Thermal-magnetic trip unit

Overview

— Power Distribution Protection

The thermal-magnetic trip units • TMD
• TMA
are used for the protection of AC Motor Protection
and DC networks. They are a • MA
Generator Protection
solution for systems where only • TMG
protection against overloads and
short-circuits are needed.

Key:
1. Current threshold
for short-circuit
protection;
2. Rotary switch 2 4
for short-circuit
protection;
3. Current threshold
for overload
protection;
4. Rotary switch for
overload threshold
setting.
Rotary switch
Depending on the version it is possible to set the
desired thresholds for protection by turning the
front rotary switch.
