H. Installation Torque for Circuit Breaker, Relay, Contactor, and Time Delay Module Terminals
NOTE: If a terminal torque value is specified on the circuit breaker, relay, contactor, or time delay
module, use that torque value.
NOTE: If the relay, contactor, or time delay module part number is not shown in Table 12, use the
torque values specified in Table 13.
NOTE: For the MS27751-( ) relays, use the torque values specified on the relay.
If the torque values are not specified on the MS27751-( )relay, use the values in Table 12
specified for the MS27751-( ) relay.
