Product details

Breaking capacity is 75.6 kA at 240 V AC, 52.5 kA at 415 V, and 32 kA at 440 V.

Integrated auxiliaries and releases

The UVR drops the breaker on loss of control voltage — standard for emergency-stop chains or undervoltage protection schemes. The auxiliary contacts report breaker position back to the PLC or status panel without a separate contactor block. No communication module or ground-fault monitoring on this order code. If you need Modbus or RCM, step to the 3VA2 communication-capable frame. The 3VA1 platform here is a pure electromechanical MCCB with a trip-indicator flag.

The 3-pole footprint is standard for the 3VA1 frame — drops into the same cutout as the 3VA1 160 A frame, so a panel laid out for a larger rating accepts this 50 A unit without rework.

Frequently asked questions

What is the breaking capacity of this MCCB at different voltages?

75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. The interrupting rating drops with voltage, which is typical for a current-limiting MCCB design.

Does this breaker include an undervoltage release?

Yes, it ships with an undervoltage release (UVR) fitted as the auxiliary release, plus two auxiliary switches and one trip alarm switch (HQ). The UVR trips the breaker when control voltage drops below the dropout threshold.

Where can I buy the 3VA1050-3ED36-0CH0 and how is it quoted?
