CENTERLINE® Motor Control Centers Power Fuses
Application The information in this publication applies to the selection of 3-phase motor power fuses when used in 460V and 575V applications, as well as to the selection of power fuses in branch circuit or non-motor applications.
Refer to Publication 2100-PL001D-EN-P for ordering information.
Power fuses for motor applications are valid for the following Bulletin 2100 NEMA products:
• Bulletin 2106 Full Voltage Reversing Combination Staters• Bulletin 2112 Full Voltage Non-Reversing Combination Starters• Bulletin 2112 Full Voltage Non-Reversing Vacuum Combination Starters• Bulletin 2122 Two Speed Combination Starters• Bulletin 2126 Two Speed Reversing Combination Starters• Bulletin 2154F&G Combination Solid-State Controllers• Bulletin 2172 Reduced Voltage Autotransformer Combination Starters
Power fuses for branch circuit or non-motor applications are valid for the following Bulletin 2100 NEMA products.
• Bulletin 2100D Miscellaneous Units with Fusible Disconnects• Bulletin 2102L Full Voltage Lighting Contactors• Bulletin 2102H Full Voltage Lighting Contactors (High Harmonic
Applications)• Bulletin 2192F Fusible Disconnect Feeders• Bulletin 2192M Fusible Disconnect Mains• Bulletin 2196 Control and Lighting Transformers with Fusible
Disconnects
All power and time delay fuses are UL Class/CSA HRCI as follows: Class CC/HRCI-MISC., Class J/HRCI-J, Class RK1/HRCI-R, and Class L/HRCI-L. The HRCII-C fuses specified for use in Canada are NOT time delay fuses and also are applicable for motor loads only (must be used in conjunction with a motor overload relay). Please note that the Class R fuse is an RK1 and DOES NOT include the RK5 type. The RK5 type may allow too much let-through energy during a short circuit and, therefore, may not offer the best protection.
For a particular application, see the table guide (Table B) which shows the types, manufacturer, and application.
2 CENTERLINE® Motor Control Centers Power Fuses
The Allen-Bradley pre-selected motor application power fuses (Tables C though G), are based upon fuse manufacturer’s recommendations, Allen-Bradley investigative testing, and requirements of the National Electrical Code/Canadian Electric Code (NEC/CEC). Supplied CC, J, and RK1 time delay fuses specified for the Typical motor acceleration time applications are in accordance with IEC 947-4-1 test requirements and allow for Type 2 Short Circuit Coordination.
Motor Application Motor application power fuse selection is available in two (2) acceleration ranges:• Typical motor acceleration time for non-plugging or non-jogging applications.
Typical motor acceleration times are 5 seconds or less.• Long motor acceleration time for applications, where the motor acceleration
times are greater than 5 seconds, for cases of light plugging or jogging, some code letter motors, and some high efficiency motors.
Non-Motor Application The customer selects the proper power fuse for branch circuit or non-motor applications (Table H through P), other than transformer applications, based on load and NEC/CEC requirements. Additionally, the power fuse rating is limited by the disconnect/fuse clip rating available for the particular application, see Table A.
A particular disconnect fuse clip rating will allow for a particular range of fuse ratings, e.g., a 60 ampere disconnect fuse clip will accommodate fuse ratings from 31 amperes to 60 amperes. In addition, the fuse selection tables only allow for “standard ampere rating” fuses as defined in the NEC/CEC.
The Allen-Bradley pre-selected power fuses for control and lighting transformer applications (Table Q), are based on the primary protection requirements as found in the NEC/CEC. Additionally, the disconnect/fuse clip rating limits the maximum available power fuse rating for the particular transformer application.
