Russellstoll 3328-78 Pin Sleeve Plug 60A 3P4W 480VAC

Product Description

The RUSSELLSTOLL 3328-78 is a heavy-duty pin and sleeve power connector plug rated for 480 VAC and 60 amperes across a 3-pole, 4-wire configuration. Designed for industrial and commercial electrical distribution applications, this plug provides a secure, reliable connection in demanding environments where high-current power transfer is required. Licensed electricians install this type of connector on power distribution systems, portable equipment hookups, and temporary or permanent panel feeds where robust plug-and-socket connectivity is essential. The 3-pole, 4-wire design accommodates three current-carrying conductors plus a ground or neutral, making it suitable for 3-phase or split-phase high-current loads.

The 3328-78 is suited for industrial facilities, construction sites, commercial buildings, and any application requiring a dependable 480 VAC, 60-amp locking connector. It is appropriate for use with compatible pin and sleeve receptacles and inlets in industrial power distribution panels, portable power equipment, and machinery hookups. The rugged construction is intended for environments subject to frequent connect-disconnect cycles, mechanical stress, or exposure to industrial conditions.
