The breaker is rated for distribution applications and conforms to IEC 60898-1. ## Breaking capacity and voltage ratings Breaking capacity is 4.5 kA Icn at both 230 V AC and 400 V AC (50/60 Hz) per IEC 60898-1. Rated operational voltage is 400 V AC, insulation voltage 500 V AC, and impulse withstand voltage 4 kV. ## Terminal and mounting details Tunnel-type terminals accept 1 to 25 mm² rigid or 1 to 16 mm² flexible wire, torqued to 2 N·m. The breaker clips onto standard DIN rail, occupies 36 mm width (4 x 9 mm pitches), and stands 81 mm tall by 66.5 mm deep. The toggle handle provides local on/off control with a contact position indicator. IP20 finger-safe protection covers the terminals. ## Environmental and durability specs Rated for ambient operation from -25 to 60 °C, storage from -40 to 85 °C, with 95% relative humidity tolerance at the upper end. Mechanical durability is 10,000 cycles, electrical 4,000 cycles — typical for a residential or light-commercial MCB in this class. Pollution degree 2 and tropicalisation class 2 suit it for controlled indoor environments.","metaTitle":"Schneider Electric EZ9F34220 Easy9 MCB, 2P, 20 A, C-Curve, 4","metaDescription":"Schneider Electric EZ9F34220 Easy9 miniature circuit breaker, 2-pole, 20 A, C-curve, 4.5 kA breaking capacity per IEC 60898-1.
