The E-T-A 3120-N551-PTT1-W02D-20A is a thermal circuit breaker that combines overcurrent protection with the function of an ON/OFF switch. It utilizes a bimetal trip element and is suitable for overload protection of motors, pumps, transformers, and cables. This 2-pole breaker has a nominal current rating of 20A and can operate at up to 240V AC or 50V DC.
Designed for panel mounting with a rocker actuator, this circuit breaker offers reliable disconnection and easy resettability. Its features include a positively trip-free mechanism, ensuring circuit disconnection even with a blocked actuator. The internal resistance per pole is typically less than 0.02 Ohms at 20A.
Typical applications for this thermal circuit breaker include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, and audio equipment. It is also suitable for use in medical equipment according to IEC/EN 60601.
Compliance information indicates RoHS3 compliance, REACH unaffected status, and an MSL of 1 Unlimited. Approval agencies include CSA, KTL, UL, and VDE.
