Model: AM03
Thermal cut-out AM03
Available
AM03 is a compact bimetal thermal cut-out designed for direct integration into motor windings, transformers and assemblies that require reliable temperature protection. The model operates at 250V AC with a rated current of 25A for resistive load and 12A for inductive load, with a 65°C–150°C switching temperature range and ±5K / ±10K tolerance. AM03 is suitable for electric motors, pumps, fans, transformers and industrial equipment where repeatable overheating protection, low contact resistance and easy serial-production assembly are important. VDE and UL approvals support use in B2B projects and export-oriented electrical devices.
