IE175VB Vacuum Circuit Breaker / Visual Disconnect  

Intermountain Electronics’ IE175VB vacuum circuit breakers combine a specially designed Visual Disconnect Switch (VDS) with an industry standard Vacuum Circuit Breaker (VCB) integrated into a single compact unit rated for 17.5kV operation up to 1250A.

These VDS/VCBs replace legacy 600A and 1200A designs with a globally accepted breaker and a high quality grounding VDS, while offering higher voltage and current ratings.

The VDS is opened or closed with an ergonomically designed actuating lever.  When the switch is in the open position, all 3 phases are grounded, and a mechanical interlock ensures that the VCB remains open.  The VDS can be padlocked/Kirk-locked in the open position.  Auxiliary switches are also provided for electrical monitoring/interlocking of the VDS switch position for additional safety.

The VCB provides front panel controls to open or close the VCB, and to charge the spring for manual operation.  In addition, the VCB has electrical open and close coils, along with a spring charging motor for remote operation to mitigate arc flash concerns.  The VCB includes 10 VCB auxiliary contacts, and a UVR option is available.

IE270VB Vacuum Circuit Breaker / Visual Disconnect  

The new IE270VB circuit breaker is the "big brother" to the IE175VB, and is rated at 27kV/600A.    

This product combines a specially designed Intermountain Electronics Visual Disconnect Switch (VDS), with an industry standard Vacuum Circuit Breaker (VCB) integrated into a single compact unit.  

The VDS can be opened or closed using an ergonomically designed operating lever on the front panel. When this lever is placed in the fully open position, all three phases (load side) are securely grounded, and a mechanical interlock ensures the VCB remains open.  The VDS provides front panel indicators and auxiliary contacts that actuate when the switch is fully open or fully closed.    

The VCB provides front panel controls and indicators to control the VCB.  Connections are also available for controlling and monitoring the VCB remotely, as well as ten sets of auxiliary contacts (five NC, five NO).  

The IE270VB is available with or without a Under-Voltage Relay (UVR).
