Contactor circuits for distribution boxes typically range from $20 to $150 depending on type, current rating, and brand.

Types and Price Ranges

• Modular Contactors: Compact, DIN-rail mounted contactors suitable for residential, commercial, and industrial distribution boxes. Prices generally range from $20 to $80 depending on current rating and features such as overload protection and safety contacts .
• TPN (Three-Phase) Contactors: Designed for three-phase loads like motors, heating, and lighting circuits. These robust devices are priced higher, typically $50 to $150, depending on coil voltage, contact configuration, and manufacturer .
• Installation Contactors (Eaton examples): Single-phase or multi-contact contactors for distribution boards, with ratings like 20A and coil voltages from 8V to 230V AC/DC. Prices for these units usually fall in the $25 to $70 range .

Factors Affecting Price

1. Current Rating: Higher amperage contactors cost more due to larger contacts and stronger coils.
2. Coil Voltage: AC or DC coil voltage options can influence pricing.
3. Number of Contacts: Single, double, or multiple NO/NC contacts affect cost.
4. Brand and Certification: ABB, Eaton, and other reputable brands may be priced higher but offer reliability and compliance with safety standards .
5. Additional Features: Safety contactors, overload protection, and modular designs for easy installation can increase the price .

Summary

For a standard distribution box, expect to pay around $20–$80 for modular single-phase contactors and $50–$150 for three-phase or high-current TPN contactors. Always check the manufacturer's catalog or supplier for the most accurate pricing and availability, as prices may vary by region and supplier .
