The E-100-A and E-100-L-A serve as above-insulation end seal kits for Raychem brand BTV, QTVR, XTV, KTV, or VPL heating cables. They are approved by FM and CSA for use in hazardous locations. Both the E-100-A and the E-100-L-A are mounted on the pipe and project through the thermal insulation and cladding for ease of maintenance. The E-100-L-A end seal with signal light uses an array of bright LEDs for exceptional visibility and long product life. These rugged end seals are made from high-performance engineering polymer and resist impact, high temperature, and chemical and UV exposure. The stand allows for up to four inches (100 mm) of thermal insulation. The encapsulated light and boot reliably prevent moisture and dust ingress. The industrial-grade electronics used in the E-100-L-A are encapsulated. Both the E-100-A and E-100-L-A are re-enterable, allowing easy access for testing. Voltage and continuity checks can be done by simply unscrewing the E-100-A cap and removing the reusable sealing boot. The E-100-L-A makes maintenance even easier by allowing for visual inspection of heating circuit continuity. The E-100-L-A can be retrofitted into previously installed E-100-A end seals. The light module is replaceable. The kits contain all the necessary materials for a complete installation except for one pipe strap, which must be ordered separately.
