Its TM-D thermal-magnetic trip unit handles distribution loads — think panel feeds, sub-distribution boards, or as a main breaker in a small switchboard — where the trip curve needs to be fixed and reliable, not adjustable. It carries EN/IEC 60947-2 certification and is suitable for isolation, so it doubles as a visible-break disconnector in the closed position — no separate isolator needed upstream for many installations.
Mounting and integration into a panel
At 108 mm wide × 137 mm high × 80 mm deep, it takes 12 module pitches of 9 mm on a DIN rail or busbar system. Connection is front-front via compression lugs or busbars — no rear-access requirement, which simplifies gland-plate layout and keeps the wiring within reach of a standard panel hand. Neutral is on the left. The IP40 front face keeps dust and accidental finger contact out of the mechanism; IK07 impact resistance handles the odd dropped screwdriver during commissioning. If the panel sees washdown or outdoor exposure, you'll want a separate enclosure — this breaker isn't sealed for wet environments.
