Overview
The Westinghouse EHB2015 is a thermal magnetic molded case circuit breaker designed for branch circuit protection in industrial and commercial electrical systems. Rated 15 amps, 2-pole, 240/480VAC, it delivers standard interrupting capacity of 14kA at 480V. This legacy breaker features bolt-on connection and long-time and instantaneous trip functions for reliable overcurrent and short-circuit protection.
Key Features
- Thermal Magnetic Protection: Long-time and instantaneous trip functions provide precise overcurrent and short-circuit protection.
- Molded Case Design: Durable, compact construction suitable for panel mounting in confined spaces.
- Bolt-On Connection: Fast, secure mounting to bus bar assemblies without additional hardware.
- 14kA Interrupting Rating: Meets standard capacity requirements for most industrial loads at 480V operation.
- Dual Voltage Rated: Operates at both 240V and 480VAC for flexible installation.
