CLB-303-11B3A-B-A is a compact single-pole thermal circuit protector with push-to-reset functionality designed for overcurrent protection in household appliances, transportation, marine, and power supply applications. This device features a 3-ampere rating at 125-250VAC or 32VDC, with an interrupting capacity of 2500 amps at 32VDC and dielectric strength of 2500 VAC for 1 minute. The protector operates reliably across a temperature range of -10°C to 60°C with a voltage drop less than 0.25V, and maintains an insulation resistance of 100 megohms. It is UL, CUL, CSA, TUV, and CE approved, including UL1500/ISO8846 certification for ignition protection and marine applications. The M11 mounting hole configuration with Type A metal bushing and black button provides robust panel integration for demanding industrial and consumer applications.
