3120-N321-H7T1-W01D-15A Description

Short technical summary and product information.

The 3120-N321-H7T1-W01D-15A is a thermal circuit breaker engineered by E-T-A for industrial electrical protection applications. This component provides reliable overcurrent interruption within control panels and machinery power distribution networks.

 

Electrically, the unit operates at a maximum voltage of 415V and supports a continuous current rating of 15A. The two-pole configuration allows simultaneous disconnection of multiple conductors, ensuring comprehensive circuit isolation during fault conditions. The thermal trip mechanism responds to sustained overload temperatures, providing predictable protection without electronic complexity.

 

Mechanically, the device utilizes a standard panel mount footprint for secure enclosure integration. A rocker-style actuator enables manual switching and reset operations, while the absence of integrated illumination keeps the design streamlined for cost-sensitive installations.

 

The breaker carries multiple international safety certifications, including UL1077, IEC 60934, CSA C22.2 No 235, and GB 17701. These approvals verify compliance with equipment-level circuit protection standards across North American, European, and Asian markets.
