42 Amps / 30.94 mH Current Limiting Reactor, P/N 6278CLR, Fault Current: 1200 Amps, High Voltage Application inside an oil filled enclosure

Product Overview

Current Limiting Reactors are used for line reactors, inrush current limiting, and surge current limiter applications. Current Limiting Reactors (CLR) develops a higher voltage drop across the CLRs when the current through the CLRs increases. Current limit reactors are gapped inductor intended to reduce the short circuit currents passing through the circuit breaker in the power system.

The photo of the inrush current limiter inside an oil filled enclosure, part number 6278CLR is shown below:

Medium Voltage CLR, Oil filled enclosure for P/N 6278CLR

Specifications:

• Current-Limiting Reactor, Oil filled, 42 Amps continuous, 60 Hz, P/N 6278CLR 
• Rating: 14000 VAC, 1 PH, 60 Hz, 42 amps continuous 
• Inductance: 30.94 mH ± 25%
• Fault current: 1200 Amps
• 490 VAC drop is estimated across the CLR at 42 amps continuous current. 
• When 42 amps increase momentarily to a catastrophic fault condition to 1200 A, CLR develops 14000 VAC across it. Eventually, the circuit breaker will trip and inhibit the fault condition. 
• Core is gapped. Without gap, core will saturate at 490 VAC voltage drop. With gap, the core will saturate at voltages higher than 490 VAC. 
• Oil filled enclosure: 6 feet H x 8 feet W x 5 feet D

The customer application of the Oil Filled CLR is shown below. The three fault limiting reactors are connected with the circuit breaker for power source protection.

The voltage drop across the fault current limiter at different current levels is shown in Table A:
