GE TED124020WL Molded Case Circuit Breaker 20A 2 Pole 480V AC

SKU CH-G57Q-E7K4V

A 20 A, two-pole molded case breaker rated for 480 V AC and 18 kA interrupting, thermal-magnetic trip, bolt-on mounting for GE panelboards

  • 20 A thermal-magnetic protection for reliable overload and short-circuit clearing
  • 18 kA interrupting rating at 480 V AC handles high fault currents
  • Bolt-on panelboard mounting fits GE TED-series panels directly
  • Two-pole design switches both lines in single-phase or two-phase circuits
  • Compact 6.31 × 2.75 × 4.09 in frame saves panel space

GE TED 20 A two-pole breaker

The GE TED124020WL is a molded-case circuit breaker rated 20 A at 480 V AC with an 18 kA interrupting rating at 120/240/277/480 V AC. It uses thermal-magnetic trip with fixed instantaneous settings and fits GE panelboards that accept the 150 A TED frame.

Compatibility checklist

Verify the panelboard accepts bolt-on TED-frame breakers and that the bus rating matches the 150 A frame size. Confirm the system voltage does not exceed 480 V AC or 250 V DC and that the available fault current is within the 18 kA AIR rating. Ensure the lug terminals suit the conductor size required by the circuit.

Build and mounting

The breaker measures 6.31 in high, 2.75 in wide and 4.09 in deep with bolt-on mounting for secure panelboard installation. Line and load lug terminals provide direct cable connection without additional hardware. The two-pole construction occupies two adjacent pole spaces in the panelboard.

Highlights

  • 20 A thermal-magnetic protection for reliable overload and short-circuit clearing
  • 18 kA interrupting rating at 480 V AC handles high fault currents
  • Bolt-on panelboard mounting fits GE TED-series panels directly
  • Two-pole design switches both lines in single-phase or two-phase circuits
  • Compact 6.31 × 2.75 × 4.09 in frame saves panel space

Questions about this item

What comes in the box and do I need to buy the lugs separately?

The breaker ships with the line and load lugs already fitted, so no separate lug purchase is required.

How do I choose between the 120/240/277/480 V AC ratings listed for the 18 kA interrupting capacity?

The 18 kA AIR rating applies at each of those voltages; select the breaker based on your system voltage, not the rating itself.

What does the 20 A trip rating mean once the breaker is installed in a 150 A frame panelboard?

It will carry up to 20 A continuously and trip on overload or short circuit, while the 150 A frame defines the maximum bus size it can mount on.
