Powertite™ Series Plugs, Connectors and Receptacles use our versatile pin and sleeve design to provide safe, reliable power for any type of heavy duty equipment, fixed or portable. Available in 30, 60, 100, 150, 200 and 400 Amp designs, they feature widely spaced contacts recessed within an internal arc snuffing chamber, insulating blocks, positive polarization and a durable neoprene sealing bushing. Shell only or shell plus extra pole grounding provides safe, "make first, break last" grounding.
FeaturesAvailable in 30, 60, 100, 150, 200, and 400 Amp units.
Circuit breaking: in 30, 60, 100, and 200 Amp units, any arcing created as line and load terminals disengage is safely confined deep within terminal cavities. Plugs may be withdrawn in an emergency under full rated loads without separate disconnect switches (400 Amp plug is for disconnecting use only; not for current rupturing).
Positive polarization: only plugs and receptacles of same style, number of poles and ampere rating can be used together.
Suitable for use from -40 °C to 107 °C (-40 °F to 225 °F).
Available in two grounding styles: Style 1 (shell only) and Style 2 (shell and extra pole).
Locking screw and slot prevents plug cable collar from "backing off".
Controlled length contacts ensure that ground makes first and breaks last for added safety.
Contacts exert constant pressure along entire contact surface and provide electrical continuity.
Insulating blocks provide greatest dielectric and mechanical strength and lowest arc tracking.
Neoprene bushing compressed by cable collar prevents entrance of water. Bushing is highly resistant to hydrocarbon deterioration and is self-extinguishing.
30, 60, 100, and 150 Amp Powertite™ plugs also suitable for classified locations when used with Appleton EBR, EBRH, JBR, MD2SR, or DBR explosionproof interlocking receptacles.
