TE Connectivity (TE) offers durable weatherproof shorting and open caps. Common uses include designating fixtures for maintenance, keeping lights continually on for safety (shorting cap).SC caps provide a convenient and economical method to close or open the primary circuit with a NEMA locking type receptacle. The MC-10 model also incorporates a 545 Joule Metal Oxide Varistor (MOV) that protects the cap and the luminaire from transient line surges.Designating ANSI in the part number will provide a unit with a steppedhousing dictated in the ANSI C136.10 specification. This unique housingmakes it easier for users to distinguish visually between a standard photocontrol and a shorting or open cap.
