ETI PI-6000 Circuit Breaker Test Set

Overview

The ETI PI-6000 is a versatile primary injection test set for testing low-voltage molded-case and metal-clad AC circuit breakers up to 6,000 amperes frame size. Constructed in a rugged steel enclosure with removable sides and full-width handles, the unit is engineered for reliability, durability, and ease of use. The system operates on either 208-240VAC or 480VAC power sources and can also be used for high-current applications such as ratio transformer testing and heat runs.

Key Features

• Dual input/output transformer with separate primaries for 480VAC and 208-240VAC operation
• Dual secondary windings for optimal impedance matching across circuit breaker sizes
• MAC-21 advanced controller with industry-leading accuracy and manual/motorized vernier with LED indicator
• Digitally controlled SCR initiation providing zero DC offset and eliminating closing time errors
• Temperature protection with interlock shutdown for both output bus and vernier Powerstat
• Serial port interface (9600 baud, 8-bit) for data logging and result export to printers or computers
• Preset pulse mode for cycles or seconds up to 9999 seconds duration
• Locking swivel castors on all four corners for easy mobility
• High interrupting current capacity input fuses for primary protection

Applications

• Testing low-voltage molded-case AC circuit breakers from multiple manufacturers
• Testing metal-clad AC circuit breakers
• Electro-mechanical and solid-state trip device testing
• Instantaneous and short-delay trip verification
• Ratio transformer testing
• Heat runs on cables and electrical devices
