Applications
Ambient temperature control in professional premises where good protection against liquid splashes or dust is requested.
Output with 2 or 3 cable glands, allowing direct connection of heat tracing cables for freeze protection.
Housing: Reduced height, IP44, black PC-ABS fiberglass reinforced, UL94V0. High impact and UV resistance. 2 removable wall mounting lugs.
Cable input: M20 cable glands. Delivered with 2 or 3 cable glands. Special cable glands for oblong or flat heat tracing cables are available on request. Positioning the cable glands allows variations in the mounting position
Set point adjustment: By °C printed knob for external adjustment models, by screw driver and printed dial on internal adjustment models. °F values available in option
Sensing element: Liquid filled “pigtail” bulb, mounted on the side of plastic housing
Adjustment ranges: 4-40°C (40-105°F).
Electrical connections: On screw terminals. (It is possible to connect 2 wires 1.5mm² on each terminal). One main terminal and 3 auxiliary terminals are available for neutral connection. This allows, for example, connecting two heat trace heaters.
Mounting: Wall mounting, by two side lugs with holes for dia. 4mm screws, 69 mm distance.
Contact: SPNC (open on temperature rise).
Pilot light: Neon, 230V, standard in red, parallel connection on the load
