| ▪ Pushbutton and selector switch contacts are silver cadmium oxide which are "sealed" in lower phenolic chamber isolated from corrosive elements |
| ▪ N2 series is factory sealed, no external seals are required |
| ▪ The dust-tight construction means no magnesium dust enters the enclosure (after 32 hour UL test) |
| ▪ N2 series is molded of high-tensile 30% glass reinforced thermoplastic polyethermide |
| ▪ Enclosure walls are 5/16 in THK |
| ▪ Typical mechanical properties of 17000 psi tensile strength, 3% elongation at break, 27000 psi flexural strength and 1100000 psi flexural modulus |
| ▪ N2 series provides superior impact resistance, extremely low water absorption (this important quality assures dimensional stability), excellent resistance to ultraviolet light and water, superior flammability resistance and excellent pull-out resistance |
| ▪ 120 V pilot light (red standard) |
| ▪ Cover and box |
| ▪ 345 selector switch |
| ▪ Non-metallic construction with metal imbedded grounding grid |
| ▪ No need to install special wires and parts for grounding |
| ▪ Feed-through grounded 1/2 or 3/4 in conduit openings for threaded conduit |
| ▪ Special grounding wire furnished with each box provided |
| ▪ Non-metallic enclosures with corrosion resistant parts coated with epoxy, PTFE or Mylar™, these control stations offer unsurpassed resistance to chemicals |
| ▪ Silicone gasket, specially designed for the labyrinth-path point between cover and body, prevents entrance of moisture and dust |
| ▪ Smooth rounded integral bushing in each conduit opening protects conduct or insulation |
| ▪ Accurately tapped, tapered conduit openings for tight, rigid joints and ground continuity |
| ▪ Stainless steel pushbutton shaft operates within stainless steel bushing assuring long, maintenance free operation |
