Protectowire PHSC-172-XCR Linear Heat Detector Cable, 172F Fixed Temperature, XCR Jacket

PHSC-172-XCR is Protectowire linear heat detector cable with a 172°F (78°C) fixed alarm temperature and an XCR fluoropolymer outer jacket. Two steel conductors insulated with a heat-sensitive polymer short together at the first point along the cable that reaches the rated temperature, which signals an alarm on the connected initiating circuit. The XCR jacket is the high performance version for industrial applications that need abrasion and chemical resistance, indoors or outdoors.
