Product details

It's a distribution-class breaker (Category A per IEC 60947-2) rated for 36 kA Icu at 440 V AC, 50/60 Hz — enough fault-interrupting capacity for most low-voltage distribution panels feeding motor control centers or lighting sub-distribution. The TM-D trip unit provides short-circuit and overload protection, with a fixed magnetic trip threshold of 6000 A. No earth-leakage protection built in — that's a separate add-on if the application needs it.

Fixed backplate mount, front-front connections (line and load both front-facing). Connection pitch is 45 mm. Dimensions: 255 mm high, 185 mm wide, 140 mm deep. IP20 finger-safe protection on the front; IK07 impact resistance. The toggle handle gives positive contact indication — you can see and feel the open/closed state. Mechanical durability is 10,000 cycles; electrical durability is 4,000 cycles at 415 V AC (Category A). That's enough for a main breaker that gets cycled a few times a year, but not for a switching duty on a frequent-start load.

Listed to EN/IEC 60947-2, EN/IEC 60947-1, JIS C8201-2-2, and GB/T 14048.2. That covers most global markets — Europe, Japan, China.
