Product details

What it is and what it does

The SENTRON 5SQ2160-0KA16 is a 1-pole miniature circuit breaker from the 5SQ series, rated 16 A with a B tripping characteristic. It breaks fault currents up to 3 kA per EN 60898 at 240 V AC, single-phase. That B-curve means it trips between 3 and 5 times rated current — standard for protecting lighting, receptacle, and general-purpose branch circuits where inrush isn't a concern.

Fit and panel integration

Snaps onto standard DIN rail, one width unit wide, with a 55 mm installation depth. IP20 finger-safe terminals — fine inside a closed panel, not for wet or dusty environments. Overvoltage category 3 means it's designed for fixed-installation downstream of the main distribution board.

Frequently asked questions

Where can I buy 5SQ2160-0KA16?

It is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the breaking capacity of 5SQ2160-0KA16?

3 kA per EN 60898 at 240 V AC.

What does the B tripping characteristic mean for this breaker?

It trips on overload between 3 and 5 times the 16 A rating, so it's suited for resistive or general-purpose loads without high inrush — lighting, receptacles, small control transformers.

Does 5SQ2160-0KA16 fit in a panel designed for 5SQ2360-0KA16?

The 5SQ2360-0KA16 is a 3-pole version; the 1-pole 5SQ2160-0KA16 uses the same 55 mm depth and DIN-rail footprint, so it drops into the same mounting but occupies one width unit instead of three. Rewiring for single-phase vs three-phase is required.
