The TM110M thermal-magnetic release gives it an adjustable magnetic trip point fixed at 64 A (li min = li max), so short-circuit protection is locked in at 16× the continuous rating.
This MCCB delivers 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — numbers that put it in the high-fault-current class for a 4 A frame. At 500 V and 690 V the rating drops to 7.5 kA, which is typical for a starter-protection device on a 4 A continuous rating; the high-fault capability at lower voltages means it can be used downstream of a transformer or in a high-capacity bus without needing a current-limiting fuse upstream.
The 76.2 mm width (3 in) and 130 mm height (5.12 in) fit a standard MCCB panel cutout or DIN-rail adapter plate. The optional motor drive (listed as a product extension) allows remote switching if needed.
