MC Miller JR-2 Current Interrupter #12830

Menu

MCM's model JR-2 is a high power interrupter with 100 amperes DC interrupting capability. The JR-2 (100 ampere current interrupter) and JR-1 (35 ampere current interrupter) are of compatible "mix" when being used for multiple interrupter test.

Features:

· 100 amp AC/DC interrupter

· Crystal controlled timing indicators

· Rechargeable battery

· Immediate or delayed interrupting operation

· Keyboard programmable

· Built-in cooling fan

· Synchronization better than 1 millisecond

· Capable of re-synchronization

· Low Battery indicator

Night Latch:

The JR-2 supports 24-hour timing and a scheduled relay closure period. For example, a night latch time of 1700 could be entered from the keypad, and a start time of 0700. The unit will operate normally until 1700, at which time the relay will close and will stay latched until 0700 the next morning, when the normal interrupter cycle will begin again. This feature facilitates full CP polarization during hours when the survey crews are absent.
