Description
Product: circuit breaker Easypact EZC250N – TMD – 250 A – 4 poles 3d
This is a 250A circuit breaker for EasyPact EZC250N. This product operates below rated operational voltage(Ue) 550 V AC at 50/60 Hz or 250 V DC network. The ultimate breaking capacity(Icu) varies depending on network conditions; Ics=50% Icu if matching is needed. Designed as a 4 poles frame with detection on 3 poles, equipped with TM-D trip unit for thermal-magnetic protection. Complies with IEC60947 standard, CE certified and independently certified by KEMA, ASEFA, TUV, and third-party Tilva. Certified for operation in pollution degree III environment as per IEC60947, passing tests under extreme atmospheric conditions.
Mounting supported vertically or horizontally in metal enclosure; features safety padlocking. Protection degree is IP40 for direct rotary handle and IP54 for extended rotary handle. The product design includes slots for indication or voltage release auxiliaries positioning behind the front cover. Fixed dimensions: width 14 cm, height 16.5 cm, depth 6 cm.
