LELHP/CELHP CIRCUIT PROTECTORS
The Airpax™ LELHP/CELHP high current magnetic circuit protector compliments our entire
series of LEL circuit protectors. Its unique, parallel current sensing design provides precise
current overload protection and reliability in the compact size of a two pole LEL. The unit
is ideal for high power DC applications such as drive motor systems and
telecommunication power systems.
It is available in series and series with auxiliary switch configurations with a choice of delays
for DC ratings of 125, 150, 175 and 200 amperes. The LELHP is UL listed under the conditions of
UL489 and CSA certified. The CELHP is UL listed under the conditions of UL489A. Mid-trip
handle indication, voltage trip and remote operator options complete the LELHP/CELHP circuit
breaker series. Please see the individual product tables for approved ratings.
