MCCB for line protection — 25 A, 3-pole, TM210 release
It carries a 25 A continuous rating at 40 °C ambient, holds that rating through 50 °C, then derates to 24 A at 55–60 °C and 23 A at 65–70 °C — so in a warm enclosure you lose roughly 1 A per 5 °C above 50 °C. The TM210 thermal-magnetic release handles overloads and short-circuits without an external trip unit. Breaking capacity is the headline number for fault duty: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
Auxiliary switching and trip indication
The trip indicator gives a local visual flag that the breaker has opened on fault — useful for panel walk-downs.
