Overview

The ABB TEYD1050B is a 1-inch wide per pole, compact bolt-on circuit breaker engineered for grounded 480Y/277 Vac systems. This single-pole breaker delivers a 50 Amp current rating with a 25kA interrupting capacity, making it ideal for industrial and commercial electrical distribution applications. The TEYD1050B is part of ABB's TEY series, designed for use in lighting panelboards, including ABB A-Series units, where space efficiency and reliable performance are critical. Key specifications include Quick-make/Quick-break mechanisms for rapid fault interruption, reducing arc flash hazards and protecting downstream equipment. The breaker features a common trip bar to ensure simultaneous tripping across all poles during fault conditions, enhancing system safety. A highly visible trip indicator provides immediate visual confirmation of breaker status, enabling faster troubleshooting and minimizing operational downtime. The TEYD series offers modularity with 1, 2, and 3-pole configurations. While the TEYD1050B is a 1-pole unit, 2- and 3-pole versions support optional accessories such as auxiliary contacts for remote signaling, shunt trip units for remote tripping, undervoltage releases for voltage fluctuation protection, and bell alarms for audible fault notification. This flexibility allows tailored solutions for specific system requirements. The TEYD1050B is compatible with bolt-on mounting base accessories (TEY3B or TEY3B125) for unit mount or lug-lug connected applications. It is UL listed for Heating, Air Conditioning, Refrigeration (HACR) and High-Intensity Discharge (HID) applications up to 50A. The breaker is manufactured in the USA, adhering to ABB's quality and reliability standards for critical power distribution circuits.
