Applications

Manual reset safety thermostats, for applications where there are risks of condensation or water drops. The thermostat body, including the cup crimping zone, is inside an epoxy potting. The manual reset button is accessible by a small silicone cap partially embedded in the epoxy resin. The 2 wires output, in addition to protection against ingress of water, also protects users against accidental contact with live terminals.

Main features

Thermostat Housing: High temperature black epoxy, diameter 16.2 mm. Good UV resistance. Excellent wire pull strength. Maximum ambient temperature 120 °C.

Temperature sensing cup: Stainless steel, not over-molded to improve temperature measurement. (Achievable in aluminum on request)

Contact: SPNC, open on temperature rise.

Reset: Manual

Electrical rating: 10A resistive, 250VAC, 1000 cycles.

Wires: XLPE insulated, 300V, AWG16 (1.5mm²), stranded, temperature resistance 125°C, according to UL3266.

Wire terminations: Stripped on 6mm (wire end terminals or other terminals on request)

Calibration temperatures: Available on request from 40 to 120°C. Standard tolerances +/- 5 ° C.

MOQ 1000 pieces applicable for specific values.

Product identification: Reference label on the wires and coded date on the thermostat cup

Mounting: Two modes: flat bracket (type A) for measuring surface temperature, or extended cup bracket ( type B) for through wall measurement .Main references with 1 meter wires, T125°C XLPE, AWG16 (1.5mm²).

Technical informations associated to this product

  • Electrical contacts

    As numerous mechanisms exist, we decided not to distinguish on the basis of constructive technique, but according to their operation speed, which is the key element.

  • Electrical protection classes

    The housings are designed to protect electrical equipment located inside. This protection must be considered in the electrical and environmental angles.)

  • Description of temperature controls

    Used as control thermostats or as a safety thermostat with manual reset, these thermostats have a disc made of two different metals laminated together for temperature sensing element. These two metals have different expansion coefficients.
