Phenix HC40C – Circuit Breaker Test Set (40,000A out, 240V/380-480V Input)

Several versions available with varying voltage and current capacities. Please see the tables below for comparisons.

Notes:

• *** Input voltages, currents, and frequencies must be specified at order time ***
• *** AC power input wire and plug not included ***
• 50 Hz or 60 Hz must be specified
• Input currents based on 30-minute output ratings. Other input voltages are available, for example, 380 V, 50 Hz or 600 V, 60 Hz

Safety and Design Features

• Circuit breaker protection
• Control power switch with indicator and Output On indicator
• Interlock open indicator
• Emergency Off pushbutton
• Highly reliable SCR’s combined with programmable phase angle firing system
• Continuously variable output over entire test range utilizing a motorized vernier and programmable tap selector allowing for both auto-jog and current-hold capabilities
• Sensing circuit selectable between current or contacts
• Digital AC voltmeter for monitoring input, output, and external voltage up to 600 VAC
• Current meter accuracy 0.8% of reading +0.3% of range
• Meters calibrated with standards certified by NIST
• Standard HCSS1 and HCSS2 stab sets supplied with optional stab sets available
• Operation/maintenance manual

User-friendly, menu-driven commands provide advanced database and report capabilities for test duplication and recall, report generation, and current wave shape display.

• Normal – the operator manually controls all functions of the test set.
• Jog-to-Hold – the test set jogs the output on at “Jog on Cycles” and off for “Jog off Secs” and raises the output until the “Hold Amps” is reached.
• Jog-to-Trip – the test set jogs the output on at “Jog on Cycles” and off for “Jog off Secs” until the circuit breaker under test trips.
• Current Hold – the output is held to within 1% of the “Hold Amps”.
• Memory – used for testing the sensitivity pickup of electronic controllers (when the stop button is pressed, the current level is recalled).

This feature assures precisely repeatable current pulses with minimal distortion and DC offset. This is achieved by combining the use of highly reliable SCR’s and computer-controlled firing system.

This feature allows for viewing of the current wave form injected through the breaker. Detection of DC offset or contact bounce can be seen. With the use of the programmable phase angle firing circuit, DC offset may be corrected by varying the firing phase angle.
