Product details

It carries 50 A continuously at 40 °C ambient, derating to 45 A at 70 °C — the thermal-magnetic trip unit (TM210) handles overload and short-circuit protection without a separate undervoltage release. Breaking capacity is what sets this MCCB apart: 121 kA at 240 VAC, 75.6 kA at 415 VAC, 52.5 kA at 440 VAC, and 11.9 kA at both 500 VAC and 690 VAC.

At 70 mm deep, 76.2 mm wide, and 130 mm tall, this 3-pole MCCB fits standard SENTRON 3VA panel footprints. The shunt trip adds a control-wire connection alongside the power lugs; verify free-wheeling diode polarity on the trip coil if driving it from a 24 VDC PLC output — the coil suppression is internal but polarity-sensitive.

Frequently asked questions

Where can I buy 3VA1050-4ED36-0KA0 and how do I get a price?

This part is sourced to order through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time, no stock count or price listed here.

What is the breaking capacity of 3VA1050-4ED36-0KA0 at different voltages?

121 kA at 240 VAC, 75.6 kA at 415 VAC, 52.5 kA at 440 VAC, and 11.9 kA at both 500 VAC and 690 VAC.

Does 3VA1050-4ED36-0KA0 include a shunt trip?

Yes, the design of the auxiliary release is a shunt trip (STL), enabling remote tripping via a control signal.
