MARRETTE® BLACK FOR HIGH TEMPERATURE WIRE CONNECTORS
When ambient temperature is a design constraint: Marrette Black is rated and ready for high-wattage fixtures, commercial signage, and elevated-temperature installations.
RATED FOR THE HEAT
When electrical connections must perform reliably in elevated-temperature environments, the Marrette Black high temperature wire connector is the solution. Rated to 150°C (302°F), its rugged thermoplastic polymer cap is designed for use in high-wattage lighting fixtures, signs, and other heat-intensive applications where a standard connector is not rated for service. The large, finely ribbed barrel-shaped cap provides a secure grip, and the threaded entry guides wire bundles into the internal conical spring chamber. The conical spring multiplies applied torque through leverage and wedge action, creating a firm conductor joint. Model 30 Black is approved for circuit and fixture connections up to 300 V only. Models 31, 33, and 35 Black are approved for circuits up to 600 V and lighting fixtures and signs up to 1,000 V. For copper conductors only.
KEY FEATURES AND BENEFITS
<p>When the environment runs hot, standard connectors are not enough. The Marrette Black high temperature wire connector is rated to 150°C and purpose-built for high-wattage lighting fixtures, commercial signs, and other elevated-temperature applications where connection integrity cannot be compromised.</p>
150°C-Rated thermoplastic polymer cap
<p>Withstands sustained elevated ambient temperatures in high-wattage fixture housings, commercial signs, and industrial luminaire environments.</p>Conical spring torque multiplication
<p>Internal conical spring uses leverage and wedge action to multiply applied torque, creating a firm, stable conductor joint.</p>Copper-coated spring
<p>Corrosion-resistant spring coating extends connection reliability in the moist or chemically variable environments sometimes found within fixture enclosures.</p>Barrel-grip cap design
<p>Large, finely ribbed barrel cap provides grip in hot, greasy, or confined installation conditions common during fixture servicing.</p>Model-specific voltage ratings
<p>Model 30 up to 300 V. Models 31, 33, 35 up to 600 V (circuits) and 1,000 V (lighting fixtures and signs). Always select the correct model for the application voltage.</p>INDUSTRIES WE SUPPORT
