Product details

It carries a TM240 thermal-magnetic overcurrent release and is rated for a continuous current of 200 A at 40 °C, derating to 176 A at 70 °C. The interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V, making it suitable for high-fault-current industrial distribution panels where selectivity and SCCR headroom are required.

Interrupting capacity and thermal performance

The continuous current holds flat at 200 A from 40 °C through 50 °C, then derates linearly to 176 A at 70 °C — no surprise if the panel runs warm. Power loss is 42 W maximum at rated load, which factors into enclosure ventilation calculations.

Panel integration and dimensions

The 4-pole width (140 mm) matches the standard 4-pole SENTRON 3VA frame — no oddball spacing. The TM240 release is factory-set; no undervoltage release or ground-fault module is included (specified as "without" on both).

Frequently asked questions

What is the interrupting capacity of 3VA1220-5EF42-0AB0 at different voltages?

The interrupting capacity is 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. These ratings cover most industrial distribution voltages.
