TEYF3015B - 15Amp Circuit Breaker

TEYF3015B - 15 Amp Circuit Breaker

The TEYF3015B is a 3-pole, 15-amp bolt-on circuit breaker used to protect your three-phase electrical circuits from overloads and short circuits. It features a thermal-magnetic trip unit with a non-interchangeable 15-amp trip, making it a good fit for installations where a fixed trip setting is required. The bolt-on design creates a secure connection to compatible panelboards, helping you reduce movement over time.

This breaker is built for 480Y/277V electrical systems and carries an interrupting rating of 18 kA at 480 VAC and 65 kA at 240 VAC. It's commonly installed in commercial buildings, industrial facilities, and other applications that use three-phase power. Whether you're replacing an existing breaker during maintenance or matching equipment specifications, the TEYF3015B provides the electrical protection expected for its rating without adding unnecessary complexity.
