Dia. 30 to 70mm pipe-mounting thermostats, with 2 built-in pilot lights
This thermostat is designed with a V shaped temperature sensitive nickel plated brass backside to improve thermal contact with the pipe, and two lugs for spring mounting. Suitable for pipes of 30 to 70 mm diameter.
Housing: PC-ABS, fiberglass reinforced, UL94V0. High impact and UV resistance, with waterproof gasket on thermostat shaft for external adjustment types. Internal adjustment types have a PC transparent cover, to visualize the pilot lights and the set point adjustment.
Cable input: ISO M20 cable gland, Black PA66, IP67, for cables from 6 to 12 mm dia.
Set point adjustment: By °C printed knob for external adjustment models, by screw driver and printed dial on internal adjustment models.. External adjustment types have an adjustable rotation limit system located inside the knob that allows reducing the set point adjustment span. °F values are available in option.
Sensing element: Liquid filled capillary , inside the nickel plated brass part in contact with the pipe.
Adjustment ranges: 30-90°C (85-195°F), 30-110°C (85-230°F)
Pilot lights: Allow to visualize the power supply and thermostat contact
position (Phase and Neutral power supply is mandatory for pilot lights) .
Electrical connections: On screw terminals. (It is possible to connect 2 wires 1.5mm² on each terminal). In option, an auxiliary connection block can be added, providing 3 neutral terminals.
Mounting: By spring on pipe.
Contact: SPNC (open on temperature rise).
Electrical rating, resistive loads:
16A 250V, 50 ~60Hz: >100000 cycles,
20A 250V, 50 ~60Hz: ≥ 50000 cycles,
