MIL-C-22992, Class L Part Builder
Application Standards/ Requirements
Class L Military MS90555 and Proprietary designations. Heavy duty, rugged, environmental cylindricals designed to meet the heaviest electrical loads for military or industrial applications. Current ranges of 40 to 200 amps, conductor sizes 6 to 4/0. Automatic grounding for safety. Qualified to MIL-C-22992. Within the controlled parameters of mil-spec - shell size relationship to current carrying capacity to reduce the possibility of inadequate wiring for heavy electrical loads.
Coupling/ Mounting Contact Termination
Double stub threaded per MIL-STD-1373 for fast coupling, easy cleaning. 5 key polarizing system assures that circuits with incompatible power characteristics (voltage, phase and frequency) are not mated. Rated to 500 complete mating/unmating cycles. Crimp termination.Contacts can be soldered.
Performance Environ./Elect. Markets
Operating temp. from –55°C to +125°C. Unique arc quenching capability provides a positive safety feature if connectors are inadvertently disconnected under load. Programmed coupling sequence - grounding and neutral contacts engage before power contacts. Grommets and seals provide waterproofing. Rugged shells are resistant to vibration, high impact, shock and corrosion.
