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 fuseholders or mini-circuit breakers and the 60A models are available with supplementary protectors. (60A models are not available with fuses due to space constraints).
Fuseholder Equipped Models
MELTRIC’s DSN Decontactor™ Series switch rated plugs and receptacles are UL rated to withstand and close-into a short circuit current up to 100kA in circuits protected by RK1 current limiting fuses or other fuses with lower let through energy like the Class CC type the fuseholders are designed for. 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 are available with 20A or 30A receptacles and 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.
