Adjustable Test Stab Set Maximum Flexibility for Circuit Breaker Testing

The ETI adjustable test stab set can reduce testing time on large projects with multiple breakers by as much as 30%.

The ETI adjustable test stab set may be used with your high-current circuit breaker testers to maximize efficiency and convenience for testing multiple breakers. Our stab system allows your technicians to test breakers in-place and avoid jacking breakers up or down for testing. By combining mobility and flexibility into one simple system, this stab set is a proven improvement over conventional designs. The components in the adjustable stab set are made of 120 pounds of 110 copper.

The ETI universal adjustable test stab system includes:

  • Scissor Adjustable Arms that can be used in any configuration to meet your requirements. A 2 & 1 setup is great for offset fused breakers such as the GE AKU’s.
  • .25″ shims used to increase the stab thickness from .50″ to .75″ for both the vertical and horizontal stabs.
  • Horizontal stabs for smaller air power circuit breakers such as the Westinghouse DB-15 and DB-25.
  • Horizontal stabs with .25″ shims for larger air power circuit breakers such as Westinghouse DB-50, DB-75, DB-100 and GE AK-50.
  • Vertical stabs for smaller air power circuit breakers such as Westinghouse DS-206 and DS-416 and Siemens RL-800 and RL-1600.
  • Vertical stabs with .25″ shims for larger air power circuit breakers such as the Westinghouse DS-632 and DS-420.
  • 2″, 3″, &am; 3-5/8″ Large round stabs for round configured connections such as the ITE K-line 2000A and above.
  • Stabs used to connect to any mechanical lug – great for testing molded case breakers.
  • Mounting brackets to accommodate ETI, Multi-Amp, AVO, Megger circuit breaker testers.
