4-4 SURGE PROTECTION
The Secondary Surge Suppression circuit consists of a special output filter comprising fuse-protected metal
oxide varistors and indicator lights. This option is designed to reduce the effect of load induced electrical noise
on other electronics such as connected loads. In addition, the secondary surge suppression circuit prevents
electronic and electromechanical devices from interfering with each other.
The characteristics of the filter assembly are as follows:
• Parallel (shunt) operation
• Response time of less than five nanoseconds
• Repetitive transient to 5,000 volts per second
• Clamping
voltage (208Y/120):
Ratio 1.2, 144 Vac line to neutral, 364 Vac line to line
Ratio 1.75, 210 Vac line to neutral, 364 Vac line to line
• Peak pulse power rating:
27 kW line to neutral
13.4 kW line to line
• Fused for circuit protection with visual blown fuse indicators (one per phase)
The secondary surge suppression circuit is factory installed at the time of production. No assembly or
adjustments are required.
4-5 MAIN INPUT CIRCUIT BREAKER, Phase Stabilizer (15 - 75 kVA)
The optional MAIN INPUT CIRCUIT BREAKER (IMCB) is used to switch power to the Phase Stabilizer unit ON
and OFF. The IMCB is located on the front panel of the unit, behind the hinged front door.
Be sure to observe ALL warnings and cautions when setting the IMCB to ON or OFF.
This option is factory installed at the time of production. No assembly or adjustments are required.
4-5-1 Main Input Circuit Breaker with Manual Reset Option.
This option prevents the circuit breaker from turning on once it trips due to over temperature or other critical
emergency turn off commands. The input circuit breaker will stay in the off position until the operator resets it
manually by pushing the reset switch and closing the input circuit breaker. The input circuit breaker can be
closed only after pushing the reset switch.
