Rated 20 A continuously at 40 °C (derates slightly to 19 A at 60 °C), it's sized for moderate branch circuits in commercial or industrial distribution panels.
Breaking capacity — what those voltage columns mean
This breaker carries a symmetrical interrupting capacity of 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 steep drop above 440 V is typical for an MCCB with a 20 A frame — at higher system voltages the arc energy is harder to quench, so the breaker is only rated for those lower fault levels.
Auxiliaries and releases — built-in, not add-on
The auxiliary switches provide remote status (open/closed) to a PLC or indicator lamp.
At 70 mm deep, 76.2 mm wide (3 inches), and 130 mm tall (5.12 inches), this breaker occupies a standard 3-pole MCCB footprint.
