TB-1502 Fixed Barrier Terminal Block (15A / 600V) 2-Pin
Product Overview
The TB-1502 Fixed Barrier Terminal Block is a heavy-duty, dual-row electrical connector designed to provide a secure, high-voltage junction for power distribution, circuit isolation, and industrial field wiring. Featuring 2 fully isolated screw positions, this fixed-mount terminal strip employs rigid plastic barrier walls to physically separate connections, preventing electrical shorts, arc-overs, and accidental cross-contact from stray wire strands.
This model is built to handle up to 15A at 600V, making it an ideal choice for compact single-phase power runs or dedicated dual-line signal circuits. It comes complete with a clear, snap-on plastic safety cover that shields the live terminals from environmental dust, moisture, and accidental contact while allowing for instant visual inspection of the underlying connections.
Key Features
-
Heavy-Duty Power Rating: Engineered to safely manage demanding electrical demands up to 15A and 600V, making it highly reliable for both low-voltage DC arrays and high-voltage AC circuits.
-
High-Dielectric Barrier Insulation: Molded plastic partition walls isolate the 2 terminal screws, maximizing creepage distance between poles to maintain circuit integrity in high-vibration environments.
-
Clear Protective Safety Cover: A transparent, flame-retardant top shield clips firmly onto the housing, providing essential touch-safe protection without obscuring terminal wiring or marking strips.
-
High-Torque Screw Terminals: Rugged binder screws paired with integrated flat-bottom pressure plates ensure a high-pressure grip on connections without severing fine copper wire strands.
-
Flanged Surface Mount Base: Designed with pre-drilled mounting holes on the outer flanges of the robust housing, allowing for rapid, secure screw-down placement onto chassis plates, panels, or project enclosures.

Applications
The industry standard for clean, low-profile power routing, dedicated component inputs, and compact terminal junctions:
-
DC Power Input Rails: Serving as the primary quick-access power terminal interface for industrial electronic chassis, step-down modules, and custom control panels.
-
Single-Phase AC Main Lines: Perfect for routing compact 2-wire AC connections requiring Line (L) and Neutral (N) feeds securely into equipment housings.
-
Solitary Relay & Actuator Links: Providing a clean, high-voltage junction node for industrial field sensors, external limit switches, and solitary relay coils.
-
DIY Electronics & Prototyping: Ideal as a high-current distribution hub for custom battery management systems (BMS), test benches, and heavy-duty hardware mockups.
