Breaking capacity and selectivity
The 3VA2325-5HL32-0BH0: The 187 kA at 240 V is the highest short-circuit current this MCCB can safely interrupt — useful for high-fault utility feeds or large transformer secondaries. At 415 V and 440 V the rating drops to 121 kA, and at 690 V it holds 17 kA. That spread means the breaker can be applied across a range of system voltages without losing fault-clearing capability, but the 690 V figure is the one to check for 690 V line-ups.
Thermal derating and ambient limits
The breaker carries its full 250 A rating from 40 °C up to 50 °C. Above that, derating begins: 240 A at 55 °C, 235 A at 60 °C, 230 A at 65 °C, and 225 A at 70 °C. If the panel ambient runs hot — say, near a drive stack or in a poorly ventilated enclosure — the continuous current must be reduced accordingly. Operating range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
Auxiliary and release configuration
This variant includes an undervoltage release (UVR) as the auxiliary release, plus 2 auxiliary switches and 1 trip alarm switch (HQ configuration). The supplied basic switch is order code 3VA2325-5HL32-0AA0; the integrated auxiliary trip is 3VA9608-0BB11. The trip indicator is present. No voltage trigger, no communication function, no phase failure detection, and no ground fault monitoring are fitted.
Physical footprint
Dimensions are 248 mm high, 138 mm wide, and 110 mm deep. The 138 mm width is standard for a 3-pole MCCB in this frame size — fits the typical panel cutout and busbar spacing. Maximum power loss is 40 W.
