Product details

50 A MCCB with 70 kA interrupting rating

Mounting and connection

Mounts on a backplate in horizontal or vertical orientation. Front-facing Everlink lugs accept rigid or stranded aluminium/copper up to 95 mm² (70 mm² flexible), which covers most panel feeder and subfeed applications. The 9-module pitch (81 mm wide) fits standard enclosure cutouts.

Durability and duty

Rated for 20,000 mechanical cycles and 20,000 electrical cycles at 440 V In/2 (10,000 at full In). That aligns with typical panel-switchgear life for distribution duty — not for frequent motor starting, but fine for branch-circuit protection where switching is occasional.

Frequently asked questions

What is the breaking capacity of C11H3TM050L?

70 kA at 415 V AC (H performance level).

What terminals does the C11H3TM050L use?

Front-facing Everlink lugs accepting 2.5–95 mm² rigid or stranded aluminium/copper, and 2.5–70 mm² flexible copper.
