Product details

The nVent RAYCHEM Elexant 4010i electronic heat tracing control unit.  Elexant 4010i Series is a range of compact, full featured, touch screen based, single point heat tracing controllers, with ground fault protection. It provides control and monitoring for both freeze protection and process temperature maintenance. Available with either an electromechanical relay (EMR) for use in non hazardous areas, or solid state relay (SSR) for use in both non hazardous and ATEX/ IECEx Zone 2, Class I Div. 2  Zone 2 hazardous locations. Capable of controlling up to 32A at 277 V a.c. 

Available in 4 variants:

  1. Elexant 4010i-EMR-IS-FW (FRP enclosure - non hazardous locations only)
  2. Elexant 4010i-EMR-IS-SW (Stainless steel enclosure - non hazardous locations only)
  3. Elexant 4010i-SSR-IS-FW (FRP enclosure - hazardous areas ATEX/IECEx Zone 2)
  4. Elexant 4010i-SSR-IS-SW (Stainles steel enclosure - hazardous areas ATEX/IECEx Zone 2)

(All variants fitted with 25 cm x 20 cm window as standard)
