The Eaton Breaker Type Bypass Isolation Transfer Switch is designed for applications where preventative maintenance,
inspection and testing must be accomplished while maintaining continuity of power to the load. Proven switch designs ensure
reliable transfer from normal to auxiliary power sources for rapid restoration of essential power in critical
Superior Main Contact Structure
Transfer Switch is Easy to Maintain and Test
- The Eaton Combination Breaker Type Bypass and Automatic Transfer Switch is listed to CSA specifications C22.2 #178 and
- As an added plus the switching devices are listed under CSA C22.2 #5. Completely enclosed contacts provide both safety
and reliability. They also ensure the integrity of the contact assemblies and minimize the need for periodic maintenance of
the contacts, reducing the need for downtime and maintenance time.
The Eaton Breaker Type Bypass Isolation Switch is designed to require minimum maintenance even under the most strenuous of
operating conditions. Due to the use of moulded case switches and their inherent self-protection capability, the contact
structure and mechanism is extremely long lived.
Our experience has shown that through normal operating conditions, the moving and stationary contacts will maintain their
integrity for the full expected life of the transfer switch. When isolating and bypassing the transfer switch, a short term
(less than 3 second) power interruption results. However, this is less than when transferring power after a power outage
using a standard transfer switch. Also, with a double-sided bypass the transfer switch can be bypassed to either source
quickly and easily regardless of the position or condition of the transfer switch.
Safety to Maintenance Personnel
In most instances, the Breaker Type Bypass Isolation Switch will be in the Bypass Mode only during a maintenance or testing
period. During this time, there could be operating personnel close to the equipment. The self protection capability of the
Eaton switch would give these operators an extra measure of safety during a rare coincidental fault condition.
The Eaton Breaker Type Bypass Isolation Switch is available with all the options and features of our standard Transfer Switch
product line. Proven, microprocessor based programmable controllers are supplied as standard on all Breaker Type Bypass
