This E-T-A 127-P10-H-KF-12A is a single-pole thermal overcurrent circuit breaker, part of the 127 series. It is designed with a push-to-reset, trip-free, snap-action mechanism, suitable for various applications including motors, transformers, and solenoids.
The circuit breaker has a voltage rating of 250V AC and 50V DC (UL rated), with a current rating of 12A. It is approved by CSA, GB, IEC, and UL standards. The device offers a degree of protection of IP40 in the operating area and IP00 at the terminals.
Designed for panel mounting, this thermal circuit breaker operates within an ambient temperature range of -20°C to +60°C. Its robust construction is tested for vibration, shock, corrosion, and humidity resistance, making it suitable for demanding environments. The optional -KF housing is particularly suited to high humidity and other damp conditions.
It is rated for 250VAC and 50VDC (UL), with an additional 28VDC rating from the datasheet.
The ambient operating temperature range is -20°C to +60°C.
Panel mount.
The interrupting capacity is 200A for 6-12A versions (IEC) and 300A for 13-25A (IEC). Under UL 1077, it is 2000A at 250VAC and 2500A at 50VDC.
It is approved to CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.
5,000 operations at 2x rated current (inductive for 0.05-16A, resistive for 17-25A).
IP40 on operating area, IP00 on terminal area.
