MCCB for line protection — 32 A, 3-pole, high interrupting capacity
Breaking capacity scales with system voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — meaning this breaker handles high-fault-current scenarios common in industrial mains or transformer secondary feeds without cascading upstream.
The 32 A rating holds from 40 °C through 50 °C ambient; above that it derates linearly to 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C.
Auxiliary and undervoltage release configuration
The integrated auxiliary trip module is order code 3VA9608-0BB25 — if you need a spare or replacement, that's the mate. No voltage trip, no communication function, no phase-failure detection, and no ground-fault monitoring on this version — it's a straight line-protection breaker with undervoltage release.
Dimensions are 76.2 mm wide, 130 mm tall, 70 mm deep — standard 3-pole MCCB footprint for a 32 A frame. No trip indicator on the front; status is read through the auxiliary switch contacts.
