Single-Pole Thermal-Magnetic Control Circuit Protectors
Single-Pole Type GCB Circuit Protector Blocks |
A. Thermal-magnetic circuit protector B. 14 different current ratings: 0.1–15 A C. On-Off switch D. Visible trip indication E. Mounts on Class 9080 GH track and on DIN mounting track |
|
NOTE: 9080GCB circuit protector blocks
have solderless box lugs. They accept one CU 6.0 (10)–1.5 (16)
wire (for example, the wire gauge conversion of 6.0 mm2 is (10) AWG).

Selection:
-
Determine the inrush correction factor from the table Inrush Ratio Correction.
-
Determine the temperature correction factor from the table Ambient Temperature Correction.
-
Determine the sealed current of the load that is being protected.
-
Multiply the sealed current by the two correction factors and choose the closest circuit protector.
Example:
A solenoid with sealed current of 0.75 A, an inrush ratio of 1:6, and in an ambient temperature of 85 °F (29.4 °C):
-
0.75 x 1.5 x 1.05 = 1.18
-
Choose the 1.2 A protector
The 9080GCB circuit protectors come standard with the track adapter for mounting on 9080GH track (replacement adapter is 9080GH64). Removal of this adapter permits mounting on 9080MH2●●, MH3●●, and AM1 track. See Mounting Tracks for a complete listing of available tracks.

These maximum current values assume the use of insulated copper conductors with 167° F (75° C) temperature rating, and are calculated based on NEC Article 310, Table 310-16. In most cases this value is the maximum ampacity of that wire or combination of wires (as listed in the above table Maximum Current Values) which has the greatest current carrying capacity. The actual allowable current for a particular application is dependent on the number, size, insulation class and other characteristics of the wires used.

Tripping Time
Tripping time of the circuit protector is determined from the values in the table Tripping Time in Seconds at 70 °F (21.1 °C). Divide the circuit protector value by the temperature correction factor from the table Ambient Temperature Correction above to determine the actual rated current referenced in the table Tripping Time in Seconds at 70 °F (21.1 °C).

NOTE: When several protectors are channel

will be 80% of rated current at 70 °F (21.1 °C).
