Product details

The Schneider Electric EZ9F26120 is a 1-pole Easy9 miniature circuit breaker rated 20 A with a B-curve trip characteristic and 6 kA breaking capacity at 230 V AC per IEC 60898-1.

The 20 A rated current (In) handles continuous loads up to that level; the 6 kA Icn at 230 V AC tells you it safely interrupts a fault current up to 6,000 A without welding contacts or cascading upstream. Thermal-magnetic trip technology combines a bimetal strip for overload protection (slow, heat-dependent) and a solenoid for short-circuit protection (instantaneous).

Clip-on mounting to a DIN rail (35 mm per EN 60715) with tunnel terminals accepting 1...25 mm² rigid or 1...16 mm² flexible cable. The 18 mm width and 66.5 mm depth fit standard distribution boards; grey (RAL 7035) housing matches the Easy9 family aesthetic.

Frequently asked questions

What is the breaking capacity of EZ9F26120?
