Product details

The Siemens 5SJ6510-7 is a SENTRON 5SJ6 miniature circuit breaker with a 1P+N pole configuration, C-curve tripping characteristic, rated 10 A at 240 V AC. The 1P+N design switches the line conductor and switches the neutral, but does not protect the neutral — it's sized for single-phase final subcircuits where neutral protection isn't required by code.

Mounting and integration — fits standard DIN-rail enclosures

Touch protection is built in, so accidental contact with live terminals is prevented when the breaker is properly installed.

Frequently asked questions

What is the breaking capacity of the 5SJ6510-7?

The 5SJ6510-7 has a 6 kA breaking capacity per EN 60898 and also 6 kA per IEC 60947-2. That rating is sufficient for most residential and light commercial distribution boards where the prospective short-circuit current is under 6 kA.

What does the C-curve mean on this MCB?

The C-curve trips between 5 and 10 times the rated current (50–100 A for this 10 A breaker). It is the standard characteristic for general-purpose loads such as lighting circuits, small motors, and control transformers — it tolerates moderate inrush without nuisance tripping.

Where can I buy the 5SJ6510-7 and how is it quoted?

The 5SJ6510-7 is sourced through independent distribution and quoted to order against an RFQ. Submit a request with your quantity and delivery needs; availability and current pricing are confirmed at quote time.

Will the 5SJ6510-7 fit in a panel designed for the 5SJ6220-6?

Both are 2-width-unit SENTRON 5SJ6 breakers with the same 70 mm installation depth and DIN-rail mounting. The 5SJ6510-7 is 1P+N (switched neutral) while the 5SJ6220-6 is 2-pole (both poles protected). They share the same footprint and terminal layout, so the 5SJ6510-7 will physically fit in the same panel position, but check whether your circuit requires neutral protection — the 5SJ6220-6 provides it, the 5SJ6510-7 does not.
