Instrodots CBF01 Circuit Breaker Finder with GFCI Tester & Accessories – 90-135V AC

Overview

The Instrodots CBF01 Circuit Breaker Finder Tool is your practical companion for electrical troubleshooting. Compatible with standard 90-135V AC systems, it blends a transmitter and receiver with a color display and audible cues to guide you to the right breaker. The integrated GFCI outlet tester adds a safety check that can reveal trip timing and common wiring conditions, helping you explore circuits with more confidence.

Smart two-part identification

Say goodbye to guesswork. The two-piece transmitter–receiver workflow makes circuit mapping straightforward. Plug the transmitter into an outlet or fixture, then use the receiver to scan your panel and identify the correct breaker in minutes.

• Three-step process: plug, scan, confirm
• No fiddly sensitivity dials to adjust
• Works across typical residential and commercial layouts

Clear visual and audible cues

The transmitter offers a bright color display to show status at a glance, while the receiver uses an analog bar and a reliable audible alert. This combo helps you distinguish the targeted breaker even in dim spaces or crowded panels.

• Green and red signals streamline decision-making
• Audible alerts complement on-screen feedback

Built-in GFCI testing

Use the transmitter as a standalone GFCI tester to verify trip time and overall function. This capability supports safer troubleshooting by quickly checking a common protective device.

• Tests GFCI trip timing in seconds
• Auto-hold feature helps reach difficult outlets

Durability, safety, and portability

Rugged construction with anti-dust and anti-drop protection keeps up with field use. Automatic power-off and low-battery alerts simplify maintenance, and a dedicated carrying case makes transport and storage easy.
