IEEE PC37.13.1 DRAFT
Draft Standard for Definite-Purpose Switching Devices for Use in Metal-Enclosed Low-Voltage (600 V ac and Below) Power Circuit Breaker Switchgear
|Publication Date:||1 October 2015|
This standard provides requirements for low-voltage (600 V ac and below) definite-purpose switching (LV 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. These switching devices may be used in motor control or other repetitive duty applications and have the following characteristics:
a) Drawout type, three-pole construction
b) Integral current-limiting fuses for short-circuit protection
c) Power operated, with integral or separately mounted overcurrent protective devices
In this standard, the term "LV-DPS device" denotes a low voltage definite-purpose switching device conforming to the requirements of this standard.
This standard provides guidance in evaluating switching devices, other than low-voltage power circuit breakers conforming to IEEE Std C37.13™, that are intended to be applied in metal-enclosed, low-voltage power circuit breaker switchgear.
