Product details

It occupies a single 18 mm modular width on standard DIN rail, with any mounting position allowed. The breaker is rated for 400 V AC and 60 V DC, with a breaking capacity of 10 kA per EN 60898 and 15 kA per IEC 60947-2.

It's halogen-free and silicon-free, which matters in clean-room or semiconductor-adjacent zones where outgassing can contaminate optics or wafers.

Standards and approvals context

The breaker is designed to EN 60898 (10 kA) and IEC 60947-2 (15 kA) — the two key standards for miniature circuit breakers in Europe and international markets. The IP20 protection (with connected conductors) and IP40 in the handle range are typical for panel-mounted MCBs; the unit is not intended for wet or hose-down environments without an additional enclosure. It's suitable for environment B per EMC classification, meaning immunity to interference is not applicable — standard for passive protective devices.

Frequently asked questions

What are the key breaking capacity ratings?

It is rated 10 kA per EN 60898 and 15 kA per IEC 60947-2. The higher IEC figure applies in industrial panel applications where fault current capability is a design requirement.

What is the physical size and mounting?

Width is 18 mm (1 modular unit), height 121 mm, depth 70 mm. It snaps onto standard 35 mm DIN rail and can be mounted in any position.

What is the ambient temperature range?

Operating ambient temperature ranges from -40 °C to 75 °C, with up to 95% humidity. This covers most outdoor and unconditioned enclosure environments.

Is this breaker halogen-free and silicon-free?

Yes, it is both halogen-free and silicon-free, making it suitable for clean-room or sensitive manufacturing environments where outgassing must be minimized.
