Explosionproof junction box (18 x 18 x 8) UL and CSA listed for Class I, Division 1, Groups B-C-D areas. Mounted on the bottom are two GDT-B1728-42SL-L36 explosion proof receptacles. Supplied with covers and female inserts for line side power, each of these receptacles is pre-wired and factory sealed. The #4/0 line wires from these receptacles are landed on three power terminal blocks. One side of these blocks will accept two each #4/0 wires (one from each receptacle) and the other side will accept one each 500 MCM conductor. The grounds will be attached to a stud mounted on the inside of the enclosure. The #10 relay contacts will be landed on terminal blocks. These wires go to a contactor or a circuit breaker with shunt trip or under voltage release.

Explosion proof stainless steel NEMA 4X enclosure with pre-mounted components customized to your specification. The completed receptacle enclosure is designed for Class I, Division 2, Group B-C-D hazardous areas. It is also EEx d (ATEX) certified, see EMR's. Other options include control buttons (including: push, selector switch, mushroom push, stop, and key switch), pilot lights, zener barriers and various receptacle options.
