Eaton EHD2020 Molded Case Circuit Breaker 20A 2 Pole 480V AC

SKU CH-TCZX-EG3JB

A 20 A, two-pole molded case breaker with thermal-magnetic trip rated for 480 V AC and 250 V DC

  • 20 A rating protects 480 V AC circuits
  • Thermal-magnetic trip responds to overloads and short circuits
  • Fixed instantaneous trip at 100 A limits peak let-through
  • 18 kA interrupting at 240 V AC clears heavy faults
  • Lug terminals on load side speed panel wiring

Eaton EHD2020 20A 2-Pole Breaker

The Eaton EHD2020 is a molded case circuit breaker rated at 20 amps with two poles for 480V AC systems. It uses thermal-magnetic trip technology with fixed instantaneous settings and a standard trip type. The unit carries an 18kA interrupting rating at 240V AC and supports DC voltages up to 250V. Load-side lug terminals simplify wiring in compatible enclosures.

Suited for panel builders using Allen Bradley

This breaker fits Rockwell Automation enclosed control gear, Westinghouse switchboards and Eaton motor control centers where a 20A two-pole device is specified. It is not for installers who need adjustable instantaneous trip curves or higher interrupting capacities beyond the listed 18kA at 240V AC. Buyers requiring three-pole configurations or different ampere ratings must select another model.

Ships as a single breaker with lug terminals

The package provides the molded case unit with load-side lugs ready for conductor termination. No additional mounting hardware, shunt trips or auxiliary contacts are included. The fixed thermal-magnetic calibration means no field-adjustable accessories are required or supported for the trip settings of 10A low and 100A high.

Questions about this item

What panel or enclosure does the EHD2020 bolt into?

It is listed for use with Allen Bradley MCC, Eaton MCC, Rockwell Automation Enclosed Control, switchboard and Westinghouse equipment.

Will the 480 V AC rating protect my existing 240 V AC circuits?

The breaker carries an 18 kA interrupting rating at 240 V AC and a 480 V AC voltage rating, so it can be applied on 240 V systems within that AIR.

How do I verify the thermal-magnetic trip is operating correctly?

The fixed instantaneous trip and adjustable range of 10 A to 100 A mean the breaker should open on sustained over-current above the dial setting and on short-circuit current per the 18 kA rating at 240 V AC.
