Dolphin Components tb-3-10 Terminal Block 10P 2 Row

Product Description

The DOLPHIN COMPONENTS tb-3-10 is a double-row terminal block rated for 300 volts and 20 amps, designed for organized multi-circuit wiring connections in control panels and electrical enclosures. It features 10 poles arranged in 2 rows with binding head screw terminations, providing secure, serviceable connections without requiring specialized crimping tools. The glass-filled thermoplastic housing in black finish offers resistance to heat and mechanical stress, while zinc-plated steel terminals deliver reliable conductivity and corrosion resistance. Licensed electricians and controls technicians install this type of terminal block in low-voltage and line-voltage wiring applications across HVAC, industrial, and commercial electrical systems.

The tb-3-10 is suited for residential and light commercial control panel wiring, motor control centers, and electrical distribution enclosures where a compact, high-pole-count terminal block is required. Its 0.38-inch center spacing and 4.41-inch overall length make it appropriate for standard DIN rail and panel-mount configurations where space is a primary consideration. This terminal block is a practical choice for panel builders and service technicians consolidating multiple field wiring runs into a single organized termination point.

Key Features

• 10-pole, 2-row configuration consolidates multiple circuits in a compact footprint
• Rated 300 volts and 20 amps for use in a wide range of control and power wiring applications
• Binding head screw terminal type allows tool-accessible, re-torqueable connections
• 0.38-inch center spacing supports dense panel layouts
• Glass-filled thermoplastic housing resists heat, impact, and mechanical stress
• Zinc-plated steel terminals provide corrosion resistance and reliable conductivity

Compatibility

Designed as a general-purpose double-row terminal block for use in control panels, electrical enclosures, and wiring distribution applications requiring a 10-pole, 2-row binding head screw configuration rated at 300 volts and 20 amps.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements for terminal wiring and panel construction. De-energize and lock out the circuit before making or breaking any terminal connections. Use an appropriate flat-blade screwdriver for the binding head screws and confirm wire gauge is compatible with the 20-amp terminal rating before terminating conductors. Inspect housing and terminals for damage before installation and do not exceed the rated voltage or amperage.
