Interrupter Overview
The MicroMax GPS300, GPS350, and GPS360 interrupters are fully programmable, satellite-
synchronized interrupters that are capable of interrupting rectifier, bond, or any other current. Cycles
can be programmed using any combination of time intervals between 0.1 seconds and 999.9
seconds (in 0.1 second increments) for "Off" and "On" cycles. The interrupters can store up to 9
interruption programs for later use.

The MicroMax GPS350 and GPS360 also include a built-in solid state relay (normally closed) that can
interrupt either AC or DC, up to 60 A with on/off cycles of less than 4 seconds and 80 A with cycles
totaling 4 seconds or longer. The relay can be easily installed without concern for polarity. The
GPS360 includes a battery for use without an external power source.
