Product details

The long-time pickup (Ir) adjusts from 250 to 630 A in nine steps — so you set the actual load current here, not the breaker frame. The short-time pickup (Isd) ranges from 1.5 to 10 × Ir, and the instantaneous pickup (Ii) from 1.5 to 11 × In. That wide adjustment range lets you coordinate selectively downstream: set Isd high enough that a branch fault clears before this unit sees it.

Deployment context

The trip unit mounts into a ComPacT NSX400...630 fixed or drawout breaker. The LCD display shows real-time ammeter readings, protection settings, and event logs. The unit supports zone selective interlocking (ZSI) for faster fault clearing in a coordinated distribution system.

Frequently asked questions

What standards does C6335Z630 comply with?

It is designed and tested to EN/IEC 60947-2, the standard for low-voltage switchgear and controlgear — specifically for molded-case circuit breakers. This covers the trip unit's protection functions, dielectric strength, and short-circuit performance.

Where can I buy C6335Z630?

This trip unit is sourced and quoted to order against an RFQ through independent distribution. Current pricing and availability are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the protection scheme on this trip unit?

LSI: long-time overload (L) with adjustable pickup 250–630 A and delay 15–400 s at 1.5 × Ir; short-time short-circuit (S) with adjustable pickup 1.5–10 × Ir and delay 0–0.4 s; instantaneous short-circuit (I) with adjustable pickup 1.5–11 × In.
