Product catalog summary

Overview: This document outlines the specifications and ordering information for thermal protectors used in electrical systems. These devices are designed for automatic resetting and come in various configurations with distinct features.

Specifications:

Contact Type: Available in normally closed (NC) and normally open (NO) options.
Nominal Switching Temperature (NST): Ranges from 60°C to 200°C with a tolerance of ±5K or ±10K.
Reset Temperature Range: Varies based on NST, with specific ranges for some models.
Operating Voltage: Up to 500V AC/DC, with some models supporting up to 480V.
Rated Voltage: Typically 250V (VDE) and 277V (UL).
Rated Current: From 2.5A to 42A, depending on load type and switching cycles.
Contact Bounce Time: Less than 1 ms for all models.
Contact Resistance: Less than 50 mW as per MIL-Std. R 5757.
Vibration Proof: Rated at 100 m/s² for frequencies between 10 to 60 Hz.
Pressure Stability: Between 300N to 600N, model-dependent.
High Voltage Insulation: Up to 2 kV for most models.
Approvals: Certified by IEC, VDE, UL, CSA, and CQC.

Ordering Information: Instructions are provided for ordering thermal protectors, specifying type, version, switching temperature, tolerance, and lead length. Deviations from standard guidelines are not inspected for usability or conformity.

Additional Notes: Special switches are available upon request, and technical changes may occur. Illustrations are to scale, and guidelines for part usage are included.

PTC Thermistor Sensors:

Insulation Material: Options include Mylar-Nomex, Kynar, and Teflon.
Nominal Response Temperature: Ranges from 70°C to 180°C.
Operating Voltage: 2.5 VDC to 30 VDC, with a maximum recommended sensor voltage of 7.5 VDC.
High Voltage Insulation: 2.5 kV across all models.
Dimensions: Insulation cap length is 12.0 mm, diameter ≤ 3.0 mm.

General Characteristics: Temperature-resistance diagrams and color-coding for nominal response temperatures are provided, along with detailed temperature range and resistance specifications.
