HED43B015L - 15Amp Circuit Breaker

HED43B015L - 15Amp Circuit Breaker

The Siemens HED43B015L is a 15 Amp, 3-pole molded case circuit breaker from the SENTRON ED frame family. Designed for 480VAC electrical distribution systems, it combines thermal and magnetic trip protection to help safeguard equipment against overloads and short circuits. Its 42kA interrupting capacity at 480VAC makes it suitable for applications where higher fault current ratings are required.

Whether you're replacing an existing breaker during maintenance or keeping compatible spare inventory on hand, the HED43B015L is intended to match the original equipment's form, fit, and function.
