The ACB Basic Functional Health Tester is designed for panel builders, electrical consumers, and maintenance teams who need a simple way to verify the basic operating health of Air Circuit Breakers during incoming inspection and preventive maintenance.

Purpose:

This tester is intended for practical workshop checks where the user wants to confirm that an ACB charges, closes, trips, releases where applicable, and provides correct status indication through NO/NC contact feedback.

Typical Applications:

• Incoming quality inspection of purchased ACBs before panel assembly
• Preventive maintenance checks of spare or removed ACBs
• Functional checking of ACB operation
• Verification of ACB status through NO/NC contact indication
• Maintenance workshop and panel shop use

Key Capabilities:

• Adjustable 0-440 VAC output for ACB control supply checks
• Digital AC voltmeter for output voltage monitoring
• Manual variac-based voltage setting
• Wired pendent control station for convenient operation near the breaker
• 1 NO and 1 NC front-panel ACB status indication
• Protected output circuits and workshop-grade construction

ACB Functions Supported:

• Spring charging motor operation check
• Closing coil operation check
• Shunt release / shunt trip operation check
• Undervoltage release check, where applicable
• ACB status contact indication check
• Trip indication and spring charged indication checks, where available

Pendent Control:

The wired pendent allows the operator to operate the ACB while observing the breaker mechanism directly. Typical pendent controls include Motor, Close, SR/Trip, UVR, and Emergency.

Technical Configuration:

• Dimensions: 19-inch rack-mount, 5U
• Input supply: 230 VAC, 1 phase, 50 Hz
• Output type: 0-440 VAC adjustable AC control supply
• Output measurement: Digital AC voltmeter
• Contact indication: 1 NO and 1 NC continuity input with front-panel ACB status indication
• Operator control: Wired pendent control station

The ACB Basic Functional Health Tester is useful for organisations that purchase ACBs, build electrical panels, and need a repeatable basic inspection and maintenance check without adding unnecessary testing complexity.
