The E-T-A 106-M3-PR-5A is a miniaturized, single-pole thermal circuit breaker with a push-to-reset, tease-free, trip-free, snap-action mechanism, conforming to EN 60934 (IEC 60934).
This circuit breaker is rated for 240V AC and 48V DC, with a current rating of 5A. It offers a degree of protection of IP 40 in the operating area and IP 00 at the terminal area. The device is designed for panel mounting.
Key electrical specifications include a rated impulse withstand voltage of 2.5 kV and a dielectric strength of 3,000 V AC. The insulation resistance is greater than 100 MΩ at DC 500 V. Interrupting capacity is 6 x IN for currents up to 2A and 5 x IN for currents from 2.5A to 10A.
Environmental specifications include an operating temperature range of -20°C to +60°C. The breaker has undergone vibration testing to IEC 60068-2-6 and shock testing to IEC 60068-2-27. It also meets requirements for corrosion and humidity resistance as per IEC 60068-2-11 and IEC 60068-2-3 respectively. The typical life varies based on current rating, ranging from 50 operations at 10A (2x IN) to 3,000 operations at 0.05-5A (2x IN).
The breaker is rated for 240VAC (datasheet) and 48VDC, with a UL rating of 250VAC. Interrupting capacity at 250VAC is 2000A, at 48VDC is 200A.
The 106-M3-PR-5A is rated for 5A continuous current.
The ambient operating temperature range is -20°C to +60°C.
According to UL 1077, the interrupting capacity is 2000A at 250VAC and 200A at 48VDC. For IEC ratings, it is 6xIN for 0.05-2A and 5xIN for 2.5-10A.
For currents up to 5A, the typical life is 3,000 operations at 2x rated current. For higher currents, life decreases: 6-8A at 500 operations, 10A at 50 operations.
The internal resistance at 5A is ≤0.05Ω.
The operating area is IP40, the terminal area is IP00.
