Product Description

        


 

1.Introduction

ZW32-15KV/27KV/38KV Outdoor Dead Tank Vacuum Circuit Breaker is designed to meet all applicable ANSI, NEMA and IEEE standards.

ANSI/IEEE C37.04-1999 rating structure for ac high-voltage circuit breakers

ANSI/IEEE C37.06-2009 preferred ratings ac high-voltage circuit breakers

ANSI/IEEE C37.09-1999 test procedure for ac high-voltage circuit breakers

NEMA SG4-2009 ac high-voltage circuit breakers.

 

2.Magnetic-actuator operator features:

Design adapted from type TD stored-energy operator configuration, High-voltage compartment configuration identical to stored energy version

Design tested to ANSI/IEEE C37.09, Built-in fast discharge circuit for electronic controller power capacitors

Manual opening handle requires very modest force for operation,  Electronic controller life estimated at 30 years.
