Table 1.1a CURRENT Protection Functions for Digitrip 1150/1150i Trip
Notes: 1. ANSI/UL versions are limited to 1200 Amperes to comply with UL and NEC standards.
2. Four cause of trip LEDs indicate LONG, SHORT, INST or GROUND trip. Making Current Release and the
separate High Instantaneous Module are indicated by the Instantaneous LED.
3. An additional setting is marked M1 where:
Standard Circuit Breaker M1 = 14 x In for Plug Amps 100 through 1250A
M1 = 12 x In for Plug Amps 1600, 2000, 2500A
M1 = 10 x In for Plug Amps 3000, 3200A
Double Wide Circuit Breaker M1 = 14 x In for Plug Amps 2000, 2500A
M1 = 12 x In for Plug Amps 3000, 3200, 4000, 5000A (see Section 2.5)
M1 = 10 x In for Plug Amps 6000A, 6300A
4. Only available when Long Time I
2
T is selected.
5. Phase protection with 3 TRIP response types (See Section 4.2.1).
