Overview
The Westinghouse EHB2015 is a thermal magnetic molded case circuit breaker designed for industrial and commercial electrical distribution. This 2-pole unit delivers reliable overload and short-circuit protection across 15A and 480VAC ratings. With bolt-on connectivity and load-side lug terminals, it integrates easily into existing panel layouts. Though discontinued by the manufacturer, the EHB2015 remains available through surplus stock channels and is suitable for replacement or retrofit applications where original specifications must be maintained.
Key Features
- 15A rated current with 480VAC maximum operating voltage
- Thermal-magnetic trip mechanism for both overload and instantaneous short-circuit protection
- 14kA interrupting capacity at 480V, standard for industrial branch circuits
- Bolt-on mounting to panelboard for secure installation
- Long-time and instantaneous trip functions (LI trip characteristic)
- Load-side lug terminals for simplified field wiring
