The Sensata ATR20-A-63S-WB2-B-5.0A-2 is a single-pole, thermally operated circuit breaker designed for reliable current overload protection. It offers a current rating of 5A and voltage ratings of 250VAC (inductive/resistive) and 50VDC (resistive).
This thermal circuit protector features a trip-free operation mechanism activated by a reset button. It is designed for general industrial applications and includes a panel mount configuration for easy integration into equipment. The breaker has a maximum breaking capacity of 8x In for currents below 6A and 60A maximum for currents above 6A.
Key specifications include a rated short circuit capacity of a minimum of 6x In for AC and 4x In for DC, an insulation resistance of at least 100 MΩ at 500VDC, and a dielectric strength of 1.5 KV. The operational life is rated for 1000 cycles at 2x In. The maximum operating ambient temperature is 60°C.
The ATR20 series is RoHS compliant and suitable for various industrial control panels and power distribution systems where overcurrent protection is essential.
