Current Derating
Operation in ambient temperatures exceeding 40°C [104°F] is
possible if the power dissipation is limited either by reducing
the steady-state current or by reducing the duty cycle of the
soft starter as shown in
Table 6
.

IMPORTANT
When using electrical or pneumatic tools for screw termi-
nals, observe maximum torque limits.
Short Circuit Protection
Short circuit protection is divided into two levels —
Type 1 and Type 2.
Type 1 — protects the installation
Type 2 — protects the installation and the
semiconductors inside the motor controller
Short Circuit Protection by Circuit Breaker
A 3-phase motor with a correctly installed and adjusted over-
load relay will not short-circuit totally to earth or between the 3
phases. Part of the winding will normally limit the short circuit
current to a value that will cause instantaneous magnetic trip-
ping of the circuit breaker without damage to the soft starter.
The magnetic trip response current is approximately 11 times
the maximum adjustable current.
