MCCB for line protection — 25 A continuous, 38-300 A adjustable trip
It carries a rated continuous current of 25 A at 40-70 °C with no derating across that range, and its adjustable thermal-magnetic trip unit covers 38 A to 300 A — meaning you can dial it to protect a feeder, a motor branch, or a sub-distribution board without swapping the breaker frame. Rated insulation voltage is 800 V, and the breaking capacity runs from 121 kA at 240 V down to 3 kA at 690 V — that 121 kA figure at 240 V is what you'd check for high-fault service-entrance or industrial main-breaker applications where the available fault current is substantial.
Integration into a panel — dimensions and mounting
The breaker measures 181 mm high by 105 mm wide by 86 mm deep. That 86 mm depth is the projection from the mounting surface — factor it into gland-plate clearance and door-swing if the panel is shallow.
The adjustable trip range (38 A minimum, 300 A maximum) means the same frame covers a wide spread of load sizes; you set the trip to match the conductor ampacity or the load's inrush, not the other way around. Ground-fault monitoring is built in as summation-current sensing on the line conductors — no external GFCI module needed. Communication function is present, so the breaker can report status or trip events over a bus in a monitored distribution system.
