ASCO 7000 Series Transfer Switches Soft Load - Switch Types

Closed Transition Soft Load Power Transfer Switching Closed Transition Soft Load Power Transfer Switching

ASCO 7000 Series Closed-Transition Soft Load Power Transfer Switch,
rated 3000 amps in a Type 3R outdoor enclosure typically used with a 2MW gen-set.

Both the Closed-transition Soft load power Transfer Switch and the Bypass-Isolation Soft Load Power Transfer Switch feature identical electrical ratings and heavy duty mechanical interlocks that assure proper operation. The transfer switches feature a family of innovative electronic components that help make the switches the most advanced in the world.

ASCO power transfer switches - the standard of the industry - synchronize and parallel generation and utility power, allowing critical load transfers without momentary outages or surges.

Overlapping main electrical contacts, using a reliable and field-proven solenoid operating mechanism, enable make-before-break transfers that help ensure continuous power. Control logic continuously monitors power source conditions and automatically determines whether the load transfer should be open (conventional, non-overlapping mode) or closed transition. Failure to synchronize indication and extended parallel time protection is built in to prevent abnormal operation.

7000 Series power transfer switches are available in ampacity sized of 150 through 4000.

Soft Load Power Transfer Switch with Bypass-Isolation Soft Load Power Transfer Switch with Bypass-Isolation

ASCO 7000 Series Soft Load Power Transfer Switch with bypass-isolation, rated 2000 amps in a Type 3R outdoor enclosure.

The ASCO 7000 Series Closed-Transition Soft Load Power transfer Switch with bypass-isolation switching allows the switch to be inspected, tested and maintained without interrupting power, whether it's being provided from the utility or onsite generator.

A draw-out mechanism power transfer switch helps ensure ease of service and maintenance. Simple bypass and isolation functions require only two operating handles. Bypass contacts carry current only during the bypass mode.

The bypass switch has dead front quick-make, quick-break operation for transferring loads between live sources. It is fully rated for use as a manual three-position emergency power transfer switch in the event of a utility power failure when the transfer switch is in the isolated position. It is available in ampacity sizes of 150 through 4000.
