Lighting Contactors ASCO 920 which were developed for feeder circuits are great helpers on your enterprise! They have a lot of benefits, for example, they are very easy in the inventory and very quick in mounting. Additionaly, ASCO 920 Lighting Contactors for Feeder Circuits represents all-positional mounting.
These lighting contactors even have a special panel board lighting control. ASCO 920 have no power loss for high electrical surge loads. Furthermore, Lighting Contactors ASCO 920 have an anchored single-solenoid operator.
The model of Lighting Contactor ASCO 920 was created after the model ASCO 918 as a feeder disconnect switch for overload levels.
This item is available for limitary installations in NEMA-type bodies. Also ASCO 920 is available for direct installation within lighting panel boards for full or split-bus applications.
The ASCO 920 Lighting Contactor for feeder circuits is available from 30 to 225 amp per pole with 2-3 poles. Also, it should be mentioned, that it has service voltages to 600 VAC. ASCO 920 is in UL 50 listed under the number 8, what means that it was created for ballast lighting, tungsten, ohmic loads and also for general use, also it is UL-67 listed, what means it was created for current rating requirements for panelboard devices. Furthermore, it has the high endurance.
