectors (UL 1077). All are provided standard with a ‘C’ trip curve. A ‘D’ trip curve for the 20A and 30A breakers, and a ‘B’ trip curve for the 60A supplementary protectors are also available as options. Trip Curve Characteristics “B” Curve: The protective device will instantaneously trip @ 3X to 5X its rated current “C” Curve: The protective device will instantaneously trip @ 5X to 10X its rated current “D” Curve: The protective device will instantaneously trip @ 10X to 20X its rated current
