Dolphin Components tb-3-12 12-position Double Row Terminal Block

Product Description

The DOLPHIN COMPONENTS tb-3-12 is a 12-position double row terminal block designed for organized, secure wire termination in electrical panels, control systems, and distribution enclosures. This block accepts multiple conductors across two rows, allowing technicians to consolidate wiring connections within a compact footprint. It is a standard component in residential and light commercial electrical and control wiring work, installed by licensed electricians and HVAC controls technicians wherever neat, reliable conductor management is required.

The tb-3-12 is suited for use in electrical enclosures, control panels, and junction boxes where multiple circuits must be landed in a structured layout. Its double row configuration supports higher connection density without requiring additional rail space, making it practical for retrofit and new-installation work in tight enclosures. It ships as a single unit and carries a minimum order quantity of one.

Key Features

• 12-position layout provides high connection density in a single block
• Double row design reduces rail space requirements compared to single row blocks
• Suitable for control panel, junction box, and distribution enclosure applications
• Single-unit packaging with MOQ of one for flexible ordering

Compatibility

Designed as an OEM-style replacement or new-installation terminal block for use in standard electrical control panels and wiring enclosures requiring a 12-position double row configuration.

Installation Notes

Installation should be performed by a licensed electrician or qualified controls technician in accordance with applicable NEC requirements. De-energize and lock out the panel before installing or servicing terminal blocks. Ensure conductors are properly stripped, inserted fully, and secured according to the terminal block manufacturer torque guidelines marked on the housing.
