Description
2-Pin Barrier Terminal Block with Protective Cover
Product Overview
The 2-Pin Barrier Terminal Block is a heavy-duty, panel-mount electrical connector designed to provide a secure, high-current distribution point for power or signal lines. Featuring two fully isolated screw terminals, this terminal strip utilizes rigid plastic barrier walls to physically separate connections, preventing accidental electrical shorts, bridging, and wire strand cross-contact.
This model comes equipped with a transparent, clip-on plastic safety cover that shields live terminals from environmental dust, moisture, and accidental touch while allowing for quick visual inspection of the connections. Each position features a rugged steel pressure plate screw terminal capable of clamping raw stranded wire, solid wire, or crimped spade/ring terminals with exceptional mechanical retention.
Key Features
-
High-Dielectric Barrier Walls: Raised plastic walls isolate each terminal screw, maximizing the creepage distance between poles to eliminate short-circuiting risks even in high-vibration settings.
-
Transparent Protective Cover: Clear, flame-retardant top shield snaps firmly into place, providing excellent IP-rated touch protection against accidental finger contact and dust accumulation.
-
Rugged Screw-Clamp Terminals: Heavy-duty binder screws paired with internal pressure plates ensure high-torque wire retention without severing fine copper strands.
-
Flanged Surface Mount Holes: Features rigid integrated mounting holes on both outer flanges of the base housing, allowing for secure screw-down installation onto chassis plates, panels, or enclosures.
