Product details

Siemens 5SY3016-6KL — SENTRON 1P+N MCB, 16 A B-curve, 4.5 kA

The Siemens 5SY3016-6KL is a SENTRON miniature circuit breaker (MCB) rated 16 A at 230 V AC with a B tripping characteristic and a 4.5 kA breaking capacity per EN 60898. The 1P+N pole configuration switches the line and switches the neutral — the N pole is switched but not protected, which is the standard arrangement for single-phase final subcircuits in TN and TT systems where overcurrent protection on the neutral is not required. The B curve (3–5× In instantaneous trip) suits resistive and general-purpose loads with low inrush — lighting, socket outlets, small appliances — where a C curve would nuisance-trip on start-up.

Mounting position any; no derating for horizontal or inverted orientation. Terminal torque range 17.7 to 22.1 lbf·in — a standard screwdriver bit handles it.

Construction and compliance

Halogen-free and silicon-free construction — no silicone outgassing that could contaminate relay contacts or optics in a mixed panel. Sealable with a lead seal (tamper-evident cover included). Vibration-resistant per IEC 60068-2-6. Touch protection on the terminals is standard.

Frequently asked questions

What is the breaking capacity of 5SY3016-6KL?

4.5 kA rated short-circuit capacity per EN 60898 at 230 V AC. That is the standard domestic and light-commercial interrupting rating for this class — sufficient for most TN final subcircuits, but verify against the prospective short-circuit current at the point of installation.

Where can I buy the Siemens 5SY3016-6KL?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.

What is the difference between 5SY3016-6KL and 5SY6008-7?

The 5SY6008-7 is a C-curve 8 A MCB with a 6 kA breaking capacity. The 5SY3016-6KL is a B-curve 16 A with a 4.5 kA rating. Both are 1P+N, 18 mm wide, same depth, same SENTRON family. They share the same footprint and terminal torque range, so a panel wired for one can accept the other without rewiring — but the trip curve and current rating differ, so the substitution must be validated against the circuit design.
