Square D Micrologic Trip Units

ETC-12 vs Micrologic Series 1, Series 2, Series 3, Series A

seKit_frontViewDo you need a repair or replacement of a Square D Micrologic Protection Unit? ETC-12 has the solution. Many of the Micrologic trip units are obsolete and nearing end of life. Fortunately, the ETC-12 replacement for the Micrologic trip unit is designed to replace the Micrologic protection unit in the SE Family (SED/SEF breakers). The ETC-12 is a one-box fits all device in that the ETC-12 will replace a Micrologic control unit on any SED or SEF breaker frame size (800A, 1200A, 1600A, 2000A, 2500A, 3000A and 4000A).

The ETC-12 seamlessly installs into the frame where the Micrologic is removed.  The ETC-12 kit eliminates the need for pesky rating plugs. Instead, through the simplified digital setup menu on the “ETC-UI” the operator can seamlessly set the breaker to trip anywhere from 25%-100% of the breaker’s existing CT ratings.

Most importantly, it’s PROVEN to get RID of Nuisance Tripping issues – permanently.

Not only can the ETC-12 be set up to replicate the time-current characteristics of any of the Micrologic trip units, but it also offers the latest in control, selectivity, and Arc Flash Safety all packed into one, TRUSTED piece of state of the art circuit breaker life extension electronics.

All ETC-12 trip units are capable of providing full LSIG protection and allow the user to defeat any undesired bands. This means greater interchangeability and the ability to do more with less spares.

The ETC-12 also offers features that are simply NOT available on the older Micrologic control units. These features include a remote mountable display with digital three-phase ammeter, flashSAFE arc-flash reducing maintenance mode, MODBUS communications, and more.
