Product details

Branch-circuit protection for resistive and lighting loads

The ABB 2CCS451001R0065 is a 1-pole miniature circuit breaker with a B tripping curve, rated 6 A continuous current and a short-circuit breaking capacity of 6 kA per IEC/EN 60898-1.

DIN rail fit and enclosure clearance

Overall depth of 94.5 mm and height of 89 mm — check the enclosure door clearance, especially if a busbar or wiring duct sits in front of the breaker row.

Rated insulation voltage and overvoltage category

Rated insulation voltage is 440 V, overvoltage category III — suitable for fixed-installation distribution boards downstream of the utility meter, where transient overvoltages up to 4 kV are expected. IP20 finger-safe terminals accept screw-clamp wiring; the housing is not rated for wet or dust-laden environments.

Current production — no lifecycle concern

It is suitable for both new panel builds and replacement spares. ABB lists no direct successor — this order code remains the active version for the B-curve, 6 A, 1-pole position.

Frequently asked questions

How can I order ABB 2CCS451001R0065 or check availability?

This is a current-production part sourced through independent distribution. Submit an RFQ with your BOM quantity; pricing and lead time are confirmed at quote time. No stock-holding claim is made here.

What does the B tripping curve mean for my circuit?

The B curve trips at 3 to 5 times the 6 A rated current — so between 18 A and 30 A for a magnetic trip. This is suited for resistive loads with low inrush; for motor or transformer circuits with higher starting current, a C or D curve breaker would be a better choice.

Can ABB 2CCS451001R0065 be used for DC applications?

The evidence does not list a DC voltage rating or DC breaking capacity. This breaker is specified for AC circuits at 440 V insulation voltage. For DC branch protection, consult the ABB DC-rated MCB series.
