Abstract
A chimney assembly is provided for an electrical switching apparatus, such as a circuit breaker including a housing and a number of poles. The chimney assembly includes a frame, an intake, a duct and an exhaust. A first side of the frame is coupled to the circuit breaker housing proximate the poles of the circuit breaker, and the intake and exhaust are respectively disposed at first and second ends of the frame. A first portion of the duct is coupled to the circuit breaker housing above the poles, and a second portion is coupled to the first side of the frame. The chimney assembly draws a volume of air through the intake into the circuit breaker housing, circulates the volume of air through the poles of the circuit breaker, and discharges the volume of air out of the circuit breaker housing through the duct and the exhaust.
