The TM-D trip unit gives you LI protection: thermal overload (L) for sustained overcurrents and magnetic short-circuit (I) for fast clearing of high faults.
This breaker mounts fixed to a backplate — no DIN-rail clip, so plan for screw-terminal lug landing on a busbar or cable. Both line and load connections are front-facing screw terminals with a 25 mm pitch, which keeps wiring neat in a row of breakers. At 100 mm wide × 130 mm tall × 60 mm deep, it fits standard distribution board cutouts.
The utilisation category A rating confirms it's not intended for motor starting duty (that would be category B with a dedicated magnetic-only trip), so keep it on feeder and sub-distribution circuits. The electrical durability of 8000 cycles at rated current and 415 V is typical for this class — fine for a panel that sees occasional switching, not for a daily disconnect application.
