Product Overview | 4051 ERA Igniters
ERA igniters are intended for use in systems that require sealed ignition wiring. They have a ¾ -20 threaded igniter connection for sealed air-craft type ignition wiring, and are intended for Class 1 Div. 2 applications. Although the wiring method used between the ignition transformerand the spark plug was designed and chosen to be suitable for use in Class 1 Div. 2 hazardous locations, it DOES NOT carry certifications or third party approvals. Standard 6000 volt transformers and 4085-ERA ignition cables are used with these igniters. Spark should be shut off after lighting. ERA IGNITERS

Except for the electrode connection all other dimensions and igniter functions are the same as the regular 4051 igniters. At this time the “A” size 4051 is not available in the ERA style.
