What this MCCB carries
The 3VA1180-6EF32-0DH0 is a 3-pole SENTRON molded case circuit breaker rated for 80 A continuous current (Iu) with a TM240 thermal-magnetic overcurrent release. Its interrupting capacity hits 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — numbers that tell you it's built for high-fault panels where upstream coordination matters. The 800 V rated insulation voltage (Ui) covers most industrial distribution voltages without derating concerns. This breaker includes an undervoltage release (UVR) as standard, plus a 2-auxiliary-switch + 1-trip-alarm-switch HQ contact block. The UVR means the breaker drops out when control voltage falls below a threshold — useful for emergency-stop circuits or loss-of-mains protection. The auxiliary contacts give remote status feedback without adding a separate module.
Panel fit and thermal derating
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep. That 70 mm depth is shallow enough for most 200 mm deep enclosures without forcing a deeper gland plate. The 76.2 mm width (roughly 3 inches) is a standard MCCB footprint — it'll land on a DIN rail or panel-mount base without re-drilling. Thermal derating is flat up to 50 °C — still 80 A. At 55 °C it drops to 76.8 A, at 60 °C to 75.2 A, at 65 °C to 73.6 A, and at 70 °C to 72 A. If your panel ambient runs hot, you lose less than 10 % at the top end. Storage range is -40 °C to 80 °C; operating range is -25 °C to 70 °C.
What the TM240 release means for coordination
The TM240 overcurrent release is a thermal-magnetic type — the thermal element handles overloads (long-time delay), the magnetic element handles short-circuits (instantaneous). The '240' likely refers to the frame size or trip unit family; it's not a direct current setting. For selectivity studies, the 220 kA at 240 V gives headroom downstream, but the 17 kA at 690 V is the limit if you're feeding a 690 V motor. The manual covers DC network ratings separately.
