Document Type and Number:
Japanese Patent JPH0528902
Kind Code:
A
Abstract:
PURPOSE: To reduce the rate of temperature rise of each contact using simple means without enlarging the conductor of each electrically conductive portion.
CONSTITUTION: A current limiter 2 having current-limiter side switching portions 10-17 comprising more than one pair of contacts is mounted on a circuit breaker 1 having breaker side switching portions 5-8 having one pair of contacts per pole. A heat conducting bypass member 20 is provided for allowing heat to dissipate to a current-limiter side terminal portion 3 from the breaker side switching portions 5-8 without passing through the current-limiter side switching portions 10-17.
