This breaker is intended for use in compatible GE Q-Line bolt-on load centers and provides two-pole protection for multi-wire or 240V circuits.

Key Features

• 20 amp, 2-pole configuration for 120/240V circuits
• Bolt-on mounting designed for GE Q-Line panels
• 10 kA interrupting rating (10,000 A)
• Manufacturer: General Electric

What this breaker does

The THQB2120 is a two-pole circuit breaker that provides overcurrent protection for 120/240V branch circuits. As a 2-pole device, it simultaneously interrupts both ungrounded conductors for multi-wire or 240V loads.

• Protects 120/240V circuits requiring a 20A breaker
• Two-pole design trips both poles together

Electrical ratings and compatibility

Use the THQB2120 where a 20 amp, 2-pole breaker with a 10,000 A interrupt rating is acceptable and where the panel accepts GE Q-Line bolt-on breakers.

• Rated amperage: 20 A
• Poles: 2 (two-pole)
• Voltage: 120/240 VAC
• Interrupting rating: 10 kA (10,000 A)

Mounting and panel family

This is a bolt-on style breaker designed for GE Q-Line load centers. Confirm the panel type and physical breaker form factor before specifying as a replacement or for new installations.

• Mounting: bolt-on (Q-Line family)
• Intended for use in compatible General Electric Q-Line panels

Before You Order

Confirm the model number and quantity required before ordering. Verify panel compatibility and that a 20 A, 2-pole, 10 kA breaker meets the installation's electrical and code requirements.

• Match THQB2120 to the panel's Q-Line bolt-on form factor
• Confirm service voltage and required interrupting rating for the installation
• If replacing an existing breaker, compare the original part number and physical fit
