Overview

The TE Connectivity 3-1393250-1 is a Potter & Brumfield W28 series thermal circuit breaker engineered for precise overcurrent protection in industrial and commercial applications. This single-pole breaker delivers reliable performance with a 16A current rating and supports operating voltages of 250VAC and 32VDC, making it ideal for control panels, machinery, and power distribution systems. The series trip mechanism ensures consistent circuit interruption when current exceeds the rated limit, preventing damage to connected equipment. With a compact black housing, it integrates seamlessly into existing setups while maintaining durability and long-term reliability. The 3-1393250-1 is designed for applications requiring thermal tripping characteristics, offering a cost-effective solution with a 16A rating and compatibility with both AC and DC systems. Its compact design and durable construction make it suitable for harsh environments where reliable operation is critical. The breaker is manufactured in the USA and carries the UNSPSC code 39121601 for easy procurement and classification. This circuit breaker is part of the Potter & Brumfield W28 series, known for its thermal protection capabilities and robust performance in industrial settings. The 16A current rating ensures it can handle moderate loads while providing essential overcurrent protection. The 250VAC and 32VDC operating voltages make it versatile for a wide range of applications, including control panels, machinery, and power distribution systems. The series trip mechanism activates when the current exceeds 16A, interrupting the circuit to prevent equipment damage. The black housing is designed for durability and easy integration into existing systems, while the compact size allows for installation in tight spaces. The breaker meets industry standards for circuit protection, ensuring compliance with safety and performance requirements. Its long-term reliability and cost-effectiveness make it a preferred choice for applications where thermal tripping is essential. The UNSPSC code 39121601 further simplifies procurement and classification in industrial supply chains.
