3120-F311-P7T1-W12X-3A Description

Short technical summary and product information.

The E-T-A 3120-F311-P7T1-W12X-3A is a single-pole thermal circuit breaker designed for overload protection of motors, pumps, transformers, and cables. It functions as an ON/OFF switch with integral overcurrent protection, utilizing a bimetal trip element.

 

Key electrical specifications include a current rating of 3A and voltage ratings of 250VAC and 50VDC. The breaker offers a rated voltage of AC 240V and DC 50V, with a current rating range from 0.1 to 20A. It is built to withstand vibration up to 8g and offers a dielectric strength of 3000 VAC between poles and 1500 VAC at the operating area. The insulation resistance is greater than 100 MΩ at DC 500V.

 

This circuit breaker is designed for panel mounting and features a rocker actuator. It has an operating temperature range of -30 to 60 °C. The degree of protection for the operating area is IP40, and for the terminal area, it is IP00 (or IP54/IP66 with a water splash cover).

 

Typical applications for this device include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools. It meets various approval standards including CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.
