This E-T-A 127-P10-H-KF-7A is a single-pole thermal overcurrent circuit breaker designed for reliable circuit protection. It operates with a current rating of 7A and supports voltage ratings of 250VAC and 50VDC.
The breaker utilizes a thermal snap-action mechanism, offering a trip-free and tease-free operation. It is equipped with a push-to-reset actuator for easy manual reset after a trip event. The unit is designed for panel mounting, providing a secure and accessible installation.
Key technical specifications include an ambient operating temperature range of -20°C to +60°C. The operating area offers IP40 protection, while the terminal area is rated IP00. The breaker has undergone rigorous testing for vibration, shock, corrosion, and humidity resistance according to IEC standards.
Typical applications for this circuit breaker include protection for motors, transformers, solenoids, and battery charging systems, particularly in extra-low voltage applications. Its robust construction and thermal protection capabilities make it suitable for demanding environments.
The voltage rating is 250VAC, 28VDC (standard), and 50VDC (UL).
The current rating is 7A.
The operating ambient temperature range is -20°C to +60°C.
It uses a push-to-reset actuator.
It is approved to CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.
For 6-12A: 200A; for 13-25A: 300A. UL ratings: 2000A at 250VAC and 2500A at 50VDC.
