Description:
- It’s a portable test set used to verify the operation of AC-PRO and AC-PRO-II trip units.
- It tests the pick-up and time delays of various protection functions by injecting current into the trip unit on the secondary side of the current transformer (CT) circuit.
- The B-292 can test AC-PRO trip units with frequencies of 25, 40, 50, or 60 Hertz.
- It can also test AC-PRO-II trip units set for either 50 or 60 Hertz.
- The test set evaluates the trip system, excluding the actual CTs and their wiring harness.
- It features a rugged, chemical-resistant, corrosion-resistant, and crush-proof ultra-high impact polypropylene shell.
- It often includes a telescoping handle and cable storage for portability.
Key Features:
- Tests pick-up and time delay characteristics.
- Compatible with various frequencies for AC-PRO trip units.
- Specifically designed for AC-PRO and AC-PRO-II trip units.
- Portable and rugged design for field use.
- Provides digital current and time displays.
