TB-1503 Fixed Barrier Terminal Block (15A / 600V) 3-Pin

Product Overview

The TB-1503 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 3 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 across all three lines.

This model is built to handle up to 15A at 600V, making it an ideal choice for standard single-phase AC power lines or dedicated multi-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 3 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.

Technical Specifications

Applications

The industry standard for clean, low-profile power routing, mains inputs, and multi-line terminal junctions:

• AC Mains Power Lines: Perfect for routing standard single-phase AC connections requiring Line (L), Neutral (N), and Ground (G) lines cleanly into equipment housings.

• Power Supplies & Inverters: Serving as the primary quick-access input/output terminal interface for industrial enclosed power supplies, transformers, and small inverters.

• 3-Wire Sensor Arrays & Actuators: Providing a clean, stable junction node for industrial field equipment requiring separate power ($V+$), ground ($GND$), and an analog/digital signal line ($OUT$).

• DIY Electronics & Prototyping: Ideal as a reliable power distribution hub for custom battery management systems (BMS), test benches, and heavy-duty hardware mockups.
