Carrier 1423570 Terminal Block
The Carrier 1423570 Terminal Block is an OEM-grade power distribution block engineered for high-amperage HVACR applications. Built by Marathon Special Products (142 series), this 3-pole terminal block is a direct replacement for power termination in Carrier, Bryant, and Payne industrial units, including 30RAN series chillers. Rated for 175 Amps and 600 Volts, it features a robust phenolic insulator base designed to withstand high thermal loads in demanding mechanical environments. The line side accepts a single 2/0 to #14 AWG conductor, while the load side provides four openings for #4 to #14 AWG wiring, allowing for efficient multi-wire circuit branching. The tin-plated aluminum connectors and nickel-plated steel screws ensure superior conductivity and corrosion resistance when used with either copper or aluminum conductors (CU7AL rated). For technicians performing code-compliant repairs, this HVAC electrical connector meets UL 1059 and CSA 22.2 No. 158 standards, ensuring reliable power management and short circuit current ratings (SCCR) within the control cabinet.
Key Benefits- High Current Capacity: Rated for 175 Amps, making it suitable for heavy-duty chiller and air handler power distribution.
- Versatile Wiring: 1-to-4 distribution per pole allows for clean, organized branching of power to multiple components.
- Dual-Conductor Compatibility: AL7CU rating enables safe termination of both copper and aluminum field wiring.
- Thermal Stability: Heavy-duty phenolic base prevents tracking and maintains structural integrity at high operating temperatures.
- Exact OEM Fit: Ensures proper mounting hole alignment and clearance for Carrier commercial HVAC equipment.
What wire size is required for the line and load sides?
The line side (primary) is designed for (1) 2/0 - #14 AWG wire per pole. The load side (secondary) features (4) openings per pole for #4 - #14 AWG conductors.
Is this terminal block compatible with aluminum wiring?
Yes, the tin-plated aluminum connectors are AL7CU rated, meaning they are approved for use with both copper and aluminum wiring at a 75°C connector rating.
Can I use this for delta or wye power configurations?
The 3-pole configuration makes this block ideal for standard three-phase power distribution systems common in industrial HVACR installations.
