Abstract:
This amendment to the standard revises the short-circuit rating and test requirements for definite-purpose switching devices for use in metal-enclosed low-voltage power circuit breaker switchgear.
Scope:
The scope of this standard is to provide requirements for low-voltage (600 V (ac) and below) definite purpose switching (DPS) devices (other than power circuit breakers) for use in metal-enclosed, low-voltage, power circuit breaker switchgear described in IEEE Std C37.20.1(TM)-2002. These switching devices may be used in motor control or other repetitive duty applications and have the following characteristics: Drawout type, three-pole construction; Integral current limiting fuses for short-circuit protection; Power operated, with integral or separately mounted overcurrent protective device. The term "DPS device" will be used in this document to denote a definite-purpose switching device conforming to the requirements of this standard.
