This E-T-A 127-P10-H-KF-050022-3A is a single-pole thermal overcurrent circuit breaker. It utilizes a snap-action mechanism and is approved to EN 60934 standards. The breaker is designed for panel mounting and features a push-to-reset actuator.
Key electrical specifications include a voltage rating of 250 VAC or 28 VDC (UL: 250 VAC, 50 VDC) and a current rating of 3A. The interrupting capacity (Icn) is rated at 8 x IN for lower currents up to 2.5A, 20 x IN for 3A to 5A, 200A for 6A to 12A, and 300A for 13A to 25A. The UL 1077 interrupting capacity is 2,000A at 250 VAC and 2,500A at 50 VDC.
Environmental specifications include an operating temperature range of -20°C to +60°C and an IP40 degree of protection for the operating area. The optional -KF housing is noted as being suitable for high humidity conditions. Approvals include CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.
Typical applications for this type of circuit breaker include motors, transformers, solenoids, and battery chargers. The unit is designed for plug-in or integral mounting, track mounting, or with a frame for snap-in panel mounting.
